Pilomatrixoma of the head and neck in children.

Pilomatrixoma is a slow-growing hard mass found beneath the skin. It is most common on the face and neck but sometimes it can be found on the scalp, eyelids and arms. Most cases of pilomatrixoma occur in children under the age of seven and the condition is twice as common in females as in males. The treatment consists of surgical excision. Six patients with confirmed histopathologic diagnosis of pilomatrixoma involving the head and neck areas are reported. Presenting signs and symptoms, lesion characteristics, and treatment rendered are described. The authors review the literature and discuss the guidelines for the diagnosis and surgical management of pilomatrixoma involving the head and neck in children (Fig. 5, Ref. 24).
