Four Cases of Secondary Anetoderma due to Pilomatricoma / 대한피부과학회지

ABSTRACT

Anetoderma is characterized by atrophic patches located mainly on the upper trunk. Secondary anetoderma occurs in the courses of various diseases, such as syphilis, lupus erythematosus, and leprosy. Among them secondary anetoderma due to pilomatricoma is rare and has a characteristic skin manifestation such as scrotal skin or round striae. Herein we report four cases of pilomatricomas with secondary anetodermic cutaneous changes. The overlying skin appeared variously as a pinkish, wrinkled, bag-like bulged, or scar-like atrophic surface. However the histopathologic examination showed commonly a prominent decrease of elastic fibers in the dermis overlying the pilomatricoma mass.
