Multiloculated omental cystic tumor hiding an angioleiomyoma: case report of a rare and atypical presentation and literature review

Angioleiomyoma is a rare benign tumor arising from vascular smooth muscle and generally located in the subcutaneous tissue of the extremities. We reported a rare case of an intra-abdominal localization originating from the small omentum in which progressive growth detected on radiological follow-up indicated surgical excision. Histology documented a cavernous angioleiomuscular tumor with uncertain potential for malignancy. Although angioleiomyoma is described as a benign tumor, the uncertain behavior for malignancy of this case could have led to neoplastic degeneration. Early diagnosis followed by surgical excision of the neoplasia is crucial.
