CASE REPORT A 67-year-old man with a history of smoking presented with a nasal growth, which had increased in size in the previous 2 months. The physical examination revealed an erythematous violaceous exophytic tumor located in the left nostril, diameter of 3 cm, with an ulcerated and friable surface (Fig. 1). A biopsy was performed, and the histopathological examination showed a superficial and ulcerated fragment of skin. In the dermis, there was a well-vascularized tumoral lesion. The neoplastic cells were epithelioid with a clear vacuolated cytoplasm and slight to moderate pleomorphism (Figs. 2, 3).
