Fine needle aspiration cytology of glycogen-rich clear cell carcinoma of the breast: review of 37 cases with histologic correlation

OBJECTIVE: To analyze fine-needle aspiration cytology (FNAC) material from 37 cases of breast glycogen-rich clear cell cancer (GRCC) and correlate cytomorphologic features with histologic appearance to determine characteristics of GRCC on FNAC. STUDY DESIGN: We reviewed cytologic features of 37 cases of breast GRCC from the archives of Ege University Hospital diagnosed between 1994 and 2006. RESULTS: Thirty-seven patients with available aspirate and confirmed GRCC were identified. The female patients ranged from 32 to 81 years (mean 52 years). The initial cytologic diagnoses were adenocarcinoma for 27 and atypical or suspicious for cancer for 10. The cytologic picture was characterized by hypercellular tumor cells in loosely cohesive syncytial groups and some single cells. Most tumor cells had abundant, finely granular eosinophilic cytoplasm or foamy to clear cytoplasm with well-defined cytoplasmic membranes and moderate to marked nuclear pleomorphism with prominent nucleoli. Histologic examination confirmed all cases to be pure GRCC. ConCLUSION: Breast GRCC is a rare, distinct category with cytologic features that overlap considerably with those of other carcinomas. Awareness of variability in cytomorphologic appearance of GRCC and routine assessment for glycogen facilitate accurate diagnosis of these lesions by FNAC and enable prompt treatment of these poor-prognosis breast cancers.     

Cytologic features of subependymal giant cell astrocytom: a review of 7 cases

OBJECTIVE: To describe the cytologic features of subependymal giant cell astrocytoma (SEGA) on smears and analyze cytomorphologic parameters that may help in reaching the diagnosis of SEGA. STUDY DESIGN: Cytologic smears of 7 cases of SEGA were reviewed and graded semi-quantitatively for 11 cytologic features: clustering, cytoplasmic fibrillary processes (fibrillarity), cellularity, small prominent nudcleoli, binucleation or multinucleation, "strap cells", spindle-shaped cells, mitoses, intranuclear inclusions, nuclear atypia and perivascular palisading/pseudorosettes. Corresponding histologic sections were also reviewed. RESULTS: The study included 5 male and 2 female patients with an average age of 8.3 years (range, 3-16) at surgery. Cytologic examination revealed loosely cohesive clusters of large cells possessing round to oval nuclei with no or minimal atypia; fine, evenly distributed chromatin; and abundant eosinophilic cytoplasm enmeshed in abundant thin, hairlike processes. Predominant features included hypercellularity, cell clustering, and fibrillarity. Binucleation or multinucleation; small, prominent nucleoli; and strap cells were often seen. Although common in histologic sections, perivascular palisading/pseudorosettes and spindled astrocytic cells were rarely noted on smears. CONCLUSION: The cytologic features of SEGA are highly characteristic and thus are of great use in supporting a diagnosis of SEGA and in excluding mimics, primarily gemistocytic astrocytoma and ependymoma.     

Lymphoepithelioid cell lymphoma (Lennert's lymphoma). Report of a case with fine needle aspiration cytology

BACKGROUND: Lymphoepithelioid cell lymphoma (LCL) is a rare morphologic variant of peripheral T-cell lymphoma. Although their histopathologic and immunohistochemical findings are well known, the cytopathologic features have not been well documented. This report describes the fine needle aspiration cytology (FNAC) findings of a case of LCL. CASE: A 75-year-old woman presented with cervical, supraclavicular, axillary and mediastinal lymphadenopathy. FNAC of a cervical lymph node was performed. The smears contained a polymorphous infiltrate formed by abundant histiocytes disposed singly or in clusters, small and medium-sized to large atypical lymphoid cells and reactive cells, including eosinophils and plasma cells. Isolated capillary-sized vessels also were observed. Histopathologic and immunohistochemical examination confirmed the diagnosis of Lennert's lymphoma. CONCLUSION: Although histopathologic and immunohistochemical studies were required for a definitive diagnosis, the findings of FNAC in this case appeared distinctive and suggested the possibility of LCL.     

