Tell me about pilomatrixoma.
A pilomatrixoma is a benign tumor that is associated with hair follicles. They most often occur on the head or neck, although they can also be found on the arms, torso, or legs. It feels like a small, hard lump under the skin; it is not painful and usually grows pretty slowly. Additionally, most people who develop a pilomatrixoma only have one, although having multiple is possible. They can be removed surgically, at which point they typically do not grow back.
Usually, pilomatrixomas are isolated, but can occur as a symptom of some inherited conditions. Additionally, almost all are benign, but a very small percentage may be malignant.
