Cutaneous Angiomyolipoma-A Distinct Entity That Should Be Separated From Classic Angiomyolipoma: Complete Review of Existing Cases and Defining Fundamental Features

Cutaneous angiomyolipoma is a rare mesenchymal tumor that is demographically, clinically, and immunohistochemically distinct from its renal and extrarenal counterparts. We present a case of cutaneous angiomyolipoma in the right retroauricular area of a 35-year-old male patient and provide a broad systematic review of the literature and the largest compilation of cutaneous angiomyolipomas reported to date. According to the findings presented in this review, we conclude that cutaneous angiomyolipoma should be completely separated from renal and extrarenal angiomyolipomas and therefore be considered a distinct entity in the classification of skin tumors.

Cutaneous Angiomyolipoma of the Ear: A Case Report and Literature Review

Cutaneous angiomyolipoma is a rare mesenchymal tumor, distinct from its renal counterpart. Only few cases have been reported in English language literature to date. Here, we report a case in a 36-year-old man who presented with a painless swelling on his right ear. Microscopy revealed a well-circumscribed tumor, composed of an admixture of mature adipocytes, blood vessels, and bundles of smooth muscles. The tumor cells were positive for desmin and calponin but negative for HMB45, melan-A, SOX10, tyrosinase, and CD10. We present the case to emphasize the uniqueness of cutaneous angiomyolipoma from its renal counterpart. We also review the relevant literature on this topic.
