Carcinoma with Medullary Features of the Nipple: A Case Report of an Infrequent Breast Tumor with a Rare Presentation

Nipple pedunculated tumors are uncommon breast lesions. Normally, when the physician faces a patient with a nipple tumor without any clinical or imaging parenchymal findings, the initial hypothesis should be a benign lesion, such as nipple adenoma or pyogenic granuloma. Carcinomas are often related to alterations in breast parenchyma, apart from Paget disease, which is frequent, associated with eczematous and/or ulcerated lesion.
