The aim of this study was to evaluate the diagnostic value of fine needle aspiration cytology (FNAC) in the assessment of palpable supraclavicular lymph nodes. The material was analysed in 218 cases with enlarged supraclavicular lymph nodes in which FNAC was performed by the conventional method. In all cases cytological examination was performed on-site after staining the smears by the Papanicolaou method. In addition, air-dried smears, fixed smears, filter preparations from needle washings and cell blocks were studied. The FNAC diagnosis was supported by examining cell blocks which added the reliability of histological architecture; further support was obtained by tissue biopsy and/or comparison with the primary tumour in some of the cases. Eleven cases were diagnosed as inflammatory lesions and 41 cases were unsatisfactory because of scanty/acellular samples (despite two to three repeat samplings). However, in five of these, malignant tumours were later found on biopsy, which was done for persistent enlargement of the supraclavicular lymph node(s). Fifty-three cases were diagnosed as negative for malignancy (normal cellular elements, n=15; reactive elements, n=38) and 12 cases were suspicious of malignancy. In 11 cases a diagnosis of lymphoma was made on histology and in 90 cases metastatic tumours were diagnosed. The overall sensitivity was 92.7%, specificity 98.5%, positive predictive value 97.3% and the negative predictive value was 94.8%. Based on our study we feel that FNAC of palpable supraclavicular lymph nodes as a first line of investigation is a cost-effective procedure and is not only useful in the diagnosis of various lesions but can also help in deciding on appropriate management. Furthermore, the histological architecture from cell blocks can be correlated with cytology, and such material can be used for appropriate histochemical and immunomarker studies, which can be useful in enhancing the diagnosis.  相似文献

OBJECTIVE: To elucidate the cytologic characteristics of metastatic papillary thyroid carcinoma (PTC) in cervical lymph nodes and the differences in cervical lymph nodes from those of stage I (intrathyroidal) PTC. STUDY DESIGN: Forty-seven cases of papillary thyroid carcinoma with cervical lymph node metastasis (group A) and 38 cases of intrathyroidal papillary carcinoma (group B) were included in this study. Preoperative fine needle aspiration cytology (FNAC) examination was performed on enlarged cervical lymph nodes (47 cases, group A) and enlarged thyroid nodules (13 cases, group A, and 38 cases, group B). All the cases were surgically excised and pathologically verified. The cytologic smears were reviewed and analyzed. RESULTS: The cytologic characteristics of metastatic PTC in cervical lymph nodes displayed a higher frequency of foamy macrophages (51.1% vs. 26.3%) and a lower frequency of distinct cell borders (38.3% vs. 71.1%) than those of stage I PTC. Metastatic PTC in cervical lymph nodes also had a higher frequency of cystic degeneration (44.7% vs. 5.3%) than intrathyroidal lesions. In 1 of the 47 cases with lymph node metastasis, the aspirate contained macrophages but no tumor cells. CONCLUSION: FNAC was useful in the diagnosis of metastatic PTC in cervical lymph nodes. However, because cystic degeneration appeared frequently, FNAC combined with thyroid ultrasonography to find the primary lesion is necessary in this situation.  相似文献

OBJECTIVE: To evaluate the diagnostic value of needle aspiration cytology (NAC) in the assessment of palpable axillary lymph nodes and determine whether ancillary procedures can be useful in enhancing the diagnosis. STUDY DESIGN: The material was analyzed in 336 cases with enlarged axillary lymph nodes in which NAC were performed by the conventional method. In all cases cytologic examination was done on site after staining the smears with the Papanicolaou method. In addition, air-dried smears, fixed smears, filter preparations from needle washings and cell blocks were studied. The NAC diagnosis was supported by examining cell blocks, which showed the reliability of histologic architecture; further support was obtained with tissue biopsy and/or comparison with the primary tumor in some of the cases. RESULTS: Twelve cases were diagnosed as inflammatory lesions, and 64 were unsatisfactory due to scanty/acellular samples (despite 2-3 repeat samplings). However, in 6 of these, malignant tumors were later found on a biopsy done due to persistent and continued enlargement of an axillary lymph node or nodes. One hundred twenty-two cases were regarded as negative (normal cellular elements, n = 52; reactive elements, n = 70), and 4 cases were suspicious for malignancy. In 124 cases a variety of metastatic tumors were diagnosed (breast, n = 63; melanoma, n = 22; others, n = 39), and in 10 cases a diagnosis of lymphoma was made. CONCLUSION: NAC of palpable axillary lymph nodes as a first-line of investigation is a cost-effective procedure and is not only useful in the diagnosis of various lesions but can also help in deciding on management. Also, histologic architecture from cell blocks can be correlated with cytology, and such material can be used for histochemical and immunomarker studies.  相似文献

