Adenomatoid tumor of uterus: A rare Leiomyoma mimicker
The present case has been reported in the The Journal of Obstetrics and Gynecology of India.

A 33-year-old woman presented with a bad obstetric history of two abortions. An ultrasound scan revealed a 4 X 4 cm circumscribed echogenic mass in the myometrium, consistent with a fibroid. (Fig.1) The pre-operative investigation was normal.

At laparotomy, a probable degenerated fibroid grey-white, friable with variable consistency, measuring 5X4X2 cm was removed. The postoperative period was uneventful. Histology Sections revealed a lesion composed of variably sized tubules and fenestrated channels arranged in a variably fibrous stroma with congested vascular spaces.

Tubular structures are lined by either plump epithelioid cells with abundant eosinophilic cytoplasm to flattened cell resembling endothelial cells. Signet-ring like cells with apparent intracytoplasmic lumina are seen. Few inflammatory cells are seen in between. On immunohistochemical staining cells were reactive for cytokeratin and vimentin showing its mesothelial origin. Ki-67 index was very low.
