GlossaryPilomatricoma

benign skin tumor originating from hair follicle matrix cells

Pilomatricoma, also known as Calcifying Epithelioma of Malherbe or Pilomatrixoma, is a benign skin tumor that originates from hair follicle matrix cells. It typically presents as a firm, painless lump under the skin, often on the face, neck, or arms, and can sometimes become calcified. While it is generally non-cancerous, surgical removal is usually recommended to prevent potential complications.