A cytologic perspective on meibomian gland carcinoma

OBJECTIVE: To reevaluate and reestablish the reproducible diagnostic cytomorphologic features of meibomian gland carcinoma (MGCA), demonstrating the importance of fine needle aspiration cytology (FNAC) in eyelid lesions and leading to better management of the tumor. STUDY DESIGN: Cytologic smears ofpreviously diagnosed cases of MGCA over a 3-year period were collected, along with their histopathology reports. The cytomorphology of the histopathologically proven cases were reevaluated in greater detail. The cytologic smears were stained with Leishman-Giemsa cocktail and Papanicolaou stain, and the histopathologic sections were stained with hematoxylin-eosin. Special stains and immunohistochemical stains were applied as required. RESULTS: Of the 19 cases, 3 diagnosed as MGCA on cytologic examination were reported as basal cell carcinoma on histopathology. On reevaluation of the cytologic smears, in addition to the regular characteristic features of MGCA, interesting findings such as an isolated dispersed cell population in a bubbly background, signet ring cells, pseudo-mucin cell balls, giant cell reaction and hyaline-like round bodies were observed. CONCLUSION: This study emphasizes the cytomorphologic features of MGCA in addition to those described in the literature, which could be of a great help in its diagnosis. Further, it emphasizes the importance of FNAC in the diagnosis of MGCA.     

Fine needle aspiration cytology of primary non-Hodgkin's lymphoma of the tongue. A case report.

BACKGROUND: Fine needle aspiration cytology (FNAC) of extranodal non-Hodgkin's lymphoma of the tongue has rarely been described. CASE: A 47-year-old male was referred to the cytology laboratory for FNAC of a 3-cm-diameter swelling on the dorsum of the tongue, with a primary clinical diagnosis of soft tissue tumor. FNAC smears showed discrete, monomorphic, round to oval cells with scanty, deep blue cytoplasm. The nuclear margin was regular, with occasional prominent nucleoli and fine nuclear chromatin. The background showed many lymphoglandular bodies. The cells were strongly positive for leukocyte common antigen. A cytologic diagnosis of high grade non-Hodgkin's (NHL) was offered and subsequently confirmed by histopathology. CONCLUSION: Primary NHL of the tongue is relatively rare. As there are no characteristic clinical features of extranodal NHL of the tongue, FNAC may be useful for rapid diagnosis and management of such cases.     

Fine needle aspiration cytology of Langerhans cell histiocytosis of the thyroid. A case report.

BACKGROUND: Langerhans cell histiocytosis (LCH) of the thyroid is a rare condition, and fine needle aspiration cytology (FNAC) of this entity has rarely been described. CASE: FNAC was done on a 3-cm-diameter thyroid swelling in the left lower lobe of the thyroid gland. Smears showed a large number of lymphocytes, eosinophils, thyroid follicular cells and discrete, large cells with prominent nuclear grooves. Mitotic activity was frequent. A cytologic diagnosis of LCH was offered. Subtotal thyroidectomy was performed, and the cytologic diagnosis was confirmed by histology. CONCLUSION: LCH of the thyroid has certain salient diagnostic features. The presence of histiocytes with prominent nuclear grooves, reactive lymphoid cells and eosinophils along with benign thyroid follicular cells should raise the suspicion of this rare entity on FNAC smears of the thyroid.     

Fine needle aspiration cytology of lobular breast carcinoma. Comparison with other breast lesions

OBJECTIVE: To analyze the detailed cytomorphology of lobular breast carcinoma and to compare the cytologic smears of benign, borderline and infiltrating duct carcinoma. STUDY DESIGN: Fine needle aspiration cytology (FNAC) smears of histopathologically proven infiltrating lobular carcinoma (ILC), infiltrating ductal carcinoma (IDC), borderline lesions and benign breast lesions were selected for study. Detailed cytomorphologic analysis of the smears was carried out on hematoxylin and eosin- and May-Grünwald-Giemsa--stained slides, and a comparison of results was done. The various cytologic features were also graded semi-quantitatively with the numerical score; logistic regression analysis was done. RESULTS: There were 25 cases of ILC, 30 of IDC, and 10 borderline and 18 benign lesions. Cytologic diagnosis of malignancy on FNAC smears of ILC was offered in 19 cases; of them, 2 cases were diagnosed as ILC. The remaining six cases were diagnosed as borderline (four) and benign lesions (two). Overall sensitivity in detection of malignancy in ILC cases was 76%. FNAC smears of ILC showed moderate (52%) to abundant (32%) cellularity. The cells of ILC were arranged both in clusters and in dissociation (72%). Individual cells were monomorphic (40%) to mildly pleomorphic (60%), and the cells were smaller. The cells showed a smooth, regular nuclear margin; bland chromatin; and indistinct nucleoli. Indian file arrangement was frequently observed (28%). Nuclear molding (28%) and intranuclear inclusions (16%) were also noted. Intracytoplasmic lumina were seen in occasional cases. Logistic regression analysis was carried out, and a comparison between lobular carcinoma and ductal carcinoma, and borderline and benign lesions was done. Logistic regression analysis of cytomorphologic features showed that cellularity and nuclear margin irregularities were the two most important features to distinguish ILC from IDC. In comparison to borderline lesions, cell dissociation was more common in ILC. The salient cytologic features that helped to distinguish ILC from benign lesions was cell size, cellularity, cell uniformity and chromatin pattern. CONCLUSION: There are overlapping cytologic features between ILC, IDC and borderline breast lesions on FNAC smears. Logistic regression analysis may be helpful in this regard.     

