ABSTRACT: Pilomatricoma or calcifying
epithelioma of Malherbe is a rare benign tumor of the skin and/or the subcutaneous
tissue originating from the hair matrix. It is usually seen in children and adolescents,
however a smaller second peak of onset is seen in the elderly. The head, neck, or
upper extremities are the most common anatomical sites of pilomatricomas, being
less frequently seen on the trunk and lower extremities, and very rarely have they
been diagnosed in the breast. Its malignant counterpart, pilomatrix carcinoma, is
rare and found more often in men. Due to its incapacity of regression, treatment
consists of surgical excision. We present the case of a man with a pilomatrixoma
of the breast, presenting as ACR BI-RADS 4, and we review the literature regarding
pilomatrixomas.
