Cutaneous Angiomyolipoma of the Ear: A Rare Diagnostic Challenge.

Cutaneous angiomyolipoma is an extremally rare mesenchymal tumor, distinct from its renal counterpart. We describe two patients with cutaneous angiomyolipoma of the earlobe, all of which were clinically misdiagnosed and mistreated as epidermoid cysts, to highlight the need to consider a broad spectrum of differential diagnoses when evaluating any nodular or cystic tumor of the ear. We also provide a comprehensive literature review about this cutaneous entity.