Cytologic features of endometrial papillary serous carcinoma

Endometrial papillary serous carcinoma (EPSC) is an uncommon variant of endometrial carcinoma that histologically resembles ovarian serous carcinoma and has an aggressive clinical course. The cytomorphologic features of 17 patients with histologically confirmed EPSC of the endometrium were reviewed and compared with those of 20 patients with histologically typical endometrial adenocarcinoma (TEC). Preoperative cervicovaginal Papanicolaou smear results were available from 14 of the 17 patients with EPSC; 10 (71%) were positive, 1 (7%) was suspicious and 3 (21%) were negative for malignancy. Initial cervicovaginal smear results were available from all 20 patients with TEC; 7 (35%) were positive, 4 (20%) were atypical or suspicious and 9 (45%) were negative for malignancy. Twelve patients with EPSC had peritoneal washings or fluids examined; seven were positive and five negative. Twelve patients with TEC had peritoneal washings or fluids examined; two (17%) were positive and ten (83%) were negative. The cervicovaginal smears from patients with EPSC revealed numerous large tumor cells (with prominent nucleoli) frequently arranged in papillary clusters with background necrosis and, in two cases, amorphous material suggestive of psammoma bodies. In contrast, the smears of patients with TEC showed small to medium-sized cells with extensive phagocytosis and many background histiocytes. The diagnosis of EPSC should be considered when the cervicovaginal smear contains numerous papillary groups of large tumor cells with macronucleoli but without prominent phagocytosis, especially when structures suggestive of psammoma bodies are present. The peritoneal fluids in these patients are more often positive than in patients with TEC, a finding consistent with the propensity of EPSC to involve peritoneal surfaces.     

Fine needle aspiration cytology of Hodgkin's lymphoma: A cytohistologic correlation study from a cancer center in Kuwait

OBJECTIVE: To assess the diagnostic accuracy offine needle aspiration cytology (FNAC) in the diagnosis of Hodgkin's lymphoma (HL). STUDY DESIGN: We selected all the cases in which a cytologic diagnosis of HL, suggestive of or suspicious for HL, or HL as the prime differential diagnosis was offered on FNAC. These cases were correlated with histopathologic follow-up. Cases of primary HL diagnosed on cytology but without histopathology were excluded from the study. RESULTS: Histopathologic follow-up was available in 46 cases. Of these, 42 were correctly diagnosed as HL, and there was a discorrelation in 4 cases, comprising 3 cases of non-HL (T-cell-rich B-cell lymphoma [TCRBCL]-2, anaplastic large cell lymphoma-1) and 1 case of metastatic carcinoma. Overall accuracy was 91.3%. In 14 cases, the cytologic features were diagnostic ofrecurrence; hence, no histopathologic examination was done. No follow-up was available for the remaining 19 cases, which were excluded from the study. CONCLUSION: FNAC is very useful for rapid and accurate approach to the diagnosis of recurrent and most cases of primary HL. Because of morphologic similarities, it is difficult to differentiate HL from anaplastic large cell lymphoma and TCRBCL on FNAC. It is advisable to request a histopathologic examination in all cases of primary HL.     

