Background
Adenoid cystic carcinoma (ACC) and adenoid basal carcinoma (ABC) are rare in the uterine cervix. ACC is more aggressive than ABC, thus accurate differential diagnosis is important. In this study, we identified cytologic features useful in distinguishing these two tumors for diagnosis. Methods: Three cases of ACC and five cases of ABC were selected for this study. Cervicovaginal smear slides were reviewed retrospectively, and the area, circumference, major axis, and minor axis of nuclei were measured using an image analyzer. Results: ACC displayed three-dimensional clusters with a small acini pattern. ABC displayed peripheral palisading without an acini pattern. The nuclei of ACC were more irregular and angulated than those of ABC, and the former showed a coarsely granular chromatin pattern. The nucleic area, circumference, major axis, and minor axis were 18.556±8.665 µm², 23.320±11.412 µm, 5.664±1.537 µm, and 4.127±1.107 µm in ACC and 11.017±4.440 µm², 15.920±5.664 µm, 4.612±1.025 µm, and 3.088±0.762 µm in the cases of ABC. All measured values showed statistically significant difference (p < .001). Conclusions: Although the nuclei of both of these tumor types were oval shaped, inferred from the ratio of minor axis to major axis (0.728 in ACC and 0.669 in ABC), the area of nuclei was approximately 1.7 times larger in ACC than in ABC. Distinguishing nucleic features, including area, morphology, and chromatin pattern, may be helpful in making a correct diagnosis.

Abstract PDF

Well-differentiated papillary mesothelioma is an uncommon tumor of the testes that usually presents as a hydrocele. Here, we present the case of one patient who did not have a history of asbestos exposure. The tumor was localized in the tunica vaginalis and was composed of three pedunculated masses macroscopically. Microscopically, branching papillary structures with focal coagulative necrosis were present. In addition to immunohistochemistry, simian virus 40 DNA was also tested by polymerase chain reaction. This report presents one case of this rare entity, its clinical and macroscopic features, and follow-up results.

Abstract PDF

Background

The objective of this study was to evaluate a newly-developed EASYPREP liquid-based cytology method in cervicovaginal specimens and compare it with SurePath.

Methods

Cervicovaginal specimens were prospectively collected from 1,000 patients with EASYPREP and SurePath. The specimens were first collected by brushing for SurePath and second for EASYPREP. The specimens of both methods were diagnosed according to the Bethesda System. Additionally, we performed to REBA HPV-ID genotyping and sequencing analysis for human papillomavirus (HPV) on 249 specimens.

Results

EASYPREP and SurePath showed even distribution of cells and were equal in cellularity and staining quality. The diagnostic agreement between the two methods was 96.5%. Based on the standard of SurePath, the sensitivity, specificity, positive predictive value, and negative predictive value of EASYPREP were 90.7%, 99.2%, 94.8%, and 98.5%, respectively. The positivity of REBA HPV-ID was 49.4% and 95.1% in normal and abnormal cytological samples, respectively. The result of REBA HPV-ID had high concordance with sequencing analysis.

Conclusions

EASYPREP provided comparable results to SurePath in the diagnosis and staining quality of cytology examinations and in HPV testing with REBA HPV-ID. EASYPREP could be another LBC method choice for the cervicovaginal specimens. Additionally, REBA HPV-ID may be a useful method for HPV genotyping.

Abstract PDF

Fibroepithelial stromal polyp (FSP) is a benign lesion that can occur at various sites, including the lower female genital tract. In rare cases, however, it may exhibit hypercellularity, bizarre cytomorphological features, and atypical mitoses resulting in an overdiagnosis as a malignant tumor despite its benign clinical course. Recently, we experienced one case of a 30-year-old pregnant woman with cellular pseudosarcomatous FSP that was initially diagnosed as a malignant fibrous histiocytoma at a primary clinic. In addition to describing the rare features of this case, we wish to increase awareness about this benign lesion which will be essential for avoiding unnecessary radical surgery or chemoradiation treatment.

Abstract PDF: A case of primary non-clear-cell adenocarcinoma of the vagina is reported occurring in a 65-year-old woman without exposure to diethylstilbestrol(DES) in utero. The adenocarcinoma did not appear to be associated with vaginal adenosis. It lacked clear cell component and interestingly composed of columnar epithelial cells of endocervical-type Cytologically round to oval unclei revealed one or more small nucleoli and fine granular chromatin pattern. Cytoplasm was pulmp, faintly basophilic and homogeneously stained. Histologically well differentiated columnar epithelial cells were arranged in trabecular pattern mainly, and also occasional glandular lumina and small solid sheets were found. Mitoses were hardly found.

Abstract PDF: We report a case of spindle cell epithelioma, a so-called benign mixed tumor of the vagina. The patient was a 35-year-old nulliparous woman who presented with a polypoid mass in the posterior wall of the lower vagina just above the hymenal ring. The tumor was relatively well-defined with an expansile margin and composed of stromal-type spindle cells with a myxoid stroma arranged in short fascicles and an irregular cord-like or reticular pattern. A few glandular structures lined by cuboidal cells with squamous metaplasia were also noted. Cellular atypia was not conspicuous and mitosis was not found. We examined this tumor immunohistochemically to identify the histogenesis. The coexpression of epithelial and mesenchymal markers in stromal-type spindle cells suggested a multipotential cell origin for this tumor. The patient has been well with no signs of recurrence during the 12 months after surgery.

