[Combined nevus: malignant blue nevus and giant pigmented nevus (author's transl)].

A combined nevus occurring on the right temporal region of a 30-year-old man with multiple giant pigmented nevi on the head, trunk and extremities was surgically removed. Histologically, the cellular blue nevus found in the deep corium fulfilled the criteria of malignancy in so far as mitoses and foci of tumor necroses were present.