Fine needle aspiration cytology of epithelioid angiosarcoma: a case report

BACKGROUND: Malignant vascular tumors are rare. Few studies have described cytomorphologic features of hemangioendothelioma and angiosarcoma on fine needle aspiration cytology (FNAC). Malignant vascular tumor with epithelioid morphology can create diagnostic difficulty, as the cytology may simulate that in other nonvascular malignant tumors. We describe epithelioid angiosarcoma, diagnosed on FNAC, in which a differential diagnosis of histiocytosis and inflammatory granulation tissue was considered. CASE: A 20-year-old man presented with forehead and scalp swellings. The forehead lesion was radiologiocally associated with a lytic lesion in the bone. FNA resulted in high cellular yield, and smears revealed prominent vascular pattern with endothelial cell atypia and histiocytoid/epithelioid neoplastic cells, occasional mitotic figures and a few cells displaying nuclear grooving. Smear background showed a significant number of neutrophils. Epithelioid hemangioendothelioma/angiosarcoma, histiocytosis and inflammatory granulation tissue were considered. A cytologic diagnosis of epithelioid angiosarcoma/epithelioid hemangioendothelioma was suggested and confirmed on histopathologic and immunohistochemical examination. CONCLUSION: Cellular aspirates from malignant epithelioid endothelial tumors involving bone may be cytologically mistaken for histiocytosis and, rarely, inflammatory granulation tissue. However, prominent vascular pattern with striking endothelial cell atypia, presence of mitotic figures and careful search for presence of endothelial differentiation are helpful in accurate cytologic diagnosis.     

Glassy cell carcinoma of the uterine cervix. Cytologic features and expression of estrogen and progesterone receptors

OBJECTIVE: To identify the cytomorphologic features and investigate the expression of estrogen receptor (ER) and progesterone receptor (PR) in glassy cell carcinoma (GCC) of the uterine cervix. STUDY DESIGN: A retrospective analysis of nine GCCs encountered at Korea Cancer Center Hospital between January 1990 and April 1999 was undertaken. The cervical smears were obtained prior to histologic diagnosis of GCC. The cytomorphologic and clinical features were reviewed, and the expression of ER and PR was investigated immunohistochemically on histologic sections. RESULTS: Smears of GCC were hypercellular and remarkably cohesive. The tumor cells were large and characterized by abundant granular cytoplasm, distinct cell membranes and round to polygonal, large nuclei with prominent nucleoli. In the background tumor diathesis and numerous inflammatory cells containing eosinophils were present. The inflammatory cells (mainly eosinophils) were intimately associated with tumor cells to form "granuloepithelial complex." Immunohistochemically, ER was identified in two of the nine cases and PR in one of them. CONCLUSION: Cytology of GCC has characteristic features that differ from those of other carcinomas or atypical reparative cells. Although there are deceptive mimics of GCC, the characteristic cytologic findings should prompt a diagnosis of GCC. ER and PR positivity was found in two cases (22%) and one case (11%), respectively, of GCC, suggesting that this tumor might be hormonally responsive.     

Fine needle aspiration cytology of the Ewing's sarcoma family of tumors

OBJECTIVE: To study the cytomorphologic features of the Ewing's sarcoma (ES) family of tumors. STUDY DESIGN: During a period of eight years (1990-1997), 123 soft tissue tumors and 65 bone tumors were evaluated by fine needle aspiration cytology (FNAC); 14 cases were diagnosed as in the ES family of tumors. The ages of the patients ranged from 8 to 30 years. All the cases were histologically confirmed. RESULTS: Of 14 cases of the ES family of tumors, 7 were ES, 3 extraosseous ES (EOE), 2 peripheral primitive neuroectodermal tumor (PPNET) and 2 Askin tumor. Cytologically, smears from all the cases showed round tumor cells with a high nuclear/cytoplasmic ratio. On detailed examination, subtle differentiating features were observed. The cells in ES had finer nuclear chromatin in comparison to those of PPNET and Askin tumor, and punched-out clear cytoplasmic vacuoles were present. PPNET showed nuclear molding, unipolar cytoplasmic tags and Homer-Wright rosettes. Histologically, all cases of ES and EOE and one case of Askin tumor showed periodic acid-Schiff-positive inclusions. CONCLUSION: FNAC features coupled with clinical findings enable a rapid diagnosis of the ES family of tumors, from which treatment modalities can be determined.     

