Pilomatricoma, also known as calcifying epithelioma of Malherbe, is an unusual, but not particularly rare tumor. We excised 9 pilomatricomas from 8 patients in the past 11 months. The ages ranged from 6 months to 63 years, most patients were under 30 years old. The male to female ratio was 3:5. Their sizes were smaller than 2㎝, and the duration prior to excision varied from 2 months to 2years. They were more common on the head and upper extremities. Five tumors were normal skin-colored, and the others showed reddish, bluish or yellowish discoloration. Their consistency varied from soft to firm, and even stony hard. They had no characteristic clinical appearance. Pathological findings showed shadow cell masses, together with some of the following features: basophilic cells, transitional cells, foreign body reaction or calcification. The related literatures are reviewed.
