Pigmented skin lesions developed in the postmastectomy scar of a 42-year-old woman, 3 years after mastectomy, clinically mimicking malignant melanoma. A histologic study of the skin showed neoplastic mucin secreting glands and melanocyte colonization. Literature pertaining to melanin pigmentation of epithelial tumors not primary in the skin is reviewed.
