Abstract
- Pilomatricomas are rare, usually benign and solitary, asymptomatic, calcifying tumors of the hair matrix cell, which mostly appear in the first and second decade of life. However, they may occur in adulthood. The most prevalent sites of pilomatricomas in children are the head and neck but they may occur anywhere. The typical presentation is a firm, slowly enlarging, freely mobile, well-circumscribed subcutaneous nodule, measuring 0.5 to 3 cm in diameter. The tumors are generally solitary, often adherent to overlying skin. Multiple pilomatricoma is relatively rare. Spontaneous regression is never observed, complete surgical excision is a treatment of choice. We present two cases of pilomatricoma arising from the right posterior auricle and the left posterior neck, which were treated with simple excision.