BACKGROUND: Skin is an uncommon site for metastatic deposits from internal malignancy. The scalp as a metastatic site is uncommon. Metastatic skin/scalp nodules can be diagnosed accurately by fine needle aspiration cytology (FNAC). However, few reports exist on the FNAC diagnosis of metastatic skin/scalp nodules. Metastatic skin nodules may mimic primary skin tumors, or vice versa, and some primary skin tumors may be mistaken for metastatic skin deposits. CASES: In case 1 a 60-year-old male presented with nodules on the scalp, back and upper extremity. The scalp nodule was noticed first, followed by the ones on the back and upper extremity. FNAC of nodules on the scalp and upper extremities showed deposits of carcinoma. The nodule on the back was excised. In case 2 a 66-year-old female presented with a nodule on the scalp. She also had enlarged bilateral cervical lymph nodes. FNAC of the scalp nodule and cervical lymph nodes revealed the cytologic features of non-Hodgkin's lymphoma. CONCLUSION: Metastatic cutaneous/staneous/subcutaneous deposits can pose diagnostic hurdles in the absence ofprevious or simultaneous malignancy. FNAC is a quick and cost-effective tool for the evaluation of such nodules.  相似文献

OBJECTIVE: The phenomenon of cancer-to-cancer metastasis of cutaneous squamous cell carcinoma (SCC) and chronic lymphocytic leukaemia (CLL)/small lymphocytic lymphoma (SLL) is a rare event and only occasionally documented in the medical literature. METHODS: Two patients with SCC of the skin that were previously treated for CLL are presented. Both had palpable lymph nodes in the neck and fine needle aspiration cytology (FNAC) was performed to evaluate the pathological process. In addition, the literature on cutaneous SCC metastatic to CLL/SLL with special emphasis on the role of FNAC in this specific clinical situation was reviewed. RESULTS: On examination of the FNAC smear, cancer-to-cancer metastasis of cutaneous SCC to lymph node replaced by CLL was found. In one of the patients, light microscopy examination of the smear was complemented by immunostaining of atypical cells with cytokeratin antibodies and immunophenotyping of lymphoid cells by flow cytometry. In addition to our two patients, nine cases of cutaneous SCC metastatic to CLL/SLL have been reported in the literature, and in only one was the diagnosis made by FNAC. CONCLUSION: FNAC supported by ancillary immunocytological techniques could also be used in diagnosis of specific clinical situations such as cancer-to-cancer metastasis of the tandem of SCC-CLL/SLL.  相似文献

Aspirates (n = 163) from 157 patients with enlarged superficial lymph nodes were obtained over a 5-year period in a combined surgical/FNAC clinic. A definitive diagnosis was achieved in over 77% of the cases: benign 52.7%, malignant 25.1%. The diagnostic accuracy was 94.4%, sensitivity 85.4%, and specificity 100%. The false-negative rate was 12.5% but decreased to 3.5% when lymphoma cases were excluded. There were 36 cases of metastatic disease, the majority of which were from a primary breast carcinoma. The main diagnostic difficulty was in distinguishing low-grade lymphoma from reactive hyperplasia. An added advantage was that aspirated material could be used in ancillary tests to help with the differential diagnosis. FNAC has a well-defined role in the investigation of superficial lymphadenopathy. Used in the proper setting it will provide a definitive diagnosis in the majority of cases, especially relating to recurrent malignancy or metastatic disease. Patients with a reactive cytological picture and no clinically suspicious symptoms could be spared unnecessary surgery and reviewed through follow up. This technique is cost-effective, of high diagnostic accuracy, and results in considerable resource savings.  相似文献

Fine needle aspiration cytology (FNAC) in children has been slow to gain acceptance as compared with its use in adults. The aim of this retrospective study is to determine the utility of FNAC in diagnosing paediatric lymphadenopathy. Six hundred and ninety-two paediatric lymph nodes were aspirated during the period from January 1996 to June 2001. Aspirated material in 32 cases (4.6%) was deemed inadequate for cytological diagnosis. In the remaining cases, 62.2% were reactive lymphadenopathy, 25.2% tuberculous lymphadenitis, 6.3% acute suppurative lymphadenitis, nine cases revealed malignancy (seven lymphoma, two metastatic deposits) and one case had Langerhan's cell histiocytosis. No significant complications were encountered in any of the cases. FNAC emerged as a safe and reliable diagnostic procedure in paediatric age group obviating the need for excision biopsy.  相似文献

