Myopericytoma in the Broad Ligament: A Rare Entity at a Rare Site.

Myopericytoma (MPC) is a rare mesenchymal soft-tissue tumor that typically presents as a benign lesion. It is most commonly found on the skin of extremities, with infrequent involvement of deeper structures. Its rarity in visceral locations makes preoperative diagnosis challenging, and its hypervascular nature can raise suspicion of malignancy. We report the case of a perimenopausal woman referred to gynecology for evaluation of an incidental adnexal mass detected during a routine transvaginal ultrasound. Further assessment revealed a highly vascularized broad ligament mass of uncertain origin. Laparoscopic excision was performed, and histological examination identified a mesenchymal tumor without malignant features. Immunohistochemical analysis was crucial and confirmed the diagnosis of a MPC. This case highlights the diagnostic challenge, management, and prognosis of this uncommon entity.
