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.     

Pseudotumoral tuberculosis of the uterine cervix. Cytologic presentation

The cytologic presentation of a case of pseudotumoral tuberculosis of the uterine cervix is described. The presence in cervicovaginal smears of epithelioid cells arranged in clusters mixed with Langhans' giant cells was highly suggestive of tuberculosis. This diagnosis was confirmed by the detection of acid-fast bacilli in histologic preparations and cultures from biopsy specimens.     

Cytologic phenomena accompanying uterine cervix electrocoagulation

In the study of cellular and tissue response to electrocoagulation of the uterine cervix, two cytologic phenomena accompanying the delayed healing process were described: the "contact-developed lucid cell" and the "regression field," which were limited to smear samples exhibiting the transitory appearance of abnormal cells after electrocoagulation. While "contact-developed lucid cells," which were firmly attached to abnormal target cell nuclei in a "cell-in-a-cell" pattern, had a variable effect upon subsequent smear scores, the "regression field," which is similar to that described by others during immunologic rejection of kidney transplants, was consistently followed by a shift of the smear score from the dysplasia range to the normal range. We suggest that abnormal cells differentiated during the healing process as well as those present both before and after treatment are subject to an immune rejection induced by uterine cervical electrocoagulation.     

Microglandular hyperplasia of the uterine cervix. Cytologic diagnosis in cervical smears

OBJECTIVE: To identify cytomorphologic features specific to microglandular hyperplasia (MGH) in cervical cytologic smears. STUDY DESIGN: Twenty-four cervical smears from 24 patients obtained before the histologic diagnosis of MGH made on colposcopically directed biopsies during a period of two years (1995-1997) were evaluated. RESULTS: Of cases with MGH, 13/24 (54%) showed the presence of bidimensional or tridimensional cellular clusters made up of cubic or cylindrical glandular cells with vacuolated cytoplasm; cells with dense cytoplasm, basaloid in appearance, corresponding to immature squamous metaplasia; and subcylindrical reserve cells with small, round nuclei and scant cytoplasm. Clusters showed microlumina or fenestrated spaces, preserved polarity and absence of nuclear peripheral dispersion. In the control group these cellular clusters were found in 6/100 (6%). Statistical analysis (chi 2) showed a strong, highly significant association (P < 0.001) of the cytologic parameters selected and the histologic diagnosis of MGH. CONCLUSION: Until now, no specific cytologic parameters were described for MGH. This study underscored the value of cytomorphologic parameters described for typical cellular clusters showing microlumina or fenestrated spaces with shared party walls and an admixture of glandular cells, and immature squamous metaplastic and subcylindrical reserve cells in the cytologic diagnosis of MGH.     

Fine needle aspiration of adenoid cystic carcinoma metastatic to the lung. Cytologic features and differential diagnosis

Two examples of adenoid cystic carcinoma metastatic to the lung, one from a Bartholin's gland and the other from a submandibular gland, were sampled by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with other more common primary small-cell neoplasms of the lung; to determine distinguishing features, we compared the cytomorphology of adenoid cystic carcinoma with well-differentiated adenocarcinoma, small-cell undifferentiated carcinoma and carcinoid tumor of the lung. The differential features distinguishing adenoid cystic carcinoma from these other neoplasms include: (1) tight, globular, honey-comb arrangements of cells lacking true nuclear molding; (2) acellular chunks of basal lamina material, which alone may suggest adenoid carcinoma; and (3) the extension of a solid core of basal lamina material beyond a sievelike cellular meshwork. The morphologic expression of metastatic adenoid cystic carcinoma is so distinctive as to permit a definite diagnosis.     

Malignant lymphoma of the uterine cervix. Cytologic diagnosis of a case with immunocytochemical corroboration

The cytologic findings in a case of primary malignant lymphoma of the uterine cervix initially suggested the presence of a malignant neoplasm. By the use of immunologic methods, the lymphoma cells were shown to possess the nature of B lymphocytes. The need for cytochemical study to make a definitive diagnosis of this rare condition is emphasized. The cytologic findings are compared with those of cytologically similar conditions in the cervix: reticulum-cell sarcoma, chloroma and endometrial stromal sarcoma.     

Cytologic and hormonal findings in a carcinoid tumor of the uterine cervix

A carcinoid tumor of the cervix in a 40-year-old woman was studied by cytology, histology, electron microscopy, immunohistochemistry and hormonal analysis. The preoperative cytologic and histologic findings strongly suggested a carcinoid tumor of the cervix. The serum serotonin level was elevated; immunohistochemical studies demonstrated the presence of serotonin in the cytoplasm of the tumor cells. Following radical hysterectomy, the concentration of serotonin was measured in the excised tumor; it was about 20 times higher than the level seen in normal cervical tissue, confirming that the tumor was a serotonin-secreting carcinoid of the uterine cervix.     

