A cutaneous angiomyolipoma case mistaken for a parotid mass

Abstract

Angiomyolipoma is a benign tumor consisting of vascular structures, smooth muscle and adipose tissue. It is most commonly found in the kidney and more infrequently in the liver, lung, heart, intestines, nasal cavity, oral cavity and ear. Cutaneous angiomyolipomas are very rare and show some differences with non-cutaneous angiomyolipomas, these are mostly located in the distal extremities and due to trauma, HMB-45 antibody negativity and appear more frequently in men. All cases except one presented until today were observed not to have cellular atypia; thus, cutaneous angiomyolipomas are considered not to perform malign transformation. It is thought that total excision of the mass is adequate in treatment of cutaneous angiomyolipoma. Our case applied to our clinic with a left preauricular mass which was thought to be a parotid mass after initial physical examination. After magnetic resonance imaging (MRI) scan was performed, it was seen that the mass did not originate from parotid gland After the FNAC resulted non-diagnostic, the mass was excised. Pathological examination revealed "angiomyolipoma" diagnosis.
