Alveolar soft part sarcoma (ASPS) of the uterine cervix is a rare malignancy, and 21 cases have been reported the literature from every language (including our case). Herein, we describe a 17-yearold female patient who presented with active vaginal bleeding. Pelvic examination revealed a 1.6 ×1.0×0.5-cm-sized soft mass protruding from the uterine cervix. The final pathological diagnosis was ASPS of the uterine cervix. Immunohistochemically, tumor cells were strongly nuclear positive for transcription factor E3. The patient remained disease free for 24 months without adjuvant therapy. The prognosis of ASPS in the cervix is considerably better than that of ASPS in soft tissues due to early clinical detection, small size, and resectability. ASPS should be considered in the differential diagnosis of an unusual epithelioid neoplasm showing organoid appearance with mild cytologic atypia and no/rare mitotic figures, particularly in young women. Pathologists should be aware of those unusual locations where ASPS may originate.

The fluoroscopy-guided fine needle aspiration biopsy has been gaining widespread acceptance as a rapid and effective method to make a pre-operative diagnosis of mediastinal tumors including thymoma, malignant lymphoma, and metastatic carcinoma. Although thymoma is a most common tumor of the superior mediastinum, most cytopathologists are not experted in cytologic diagnosis of this tumor because of limited experience. In order to define the diagnostic cytologic features of thymoma, we have retrospectively reviewed imprinting smears and corresponding tissue sections from four cases of this tumor.
All cases revealed an apparent biphasic pattern of epithelial cell clusters and lymphocytes with occasional branching capillary fronds extending from three dimensional epithelial cell clusters. Epithelial cell clusters predominated in one case and lymphocytes in two cases. Mixed epithelial cell and lymphocyte type represented in one of four cases.
In the lymphocyte predominant type, the presence of epithelial cell clusters and small mature lymphocytes are helpful features to differentiate from a malignent lymphoma.
Endometrial papillary serous carcinoma (EPSC) is a distinct variant of endometrial adenocarcinoma that histologically resembles ovarian serous papillary adenocarcinoma and has an aggressive clinical course. Usually, the tumor is diagnosed at the advanced stage. The tumor has well confused with metastatic ovarian tumor of identical histology. Diagnosis of EPSC should be considered when the cervico-vaginal smear reveals numerous papillary clusters of tumor cells with macronucleoli and psammoma bodies.
Recently, we have experienced two cases of EPSC diagnosed on cervico-vaginal smears, which revealed characteristic cytologic features including numerous papillary clusters of tumor cells with macronucleoli. The cytologic diagnoses were confirmed on histologic sections.
We studied cervical cytology of 175 cases of histologically confirmed microinvasive squamous cell carcinoma of the uterine cervix in Cheil General Hospital from 1991 to 1993.
Excluding 32 cases of insufficient smear, 143 cases were reviewed in view of background, cellularity, smear pattern, nuclear chromatin and presence of nucleoli. The characteristic findings of microinvasive carcinoma were syncytia and/or individual tumor cells in the focally necrotic inflammatory background. Nuclear chromatin was clear or fine. Nucleoli were observed in 55%. The prediction rate of microinvasive carcinoma was 74%. There is no significant relationship between the cellular features and depth of invasion.
Glassy cell carcinoma is an unusual neoplasm of the uterine cervix that accounts for 1~2% of all cervical malignancy. It is a rapidly progressive and biologically aggressive disease with poor response to therapy. This tumor is considered to be a poorly differentiated mixed adenosquamous carcinoma.
The cytologic findings are characterized by tumor cells arranged predominantly in syncytial like aggregates and an inflammatory background. The tumor cells have moderate amounts of eosinophilic or amphophilic cytoplasm, which is often finely granular. The nuclei are relatively large and have fine chromatin with prominent eosinophilic nucleoli.
Cytologically, glassy cell carcinoma is most likely to be confused with large cell nonkeratinizing squamous cell carcinoma and with atypical reparative cells. Herein, we report three cases of glassy cell carcinoma of the uterine cervix diagnosed by cervicovaginal smear and confirmed by histologic section with review of literatures.
Atypical condyloma is a variant of flat condyloma characterized by the presence of atypical koilocytes having large hyperchromatic, smudged and often bizarre nuclei.
Atypical condyloma can be frequently misdiagnosed on cytologic smear and on tissue sections by its marked cellular atypia, as high grade dysplasia, in situ or even invasive squamous cell carcinoma. We described two cases of atypical condyloma of the female genital tract. The cytologic features and histologic changes were reminiscent of those of invasive squamous cell carcinoma and severe degree of dysplasia of the uterine cervix. The differential findings between atypical condyloma and squamous cell carcinoma were discussed in detail.
