Clinical Findings and Therapy of Ureteral Duplication in 61 Children

Osteoclast-like giant cell tumor of the liver is an extremely rare malignancy with poor prognosis. To our knowledge, 5 cases have been reported in English literatures, but there was no report about fine needle aspiration cytologic(FNAC) features. We experienced a case of osteoclast-like giant cell tumor of the liver obtained by computed tomography(CT)-guided FNAC and needle biopsy. The cytologic findings mimicked giant cell tumor of the bone. A large hepatic mass of the left lobe with abdominal wall invasion was found by CT in a 46- year-old female complaining of epigastric pain. The FNAC showed moderately cellular smears consisting of osteoclast-like giant cells and mononuclear cells, which were individually scattered or intermingled in clusters. The osteoclast-like giant cells had abundant cytoplasms and multiple small round nuclei with fine chromatin and distinct nucleoli. The mononuclear cells had moderate amount of cytoplasm and relatively bland-looking oval nuclei with single small nucleoli. All of the cytologic features recapitulated the histologic findings of bland-looking osteoclast-like multinucleated giant cells evenly dispersed throughout the background of mononuclear cell. The immunohistochemical study showed positive reaction for CD68 and vimentin, but negative for cytokeratin in both osteoclast-like giant cells and mononuclear cells.

Four Cases of Autosomal Recessive Polycystic Kidney Disease

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. Dignosis 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.

Cytologic Features of Malignant Lymphoma of the Uterine Cervix: A case report / 대한세포병리학회지

The uterine cervix is an uncommon site of primary non-Hodgkin's lymphoma (NHL). Although the cytologic findings of NHLs are well known, most cervicovaginal smear of uterine NHLs give lower diagnostic yield than common epithelial malignancy because abnormal cells do not appear in the sample in the absence of surface ulceration. Herein, we describe cytologic findings of a case of uterine cervical NHL which was initially diagnosed by cervicovaginal smear. The tumor cells were relatively uniform, isolated, large-sized with scanty cytoplasm and round or indented nuclei. The nuclei had stippled chromatin and small nucleoli. Histologically and immunohistochemically the tumor was proven to be large cell lymphoma of T-cell lineage.

Curschmann's spirals in cervico-vaginal smears / 대한세포병리학회지

Curschmann' spirals morphologically similar to those seen in sputum were found in cervico-vaginal smears of six patients ranged from 28 to 40 years of age, during 18 months from January. 1985 to June. 1986. The prevalence was 1 in 2147 smears in that period. All of them had gynecologic disorders without systemic effect such as chronic cervictis in three, leiomyoma in one, pelvic inflammatory disorder in one, and primary infertility in one. The Curshmann' spirals in the smear showed varying degrees of maturation from wavy incipient ones to highly coiled mature ones, admixed with thick mucinous background, suggesting of their production in the uterine cervix itself. Also the recent history of undergone cryocautery, electrocautery or parturition suggest its production in the endocervical gland due to mechanical obstruction and/or change in biochemical composition of mucus.
