We herein report a 57-year-old man afflicted with multiple malignant tumors arising from a giant sebaceous nevus on his left parieto-temporal scalp and neck. The upper eyelid was resected in all layers, and the auricle was resected as well, leaving part of the external auricular cartilage; the parotid gland area was also resected over the parotid fascia. The lost part of the left eyebrow was reconstructed using an anterior forehead skin flap, and the residual defect was covered with skin graft and expanded scalp flap. This is probably the first case report of giant sebaceous nevus associated with three malignancies: sebaceous carcinoma, apocrine adenocarcinoma, and basal cell carcinoma.
