Abstract

A collision tumor is a combination of two types of district tumors in a single lesion. They are rare but well-documented. This diagnosis is often incidental and their behaviors remain widely unknown. They rarely occur in the skin. This is a case of collision tumor of the skin in a female patient with albinism. The tumor consists of squamous cell carcinoma and basal cell carcinoma of the forehead.
There are no known documented cases of collision tumors of the skin in a patient with albinism.
