Endodermal sinus tumor of the vagina in children: A report of two cases.

Malignant tumors of the vagina in infants and children are rare, with primary germ cell tumor (endodermal sinus tumor [EST]) being rarer, which carries a dismal prognosis. This tumor is often clinically mistaken as botryoid rhabdomyosarcoma and, on histopathological examination, is often misdiagnosed as clear cell adenocarcinoma. Two cases of EST of the vagina in infants aged 9 and 17 months are reported. Both the patients presented with bleeding per vagina and clinically and by ultrasonography were diagnosed as sarcoma botryoides. Both were diagnosed as primary yolk sac tumors. The serum alfa fetoprotein (AFP) level was 4325 and 9328 ng/ml, respectively. One patient aged 9 months expired 2 months after receiving chemotherapy. The other, aged 17 months, was given chemotherapy followed by surgery with reduction of the AFP levels.

Malignant mixed mullerian tumour of the fallopian tube of heterologous variety--a case report.

A female aged 49 years presented with pain and progressive swelling of right lower abdomen. She was operated upon and gross examination revealed a proliferative growth in the fimbrial end of the right fallopian tube. Microscopically the tumour comprised of adenocarcinoma and component of spindle cell stromal sarcoma with areas of chondrosarcoma as heterologous element. A diagnosis of malignant mixed mullerian tumour of the fallopian tube, clinically FIGO stage III was made, which is extremely rare in available literature.

A study of fine needle aspiration cytology of salivary gland lesions with histopathological corroboration.

The diagnostic utility of fine needle aspiration cytology as initial work up of salivary gland enlargement was assessed in one hundred and eighty-five salivary gland specimens over three years period and corroborated with histopathology, whenever feasible. All smears were evaluated according to cell size, amount of cytoplasm, cytologic atypia and presence of lymphocytes. (a) Variable cytologic appearances of pleomorphic salivary adenoma were observed. (b) Cellular pleomorphic adenoma and adenoid cystic carcinoma showed basaloid cell features. (c) Tumours with intermediate size cells and bland cytology included low grade muco-epidermoid carcinoma and cystic lesions. (d) Warthin's tumour, oncocytoma, salivary duct carcinoma and high grade muco-epidermoid carcinoma revealed large cells and abundant cytoplasm with or without atypia. A major diagnostic categories were inflammatory lesions (n = 7 5), cystic lesions (n = 9), benign tumours (n = 81), malignant neoplasms (n = 1 8) and normal acinar pattern (n = 2). Malignant tumours included muco-epidermoid carcinoma (n = 5), adenoid cystic carcinoma (n = 3), acinic cell carcinoma (n = 2), adenocarcinoma (n= 2), squamous cell carcinoma (n = 1), undifferentiated carcinoma (n= 4) and malignant lymphoma (n = 1). Histopathological correlation was possible in 40% of benign and 80% of malignant neoplasms. The overall sensitivity, specificity and diagnostic accuracy were very high. So it can be concluded that fine needle aspiration cytology can play important role in early diagnosis and subsequent therapeutic planning of salivary gland lesions.
