Abstract

Pilomatrixoma is an uncommon tumor arising from hair follicles. Commonly occur in children and most frequently in the head and neck region. It can be mistaken for parotid gland tumor, dermoid cyst, or epider-moid cyst, especially when large lesions develop over the periauricular area, difficulty discerning them from lesion developing within the superficial lobe of the parotid gland may occur. We experienced two cases of pilomatrixomas mimicking parotid gland tumor. Although their histologic appearance is characteristic, they may be clinically misdiagnosed. However, combining clinical information with the distinct histologic features should lead to the correct diagnosis.

Key Words: Pilomatrixoma, Parotid gland tumor
