Postmenopausal Huge Ovarian Leiomyoma: A Rare Presentation

Ovarian leiomyoma is one of the rare solid tumours of ovary, accounting for 0.5-1% of the benign tumours of the ovary. We report one such case which presented in a postmenopausal woman. The differential diagnosis includes ovarian fibroma. thecoma. cellular fibroma and sclerosing stromal tumour. Masson's trichrome staining helps to distinguish fibrous and smooth muscle components of the lesion and confirms the diagnosis of ovarian leiomyoma. Hence. ovarian leiomyoma should be considered in the differential diagnosis of ovarian spindle cell tumours.
