Pilomatricoma: Case Report

ABSTRACT

Pilomatricoma is a rare benign neoplasm arising from hair follicular matrix cells and exhibiting slow growth. The radiologic features of this neoplasm have rarely been described in the literature; in particular, the ultrasonographic findings have not been published in Korea. We report a case of pilomatricoma presenting as a well-marginated soft tissue mass with calcification in the dermis and with overlying bullous skin, a rare clinical variant.
