Unilateral Primary Ovarian Leiomyoma With Degeneration Masquerading As Ovarian Malignancy

Primary ovarian leiomyoma is a very rare benign tumour that usually represents an incidental finding at surgery or autopsy. We report a case of 35-year-old hysterectomized lady presenting with a large cystic abdominal lump which was clinically diagnosed as a malignant ovarian mass but proved to be degenerated leiomyoma on histopathology. We briefly discuss rarity and pathogenesis of this case. Key-words Leiomyoma, ovary, degeneration, smooth muscle, immunohistochemistry
