Abstract

Pilomatricoma is a benign skin tumor originated from hair follicle shich outbreaks commonly in any age group. It is more common in infancy and childhood; mainly involving the head; neck and upper extremities as a solitary mass and showing characteristic gradual growth for the period of a few months to a few years. At Dongsan Medical Center; we have experienced two cases of pilomatricoma through pathological diagnosis after removing the tumors in the posterior auricle and submandibular area. Case 1 was a 3 year-old girl who presented a firm tender mass about 2.5 × 2.0 cm in size at the right posterior auricle; and case 2 was a 22 year-old woman who had a firm non-tender mass about 3.0 × 3.0 cm in size at the right submandibular area. Both tumors were solitary nodular and well demarkated from subcutaneous tissue. Both patients underwent excision of the masses under general anesthesia. The tumors showed basaloid cells and ghost cells microscopically and diagnosed as pilomatricoma.
