The following are the most common symptoms of pilomatrixoma. However, each child may experience symptoms differently. Symptoms may include a small, hard mass beneath the skin of the face, head, neck or arms. The mass is usually less than 3 centimeters in diameter and the skin covering the mass appears normal or may feel firm or hardened. Usually, the mass is painless unless it becomes infected.
The symptoms of pilomatrixoma may resemble other neck masses or medical problems. Always consult your child's doctor for a diagnosis.
