RESUMO
Angiomyolipoma is a benign tumor, almost exclusively of the kidney, that is often associated with tuberous sclerosis. Cutaneous location is extremely rare. We report a case of cutaneous angiomyolipoma which occurred on the retroauricular area. A 57-year-old man presented with an asymptomatic mass on the retroauricular area. Although the clinical similarity to an epidermal or pilar cyst was striking, the histopathologic picture was distinctive. The tumor was a well-circumscribed subcutaneous mass composed of a mixture of smooth muscle, vascular spaces, and mature fat covered by a thin fibrous membrane.

We report a case of cutaneous angiomyolipoma which occurred on the sole. A 31-year-old man visited our clinic with 1.3 x1.2 cm sized dome-shaped erythematous nodule on the left sole. There were no signs of tuberous sclerosis. Histopathologic examination showed a well-circumscribed subcutaneous nodule composed of an intimate mixture of blood vessel, smooth muscle, and mature fat. We treated it with a total surgical excision.