OBJECTIVE: To analyze cases of palpable cutaneous/ subcutaneous scalp nodules and evaluate the clinical features and role of fine needle aspiration cytology (FNAC) in their diagnosis. STUDY DESIGN: A total of 1,022 cases of metastatic malignancies at various sites were analyzed over a period of two years. FNAC was performed as a routine outpatient procedure for palpable lesions and under ultrasound or computed tomographic guidance for nonpalpable, internal sites. Histologic correlation was done when possible. RESULTS: Eighteen cases were found to be metastatic scalp nodules. The scalp as a metastatic site constituted 1.76% of all metastatic sites, 7.72% of extranodal sites, and 15.3% of extranodal and extrahepatic sites. Of the 18 cases, 7 (38.9%) had primaries in the head and neck region (thyroid, 3; orbit, 1; tonsil, 1; tongue, 1; and parathyroid, 1). Cutaneous/subcutaneous metastasis was encountered in 58 patients, and the 18 cases of scalp metastasis constituted 31.03% of all cutaneous sites. CONCLUSION: Careful examination of the skin on the entire body, with particular attention to the scalp, should be done when a primary internal malignancy or recurrence is suspected. FNAC is a very helpful and cost-effective modality in determining the nature of such lesions.  相似文献

Fine needle aspiration cytology and flow cytometry immunophenotyping of non‐Hodgkin lymphoma: can we do better? Objective: To evaluate the diagnostic efficiency of fine needle aspiration cytology/flow cytometry (FNAC/FC) in the diagnosis and classification of non‐Hodgkin lymphoma (NHL) in a series of 446 cases and to compare the results with those of previous experiences to evaluate whether there had been an improvement in FNAC/FC diagnostic accuracy. Methods: FNAC/FC was used to analyse 446 cases of benign reactive hyperplasia (BRH), NHL and NHL relapse (rNHL) in 362 lymph nodes and 84 extranodal lesions. When a diagnosis of NHL was reached, a classification was attempted combining FC data and cytological features. Sensitivity, specificity and positive and negative predictive values (PPV and NPV) of FNAC/FC in the diagnosis and classification of NHL were calculated and compared with those available in the literature. Results: FNAC/FC provided a diagnosis of NHL and rNHL in 245 cases and of BRH in 188 cases. In nine cases, the diagnosis was ‘suggestive of NHL’ (sNHL) and in four cases was inadequate. Histology and clinical follow‐up confirmed 102 cases of NHL and detected one false positive. In 18 cases of BRH diagnosed by FNAC/FC, histological examination revealed 14 BRH and four NHL (false negatives). All nine cases diagnosed as sNHL were confirmed by histology. Including sNHL cases as false negatives, statistical analysis showed 94.9% sensitivity, 99.4% specificity, 99.6% PPV and 93.4% NPV in the diagnosis of NHL. A specific subtype was diagnosed in 125 cases and confirmed in 67 of 70 cases that had histological biopsies. Statistical analysis did not demonstrate significant improvements between the present series and previous studies either in diagnosis or in classification of NHL. Conclusions: FNAC/FC is a fundamental tool in the diagnosis and classification of NHL but the exiguity of diagnostic material and other technical and clinical limitations will probably continue to limit further improvement of the technique.  相似文献

BACKGROUND: Tumors metastatic to the breast are a rare occurrence. The correct identification is essential as there are divergent management implications. Fine needle aspiration cytology (FNAC) is an effective method of diagnosis when coupled with the judicious use of immunocytochemistry. CASE: A 50-year-old Indian woman presented with a palpable right breast lump that was clinically suspicious for malignancy. There were no contralateral breast masses or palpable axillary lymphadenopathy. There was a history of nephrectomy carried out several years earlier for renal cell carcinoma (RCC). FNAC of the right breast lump yielded malignant epithelioid and occasionally spindled cells within an inflamed background, while immunocytochemistry showed positive reactivity of tumor cellsfor CD10, with negative staining for CK7. The cytologic diagnosis favored a tumor of renal origin. The patient underwent wide central excision of the right breast lump, whereby the diagnosis of metastatic RCC with sarcomatoid features was confirmed. On follow-up, she developed metastases to multiple organ sites and died. CONCLUSION: A high index of suspicion is required in the diagnosis of disease metastatic to the breast. FNAC is a reliable diagnostic tool in the distinction of metastasis from primary malignancy of the breast.  相似文献

