Abstract

Introduction: Angiomyolipoma is a benign tumor consisting of vascular structures, smooth muscle and adipose tissue. It is most commonly found in the kidneys and more rarely 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 are a result of traumas and HMB-45 antibody negativity and appear more frequently in men. Neither of the cases, except for one presented until today, had cellular atypia; thus, cutaneous angiomyolipomas are considered not to lead to malignant transformation. It is thought that total excision of the mass is indicated in the treatment of cutaneous angiomyolipoma. case report: Our case presented to our clinic with a left preauricular mass which was thought to be a parotid mass after an initial physical examination. The MRI revealed that the mass did not originate from the parotid gland. The fine-needle aspiration biopsy (FNAB) was non-diagnostic and the mass was excised. The pathological examination revealed „angiomyolipoma”.
