Herein we describe a rare case of an “orphan” neoplasm arising on an unusual site. During the clinical examination, a mass of 3 cm was found on the left areola of a male patient. It was a solid, sliding on the deep layer, with a bluish color mass; therefore an excisional biopsy was performed. The histopathological diagnosis was nodular malignant hidradenoma. An oncological consulting recommended a surgical radicalization through a radical mastectomy. No adjuvant therapy has been given. The patient is alive with no evidence of disease after one-year follow up.
