Abstract
- Pilomatricoma, also known as the calcifying epithelioma of Malherbe, is a benign adnexal neoplasm that arises from primitive cells of the hair matrix. It usually appears as a firm, slowly growing dermal or subcutaneous nodule, almost solitary but occasionally multiple. Anetoderma is characterized clinically by discrete, atrophic skin lesions and pathologically by the focal loss of elastic fibers in the dermis. Anetodermic cutaneous changes in the skin overlying a pilomatricoma have been rarely described in the literature. Herein, we report 17-year-old girl who presented with two skin lesions, one of which was a painful nodule with bag-like, wrinkled surface on the left posterior shoulder and the other was asymptomatic deep seated nodule with skin colored surface on the left upper back. The histopathologic examination showed typical findings of pilomatricoma, and anetoderma was associated with tender nodule on the shoulder.
