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

## TL;DR

A rare myopericytoma tumor was found in a woman's broad ligament, highlighting the difficulty in diagnosing such uncommon soft-tissue tumors.

## Contribution

This case report adds to the limited literature on myopericytoma in an unusual gynecological location.

## Key findings

- Myopericytoma was diagnosed in a broad ligament mass through histological and immunohistochemical analysis.
- The tumor was benign with no malignant features despite its hypervascular appearance.
- Laparoscopic excision provided a definitive diagnosis and treatment.

## Abstract

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.