Cytomorphologic features of Merkel cell carcinoma in fine needle aspiration biopsies. A study of two atypical cases

OBJECTIVE: To report atypical cytomorphologic features in fine needle aspiration biopsies (FNABs) from two cases of Merkel cell carcinoma (MCC), a primary neuroendocrine neoplasm of skin. STUDY DESIGN: Retrospective review of FNABs with histologic correlation from six patients with MCC and a report of findings from two whose smears showed atypical features. RESULTS: Typically the aspirates produce highly cellular smears of loosely clustered and individual, relatively monomorphic, small tumor cells with round to oval, regularly contoured nuclei. In two of our cases, the tumor cell nuclei exhibited a spectrum of pleomorphism ranging from moderately complex nuclear membranes with cleaves, indentations and protrusions in one case to large, markedly bizarre, convoluted nuclei and multinucleate tumor cells in the extreme case. Both cases were primary neoplasms, and the diagnosis was based on clinical, histologic and immunohistochemical data. Additionally, electron microscopy was performed on the tumor with bizarre nuclei and demonstrated rare, dense core neurosecretory granules and paranuclear bundles of intermediate filaments.     

Fine needle aspiration of lymphadenopathy in visceral leishmaniasis

OBJECTIVE: To illustrate the cytomorphologic features of Leishmania lymphadenitis associated with visceral leishmaniasis (V/L) and post-kala-azar dermal leishmaniasis (PKDL) and to highlight the fact that Leishmania lymphadenitis must he included in the differential diagnosis of patients presenting with lymphadenopathy, particularly in areas endemic for the disease. STUDY DESIGN: Fine needle aspiration (FNA) was routinely done in 21 cases of lymphadenopathy in VL (18 cases) and PKDL (3 cases), and the detailed cytomorphologic features were correlated with the respective histopathologic findings. RESULTS: Amastigote forms of Leishman-Donovan (LD) bodies were seen in 19 cases both intracellularly, in histiocytes and multinucleate giant cells, and extracellularly. The FNA smears revealed a polymorphous population of cells composed of lymphocytes, histiocytes, plasma cells, giant cells and tingible body macrophages. In a few cases, epithelioid cell granulomas were also seen. The cytomorphologic features were confirmed and correlated on histopathology. CONCLUSION: Not all lymphadenopathy in VL and PKDL is due to Leishmania lymphadenitis. Demonstration of LD bodies on FNA smears helps with the early diagnosis of VL and PKDL with lymphadenopathy where the diseases are endemic.     

Role of fine needle aspiration cytology in nodular sclerosis variant of Hodgkin's lymphoma

OBJECTIVE: To assess the efficacy of fine needle aspiration cytology (FNAC) in the diagnosis of nodular sclerosis variant of Hodgkin's lymphoma (NSHL) and to analyze cytologic features that could help in subtyping a case of Hodgkin's lymphoma into this variant. STUDY DESIGN: FNAC smears of 18 histopathologically proven cases of NSHL were analyzed for a variety of features. RESULTS: On initial cytologic assessment, 14 of 18 cases were diagnosed as Hodgkin's lymphoma. No further subtyping was performed. In this retrospective analysis it was possible to revise the diagnosis in the remaining 4 cases. Of the various cytologic features analyzed, presence of numerous lacunar-type cells along with fibroblasts and collagenous material were useful pointers toward a diagnosis of nodular sclerosis variant. Fibroblasts were seen in 83.33%, collagenous material in 27.77% and numerous lacunar cells in 77.77%. CONCLUSION: Subtyping of NSHL based on cytologic features alone has been a matter of debate for a long time. Of the various subtypes, nodular sclerosis poses the greatest diagnostic difficulty. Though certain cytologic features may help in suggesting a diagnosis of nodular sclerosis variant, the primary role of fine needle aspiration is to diagnose a case of Hodgkin's lymphoma as such and advise histopathologic examination for further categorization.     

Chondrosarcoma of the proximal femur with myxoid degeneration mistaken for chondromyxoid fibroma in a young adult. A case report