BACKGROUND: Malignant pleural effusion in association with mesothelioma, bronchogenic carcinoma and breast carcinoma is common, although less frequently reported with other malignancies. We report a follicular variant of papillary thyroid carcinoma (FVPTC), diagnosed on fine needle aspiration cytology (FNAC) of thyroid and lymph nodes and subsequently proved to have metastasized to the pleural cavity. CASE: A 46-year-old man presented with history of breathlessness, thyroid swelling, pleural effusion and bilateral cervical lymphadenopathy. FNAC of the thyroid swelling and the lymph nodes showed features of FVPTC with cervical lymph node metastasis. Pleural fluid examination led to suspicion of pleural involvement by metastatic deposit, confirmed by subsequent pleural biopsy. CONCLUSION: Thyroid malignancies presenting with pleural effusion are rare. In this case, although pleural fluid cytology suggested involvement of pleura, a definitive diagnosis could be rendered only on pleural biopsy. An ancillary aid, such as immunocytochemistry, could have helped establish pleural involvement on routine pleural fluid cytology alone. This case emphasizes the possible existence of rare cases of FVPTC that may be associated with a dismal prognosis. In our case, initial diagnosis of FVPTC could be made only on correlating FNA features of thyroid aspirate with those of lymph node aspirate.  相似文献

BACKGROUND: Ectopic lesions are rarely encountered. Those that are derived from thyroid, breast, endometrium and salivary glands present with palpable masses that can mimic malignancy. Fine needle aspiration cytology (FNAC) is a practical procedure for the differential diagnosis of such lesions but can reveal surprising images for a cytopathologist. CASES: Three cases of discrete, ectopic lesions at different locations occurred. Case 1 was a 27-year-old woman. Upon diagnosis of a submandibular mass with a diameter of 1 cm, FNAC was performed. The smears showed crowded thyroid follicular cells comprising papillary clusters. A cytologic diagnosis of papillary thyroid lesion was rendered, Histopathology revealed that this lesion was ectopic thyroid tissue with focal chronic thyroiditis. Case 2 was a 38-year-old woman who presented with a painful mass with a diameter of 2.5 cm in the abdominal wall. The patient had undergone cesarean section 3 years earlier. The case was diagnosed on FNAC as low grade malignancy in which an adenocarcinoma/mesenchymal tumor distinction could not be made. The pathologic examination revealed endometriosis. Case 3 was a 31-year old woman who presented with a palpable nodule in the axillary region with a diameter of 1 cm. The patient had given birth 1 month earlier and was nursing. An FNAC diagnosis of lactation ectopic breast tissue was made. The mass disappeared by the end of lactation. CONCLUSION: FNAC of ectopic lesions may prove to be a diagnostic pitfall for cytopathologists. A cytopathologist who encounters a cellularpicturefrom a lesion that is outside the normal anatomic location must use a cautious diagnostic approach. Unless there are clear findings, the cytopathologist must refrain from a diagnosis of malignancy.  相似文献

Background:  Differentiation of hepatocellular carcinoma (HCC) from metastatic carcinoma in liver may be difficult on fine needle aspiration cytology (FNAC), especially when both appear as moderate to poorly differentiated tumours. A panel of immunocytochemical stains is frequently used in case of diagnostic difficulty. Recently, CD10 immunostain with a canalicular staining pattern has been shown to be a specific marker for hepatocytic differentiation.
Objective:  The present study was designed to assess the value of CD10 immunostain in distinguishing HCC from metastatic carcinoma in material obtained by FNAC of liver masses.
Materials and methods:  Formalin-fixed, paraffin-embedded cell blocks of 22 cases (7 cases of HCC and 15 cases of metastatic carcinoma), direct acetone-fixed smears and destained smears of 28 cases (18 cases of HCC and 10 cases of metastatic carcinoma) prepared from FNAC of the liver were immunostained using monoclonal antibody against CD10.
Results:  Seventeen (68%) of twenty-five cases of HCC were positive for CD10 with a canalicular staining pattern. Among them 7 (70%) of 10 cases were well-differentiated HCC and 10 (66%) of 15 cases were moderate to poorly differentiated HCC. Of 25 cases of metastatic carcinoma, four (16%) were positive for CD10 with a cytoplasmic (three cases) and membranous staining (one case) pattern.
Conclusion:  CD10 immunostaining is useful in discriminating HCC and metastatic carcinoma of the liver and is easily applied on cell blocks as well as FNAC smears.  相似文献

