Indian Journal of Otology 2017 23(3):203-204

Pilomatricoma is a benign skin tumor arising from the outer root sheath cell of the hair follicle that usually present in the head and neck region. Pilomatricoma usually presents as an asymptomatic, solitary, firm or hard, freely mobile, dermal or subcutaneous nodule, and exhibits no fixation to neighboring tissues and has a cartilage-like hardness. The characteristic image findings are reported as well-defined subcutaneous masses with or without visible calcification. Despite these general clinical characteristics, the preoperative diagnosis-based solely on the clinical examination is often difficult because of various manifestations frequently presented by the tumor.