BACKGROUND: Fine needle aspiration cytology (FNAC) is effective in the diagnosis of bone tumors when combined with careful radiologic and clinical evaluation. However, cases where clinical or radiologic findings are atypical or unusual may lead to an erroneous diagnosis. CASE: A 19-year-old male presented with a pain in the left hip area that had been slowly progressive over a 10-month period. Clinical and radiologic findings suggested either giant cell tumor or chondroblastoma. The smeared aspiration specimen showed loosely cohesive, oval to round cells with moderate amounts of pale pink cytoplasm admixed with pinkish-blue, chondromyxoid material. The individual cells contained a single nucleus with evenly distributed, fine chromatin. A few osteoclastic giant cells were scattered in the smears. A cytologic diagnosis of myxoid lesion with a few giant cells, suspicious for chondromyxoid fibroma, was made. The diagnosis of chondrosarcoma was made by subsequent histologic examination. CONCLUSION: Absence of the usual clinicoradiologic features of chondrosarcoma combined with an unusual cytologic presentation in this case led to a misdiagnosis. In most centers, FNAC has achieved undisputed status as a diagnostic tool, and cytologic diagnosis often forms the basis of the therapeutic protocol. However, at some sites FNAC diagnosis is more problematic. Awareness of the limitations and pitfalls of FNAC is just as important as knowledge of the scope of FNAC in bone tumors. Tumors with chondromyxoid features provide particular difficulties.     

Acantholytic cells exfoliated from pemphigus vulgaris of the uterine cervix. A case report

BACKGROUND: Pemphigus vulgaris of the uterine cervix is rare and almost always associated with cutaneous or mucosal lesions elsewhere on the body. Without a history of pemphigus, acantholytic cells in cervical smears may be misdiagnosed as malignant ones. CASE: A 52-year-old female presented with a vaginal discharge, and a routine cervical smear was collected for cytology. The smear displayed atypical cells lying singly and in loose clusters, having vesicular nuclei, a thin nuclear membrane, prominent nucleoli and well-defined cytoplasmic margins. These were labeled atypical glandular cells of undetermined significance, and colposcopic examination and biopsy were advised. On colposcopy vesicular lesions and erosions were noticed on the cervix. The biopsy revealed typical intact as well as denuded suprabasal bullae of pemphigus vulgaris. On reevaluation of the cytologic smear, the cytomorphologic features correlated well with the acantholytic cells of pemphigus. Thorough reexamination of the patient revealed 2 tiny vesicles on the oral mucosa that, on biopsy, confirmed the diagnosis of pemphigus vulgaris. CONCLUSION: Cytopathologists should be aware of the typical cytomorphologic features of pemphigus vulgaris and, in an appropriate clinical setting, should be able to diagnose or at least suspect this entity in even rare sites like the cervix. A false positive diagnosis of malignancy can be avoided if the cytologic findings are judiciously correlated with the history and with clinical and colposcopic examinations.     

Fine needle aspiration cytology of bronchioloalveolar-cell carcinoma of the lung

The fine needle aspiration cytology features of twelve peripherally located bronchioloalveolar cell carcinomas of the lung diagnosed by fine needle aspiration biopsy are described. A spectrum of cytomorphologic changes was appreciated, including classic groups showing uniform malignant cells having prominent depth of focus with a lack of significant nuclear molding. Other cells showed features of atypical alveolar macrophages and bronchial-lining cells. The smears demonstrated malignant cells arranged along alveolar septae and possessing hobnail-shaped nuclei. Two cases had associated psammoma bodies, and one case demonstrated optically clear nuclei in the malignant cells. This series stresses the fine needle aspiration features that aid in the recognition of this specific lung neoplasm and its differentiation from benign reactive pulmonary lesions, other primary lung cancers and metastatic tumors.     

Cutaneous manifestations in non-Hodgkin's lymphoma

OBJECTIVE: To examine and subtype cutaneous lymphoma specimens for diagnosis. STUDY DESIGN: Aspiration smears from skin lesions and lymph nodes diagnosed as non-Hodgkin's lymphoma (NHL) on cytology in 6 cases over a period of 1 year were reviewed. Two were follow-up cases of nodal lymphoma and were receiving chemotherapy, during which they developed skin lesions. In 4, the patients had cutaneous lesions as a presenting manifestation. Cytologic findings were correlated with histologic and hematologic findings and immunocytochemical markers for subtyping. RESULTS: Patients ranged from 14 to 50 years, with equal sex ratio. All presented with 0.5-5 cm multiple nodular, ulcerated and fungating skin lesions at various body sites. The aspirate was satisfactory in all cases. Cytologically, all cases were diagnosed as NHL. They were then immunocytochemistry subtyped as various lymphomas. CONCLUSION: Cutaneous lymphoma should always be considered in the presence of predominantly atypical lymphoid cells in smears from nodular and fungating skin lesions, even in the absence of a definitive clinical diagnosis.
