Background: Vaginal leiomyoma is an extremely rare benign tumor with only few cases reported so far. It usually arises from smooth muscle cells in sub-epithelial layer of vagina. Its variable presentations can often be confused with other benign or malignant vaginal masses. Case Report: A 40-year-old female, parity 4 living 4, reported to the gynaecology casualty with complaints of frequent menses for 3 years and urinary retention for 2 days. Pelvic examination revealed a mass of around 10×6 cm originating from the left lateral vaginal wall. Histopathological examination of the enucleated mass revealed vaginal leiomyoma. Conclusion: Although vaginal leiomyoma on lateral vaginal wall is a rare entity, it should be included in one of the differential diagnosis of vaginal masses.
