A case of virilising steroid cell tumour of ovary.

A middle aged female patient presented to our Gynaec OPD with acute onset of virilising symptoms and vague abdominal pain. The patient’s biochemical values were normal except for a raised serum testosterone level and a raised CA125 level. Ultrasound and Computed tomography revealed an ovarian mass with mild ascites that appeared to be a yellowish solid ovarian tumour on gross examination. Microscopic examination showed a neoplasm composed of medium sized cells with clear cytoplasm and some with eosinophilic granular cytoplasm. The diagnosis of Benign steroid cell tumour of ovary, not otherwise specified (NOS-type) was made. The case is presented for its rarity.
