[Giant scalp mass]

A 55-year-old man was referred to our department with bleeding from a painless tumor located at the left parietal region of the head which had been progressively growing for a period of 2 years. Physical examination showed a fist-sized pediculated mass overlying the left parietal region and the auricle. The partly livid and ulcerated surface of the tumor was interspersed with light-yellow chalky material. The mass was totally excised. Infiltration of the skull was not observed. Histopathological examination led to the diagnosis of a giant pilomatricoma. Pilomatricoma is a rare, benign skin neoplasm that originates from hair matrix cells and is most frequently located in the head and neck region.
