A Rare Neoplasm: Primary Adrenal Leiomyosarcoma.

Adrenal incidentalomas are common neoplasms and while they are often benign, they have the potential to be malignant. The American Urological Association guidelines state that adrenal incidentalomas should be surgically resected if they are large, metabolically active, or display malignant characteristics. Other groups have suggested that growth kinetics be factored in as well. We present a case of an adult woman with adrenal incidentaloma which was subsequently discovered to be a primary adrenal leiomyosarcoma, a rare subtype of soft tissue tumors.
