Paget's Disease of the Male Breast

ABSTRACT

Paget's disease of the breast occurs almost exclusively in women, and is characterized by a unilateral, sharply defined eczematous skin lesion caused by epidermal metastases from underlying ductal adenocarcinoma of the breast. Paget's disease of the male breast is extremely rare. A 61-year-old patient had a skin lesion on the right nipple for 1 year. The lesion was a well defined, brownish, crusted, and keratotic papule, and was associated with an underlying walnut sized, fixed, hard mass and a palpable ipsilateral axillary lymph node. Histologic findings were consistent with Paget's disease. Results of immunoperoxidase staining technigues for S-100 protein and carcinoembryonic antigen were negative. After a modified radical mastectomy and chemotherapy, the patient has been in remission for 12 months.
