Abstract
Pilomatrixoma is a benign subcutaneous tumour arising from the sebaceous glands. Mutation in the CTNNB1 gene is seen, suggesting beta-catenin misregulation may be the cause of pilomatrixoma. The preoperative diagnosis may be improved by the awareness of the fact that pilomatrixoma is a common and benign skin tumour of the head and neck region. It presents as a well-defined mass, which may be firm to hard in consistency, usually attached to the skin, but not to the underlying tissue. The colour of overlying skin appears a reddish-brown tinge, indicating that it could be a case of pilomatrixoma. Here, we report a case of pilomatrixoma of the cheek in a woman along with the CT findings and histopathological appearances. Dental surgeons should consider it as one of the differential diagnosis in superficial head and neck swelling with calcification.