OBJECTIVE: To study the frequency of regional lymph node metastasis of soft tissue tumors (STT) and to evaluate the utility of fine needle aspiration cytology (FNAC) as an initial investigative modality. STUDY DESIGN: A prospective and retrospective study of over 6 years (1998-2004) was performed to look for frequency of STT metastasizing to lymph nodes. FNAC of enlarged nodes was performed as a routine outpatient procedure after obtaining complete clinical details. Histopathology and immunohistochemistry were correlated where available. RESULTS: Lymph node enlargement was seen in 23 of 241 patients with STTs, of which 19 cases showed involvement (7.88%), synchronous with primary in 12 cases and metachronous in 7 cases. The most common sites of primary tumor were the lower extremity and head and neck region with involved regional lymph nodes. STTs commonly involving lymph nodes were rhabdomyosarcoma and extraskeletal Ewing's/primitive neuroectodermal tumor (PNET); other rare tumors included malignant granular cell tumor, epithelioid hemangioendothelioma, mediastinal ganglioneuroblastoma, angiosarcoma and epithelioid sarcoma. CONCLUSION: Lymph node aspirates should be examined for alien cells, particularly smears that are paucicellular and demonstrate cystic change. Lymph node metastasis of STT is rare and influences staging, treatment and prognosis. Enlarged regional nodes should be examined with FNAC.  相似文献

Immunochemical demonstration of keratin and vimentin in cytologic aspirates   总被引:1,自引:0,他引:1  
Antibodies to intermediate filament proteins were used to characterize tumor cells present in peritoneal and pleural effusions and in thin needle aspirates from palpable lymph nodes. Metastatic adenocarcinoma cells (breast, ovary, endometrium, cervix, colon and stomach) as well as squamous-cell carcinomas and mesotheliomas stained specifically with antibodies to keratin while mesenchymally derived tumor cells (lymphomas, melanoma, fibrosarcoma and neurofibrosarcoma) were positive only for vimentin. Especially in cases of lymph node aspirates, keratin staining in cells was a direct indication of metastatic carcinoma. Antibodies to these different components of the cytoskeleton can thus be used in cytopathologic diagnosis when a definitive diagnosis cannot be made on the basis of conventional cytologic features.  相似文献

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.  相似文献

OBJECTIVE: To examine the accuracy of fine needle aspiration cytology (FNAC) in the diagnosis of thyroid nodules and compare the inadequacy rates for ultrasound-guided and freehand FNAC. METHODS: A retrospective study of 434 patients with thyroid nodules who underwent diagnostic FNAC over a 2-year period. Cytological diagnoses have been compared with the histological assessment of resection specimens in 69 cases. RESULTS: The inadequacy rate was significantly lower from ultrasound guided FNAC (24/373 cases, 6.4%) than from freehand FNAC (8/61 cases, 13.1%) (P = 0.043). Seventy-six percentage of patients had a non-neoplastic cytological diagnosis and, after multidisciplinary review, the patients were reassured and assigned to clinical follow-up. Sixty-seven patients had a resection for cytological appearances consistent with non-neoplastic disease (n = 34), suspicious of follicular neoplasia (n = 23), or suspicious of malignancy (n = 10), and two patients had resections following inadequate cytology with ultrasound appearances suspicious of a neoplasm. The overall accuracy of FNAC analysis for malignancy was 97.0%, with sensitivity 83.3%, specificity 98.0%, positive predictive value 71.4% and negative predictive value 98.4%. The overall accuracy of FNAC analysis for the prediction of neoplasia was 97.5%, with sensitivity 80.5%, specificity 97.8%, positive predictive value 89.2% and negative predictive value 95.9%. Difficulties in cytological diagnosis were associated with lymphoid infiltrates and with degenerative changes in follicular adenomas. CONCLUSION: Ultrasound-guided FNAC has a significantly lower yield of inadequate aspirates than palpable FNAC. The ability of FNAC to predict neoplasia in 89% patients and to exclude neoplasia in 95.9% patients makes an important contribution to the multidisciplinary assessment of patients.  相似文献

BACKGROUND: Fine needle aspiration cytology (FNAC) is an important technique in the diagnosis of oral and maxillofacial conditions. The purpose of the present paper is to report a case of oral metastasis of breast carcinoma diagnosed by FNAC. CASE: A 45-year-old, black woman was referred for evaluation of symptomatic swelling in the left mandible. The medical history revealed that the patient had undergone extensive surgery to remove a lobular carcinoma. She had finished chemotherapy treatment about 5 months earlier. Due to the main diagnostic considerations of metastatic and inflammatory disease, FNAC was performed. The cytologic picture was consistent with a metastatic glandular neoplasm. CONCLUSION: FNAC is a safe, reliable, cost-effective and easy procedure and sometimes eliminates the need for open biopsy.  相似文献
