RESUMEN

Pure ovarian choriocarcinoma is extremely rare and can develop as a germ cell tumor or as a metastasis from uterine or tubal gestational choriocarcinoma or rarely from an ovarian pregnancy. The cytomorphologic findings have been reported previously in different sites. However, this is the first case of pure ovarian choriocarcinoma diagnosed on cytology to the best of our knowledge. The distinction between a gestational and nongestational choriocarcinoma is difficult. A 19-year-old female patient presented with an irregular per-vaginal bleeding and a mass in lower abdomen. Fine needle aspiration cytology smears of the mass were hypocellular and showed large, multinucleated giant cells and malignant mononucleated cells. Background was hemorrhagic. Serum β hCG level was 3,80,000 mIU/ml. A diagnosis of choriocarcinoma was offered which was later confirmed by histopathology. The diagnosis of choriocarcinoma on fine needle aspiration cytology is based on the presence of large, multinucleated giant cells and malignant mononucleated cells. A high index of suspicion should be maintained and estimation of serum β hCG plays a key role in supporting the diagnosis.

RESUMEN

Primary oral malignant melanomas are rare with an incidence of .2 to 8% of all melanomas. Less than 1% of them arise on buccal mucosa. Grossly they arise as a black macule with irregular borders & are commonly of mucosal lentiginous type. They appear at a higher stage and are aggressive with a 5 yr survival rate of 10-25%. 39% of metastasis in thyroid occur from skin (melanomas) and melanomas produce a thyroid mass while the original source remains occult. We report a case of oral malignant melanoma of left buccal mucosa for its rarity and its spread to cervical lymph nodes and thyroid.

RESUMEN

A case of leiomyosarcoma of the scrotum is reported for its rarity. The tumor measured 6.2 x 4 x 4 cm and presented as a gradually increasing painless mass of 1 month duration. Light microscopy showed the typical interlacing fascicles of neoplastic cells with mitotic count of 1-2 / 10 HPF in different areas. Immunoperoxidase stains of vimentin & desmin and electron microscopy confirmed its muscle origin.
