Mucinous breast carcinoma presenting as Paget's disease of the nipple in a man: A case report

Abstract

Male breast cancer is rare compared to its female counterpart representing less than 1% of cancer in men. Moreover, mucinous carcinoma of the male breast is an extremely rare histological subtype of malignancy. Paget's disease of the nipple is rarely observed in males. Case report. Herein, we describe a unique case of an 86 years old man with mucinous breast cancer presenting as Paget's disease of the nipple. According to the immunohistochemical evaluation the neoplastic cells were positive for estrogen (ER) and progesterone receptors (PR). Conclusion. To our best knowledge this is the first case of mucinous male breast cancer presenting as Paget's disease of the nipple. © 2008 Peschos et al; licensee BioMed Central Ltd.