Abstract PDF

BACKGROUND
We examined cervicovaginal smears that contained definite low-grade squamous intraepithelial lesion (LSIL) cells and rare atypical cells suggestive of high-grade SIL (HSIL) (ASC-H) or contained borderline dysplastic cells between LSIL and HSIL. Such lesions were classified as LSIL-H. This study aimed to investigate the cytologic and histologic characteristics of LSIL-H category and we evaluated the associated clinical risk.
METHODS
The histologic outcomes of LSIL-H were compared with those of LSIL and ASC-H. Both the cytologic and histologic findings of LSIL-H that were confirmed as cervical intraepithelial neoplasia 2 (CIN2) or greater (CIN2+) were investigated.
RESULTS
LSIL-H accounted for 0.09% of the Pap tests. On the follow-up histology, the most frequent outcome was CIN2, and the risk of CIN2+ was higher than that for ASC-H. In the cases of LSIL-H that was histologically confirmed as CIN2+, most of the atypical cells suggestive of HSIL were cytologically similar to those of CIN2, and the corresponding cervical tissues were characterized by small CIN2+ lesions in a large background of flat condyloma/CIN1. The LSIL-H cases not confirmed on initial colposcopically-directed biopsy required further follow-up.
CONCLUSIONS
LSIL-H may be a valid diagnostic category with distinctive features that are different from LSIL or ASC-H. LSIL-H needs further follow-up for the proper management.

Abstract PDF

Enterobius vermicularis is one of the most common parasites found in the intestine of humans. The gravid female worms migrate outside the anus to release eggs on the perianal skin. Rarely, they migrate to the genitourinary tract in female patients. We present a case in which pinworm eggs were found in a cervicovaginal smear of a 37-year-old woman. The eggs were elongated oval shaped and flattened on one side. The thick, double contoured birefringent shell stained bright yellow or orange. Some coarsely granular embryos or curved larvae were enclosed in the refractile shell. Empty eggs or wrinkled shells with clumped granular material were also present. Although pinworm eggs are easily identified because of their characteristic morphologic appearance, careful screening is needed due to the frequent masking by inflammatory cells.

Abstract PDF: Malakoplakia is an uncommon chronic granulomatous inflammation that usually involves the urinary and gastrointestinal tracts, but rarely affects the female genital tract. We experienced a case of malakoplakia in a cervicovaginal smear in a 54-year-old woman. Colposcopic examination showed a friable, easily bleeding tissue in the uterine cervix and the vaginal fornix. The cervicovaginal smear consisted of numerous isolated histiocytes, polymorphonuclear leukocytes, lymphocytes, and plasma cells. The histiocytes had an abundant, granular, and degenerated cytoplasm with inflammatory cell debris. Michaelis-Gutmann bodies were readily identified.

Abstract PDF

We evaluated the usefulness of cervicovaginal cytology as a primary screening test by analyzing the cytologic and histological diagnoses of 2,254 women. Cervicovaginal cytology had 93.0% sensitivity, 86.1% specificity, 88.2% positive predictive value, and 91.7% of negative predictive value. Cervicovaginal cytology as a primary screening test showed much higher specificity but slightly lower sensitivity than HPV DNA testing. However, the sensitivity of cervicovaginal cytology will be improved continuously due to the development of liquid-based cytology. We regard cervicovaginal cytology as a good primary screening test for cervical intraepithelial neoplasia or carcinoma.

Abstract: A case of fibroepithelial polyp with stromal atypia in a 25-year-old female is described. The tumor arose from the vaginal wall and measured 3.5 cm in maximal diameter. It was composed of hypercellular connective tissue stroma and focal myxoid area containing numerous atypical mono- and multinucleated stromal cells. These cells may mislead to make a diagnosis of sarcoma, particulary of botryoid rhabdomyosarcoma.

Abstract PDF: Superficial endometriosis of the uterine cervix refers to a lesion in which endometrial stroma and/or gland is located immediately subjacent to the surface epithelium. The cells on the cervicovaginal smear shed from the lesion can be a significant source of atypical glandular cells of undetermined significance (AGUS), or can be easily mistaken for glandular dysplasia or adenocarcinoma in situ. Not infrequently it occurs at the conization site for cervical neoplasia. We describe the cytologic and histologic features of 2 cases of superficial endometriosis of the uterine cervix, which were discovered during an evaluation for AGUS detected on the cervicovaginal smears, with an emphasis on the utility of trichrome and reticulin staining for the diagnosis of superficial endometriosis. The cervicovaginal smears show sheets and clusters of glandular cells having mild to moderately pleomorphic oval nuclei with inconspicuous nucleoli and indistinct cytoplasmic border. Single cells or tumor diathesis were not present. Diagnostic histologic findings were the absence of thick or abundant collagen bundles, the encasement of individual stromal cells by a fine reticulin network and thick reticulin fibers around the spiral arterioles within the endometriotic foci. Therefore, superficial endometriosis should be considered as a potential source of AGUS, especially during follow-up after conization for cervical intraepithelial neoplasia.

Abstract PDF: 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.
