Discussion: pilomatrixoma is defined as one of the most frequent tumors in the cervicofacial area in pediatric age. Surgical removal is the treatment of choice and the recurrence rate is minimal. Conclusions: it is necessary to know pilomatrixoma as a frequent pediatric tumor in the head and neck area.
