Giant Nevus Lipomatosus Cutaneous Superficialis on the Buttock

Nevus lipomatosus cutaneous superficialis is a benign hamartoma characterized by the presence of mature ectopic adipocytes in the dermis. Here, we report a case of giant nevus lipomatosus cutaneous superficialis, measuring 24x14cm in diameter, on the buttock. The tumor was resected, and the cutaneous defect was closed with a rotation flap under general anesthesia. No complication or recurrence occurred after surgery. Giant nevus lipomatosus cutaneous superficialis is very rare, and repair of the skin defect required plastic and reconstructive surgery.