Cytologic criteria of cystic papillary carcinoma of the thyroid

OBJECTIVE: To establish differential cytologic criteria between benign and malignant thyroid cysts. STUDY DESIGN: The study was a retrospective, transverse, analytic, comparative one of 3 groups of patients with nonfunctional thyroid nodules subjected to fine needle aspiration biopsy (FNAB) and surgical resection of the lesions, with histologic study as the diagnostic gold standard. Fifteen cases of cystic papillary carcinomas (group 1) with initial false negative diagnoses, 42 goiters accompanied by cystic degeneration (group 2) and 15 noncystic papillary carcinomas (group 3) were studied. Independent variables were age and sex; dependent variables were the presence of tridimensional fragments, papillae, anisonucleosis, nuclear bars, pseudoinclusions, powdery chromatin, cytoplasmic vacuoles, metaplastic cytoplasm, psammoma bodies, autolysis, multinucleated giant cells, spindle cells, colloid, monolayered laminae and macrophages in FNAB specimens. Statistical analysis was performed by central tendency measures and the chi 2 test. RESULTS: The chi 2 test revealed a statistically significant difference between group 2 and the groups with papillary carcinoma based on the presence of tridimensional fragments, anisonucleosis, nuclear bars, pseudoinclusions, powdery chromatin, cytoplasmic vacuoles, metaplastic cytoplasm and autolysis. CONCLUSION: The above cytologic characteristics must be searched for systematically in the FNAB of every cystic lesion of the thyroid to rule out the presence of cystic papillary thyroid carcinoma and to decrease the rate of false negative results.     

Verrucous carcinoma of the uterine cervix. A case report

The cytohistopathologic features of a verrucous cervical carcinoma are reported. The presence in a cervical smear of two distinct types of dyskaryotic cells, with regularity of size and shape, and of occasional vacuolated cells set in a bright, eosinophilic background should suggest the lesion. With the cytologic suggestion and the typical warty clinical appearance of the tumor, an accurate preoperative diagnosis may be established.     

Adenoid basal lesions of the uterine cervix: evolving terminology and clinicopathological concepts

The epithelial proliferations that are designated adenoid basal carcinoma (ABC) in the current classification from the World Health Organization represent <1% of all cervical malignancies. These lesions may be associated, and occasionally show morphologic transitions with, conventional cervical malignancies. The determination of the precise frequency with which these so-called ABCs show this association is hampered by the inherent selection bias in the reported cases. However, this frequency appears to be substantial (>15%). The biologic course of ABCs that are associated with separate malignancies is largely dependent on the clinicopathologic parameters of the associated malignancies. Morphologically pure lesions, in contrast, have largely been associated with favorable patient outcomes, as none of the 66 reported patients have experienced tumor recurrence, metastases or tumor-associated death, irrespective of the modality of treatment. Although the finding of genome integrated high-risk human papillomavirus (HPV) types and p53 alterations in adenoid basal lesions (ABL) argue in support of their neoplastic nature, we identified no lines evidence that suggest an inherent malignancy for morphologically pure lesions. The finding of morphologic transitions between ABLs and conventional malignancies and shared HPV types in these areas, suggest that ABLs have some malignant potential. However, the precise magnitude of this potential is not readily quantifiable and should not dictate the management of morphologically pure lesions that are entirely evaluable. ABLs continue to occupy a unique position in human oncology in which the term carcinoma (without an in-situ suffix) is applied to a tumor that has not been shown to recur, metastasize or cause death. We concur with a previous proposal that the term ABC should be discarded and replaced with Adenoid Basal Epithelioma (ABE). In our opinion, there is insufficient evidence at present time to expose patients with morphologically pure lesions to the ominous implications – social, psychological, medical, financial – of a "carcinoma" diagnosis. Morphologically impure lesions should not be designated ABC or ABE. Furthermore, given the uncertainties regarding the frequency with which ABE are associated with separate malignancies, we suggest that the ABE designation only be applied when the tumor in question is entirely evaluable e.g in a hysterectomy specimen or in an excisional biopsy with negative margins. Otherwise, the generic designation Adenoid Basal Tumor is preferable. This approach strikes an appropriate balance between the need to prevent over-treatment of pure lesions on one hand, and the need to ensure that the lesions are indeed pure on the other.     

Metastatic spindle-cell carcinoma. Cytologic features and differential diagnosis

Fine needle aspiration biopsies of tumors can yield a variety of spindle cells derived from several types of neoplasms. Among these is a rare lesion known as a "spindle-cell carcinoma" or "pseudosarcoma," which may represent a transformation of a preexisting squamous-cell carcinoma that has been subjected to radiotherapy or solar damage. The cytologic, histologic and ultrastructural features of a case of metastatic spindle-cell carcinoma of the rib subjected to fine needle aspiration are presented, and other spindle-cell tumors that should be considered in the differential diagnosis are discussed.     

Adenocarcinoma of the uterine cervix metastatic from primary stomach cancer. Cytologic findings in six cases

The cytologic features of six cases of stomach cancer metastatic to the uterine cervix are presented. Atypical cells were found in cytology samples from four patients. Fewer atypical cells, larger cellular and nuclear areas, more discrete vacuoles, increased frequencies of thickening of the nuclear membrane and more coarsely granular chromatin patterns were the characteristic cytologic findings of metastatic cervical adenocarcinoma as compared with primary endocervical adenocarcinoma.     

Cytologic features of ciliated adenocarcinoma of the cervix: a case report

BACKGROUND: Ciliation is a normal finding in the endometrium, fallopian tubes and cervix. Because cilia are characteristically lost when malignant tumors arise at these sites, the detection of cilia on light microscopy is frequently used to support a benign diagnosis. Ciliated carcinomas of müllerian duct origin, however, do occur, albeit rarely, and can pose a potential diagnostic difficulty in cytologic specimens. CASE: A woman with a histologically confirmed ciliated adenocarcinoma of the cervix had prior liquid-based cervical cytology showing atypical, ciliated glandular cells that initially raised the diagnostic consideration of tubal metaplasia. A concurrent biopsy, however, revealed focally ciliated adenocarcinoma of the cervix. CONCLUSION: Awareness of the ciliated variant of adenocarcinoma of the cervix is important to avoid overreliance on ciliation as a definitive feature of benignity in cervical cytologic specimens.     

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.
