Pigmented paget disease of the breast nipple with underlying infiltrating carcinoma: a case report and review of the literature

Abstract

Paget disease of the breast represents a cutaneous manifestation of an underlying breast malignancy. The rare finding of a pigmented Paget disease mimicking melanoma represents a diagnostic problem. We report a case of a pigmented lesion involving the breast nipple with an underlying infiltrating breast carcinoma, and we describe the clinical presentation, histological findings, and immunohistochemical features with a review of reported cases.
