Resumen:	Nodular mucinosis of the breast (NMB) is a rare entity with only a few cases described in the literature, most of them in young girls. All cases are located in the nipple and areolar area and microscopically consist of a multinodular myxoid mesenchymal proliferation. Bands of sclerotic collagen containing preexisting breast ducts and abundant vascularization are other features typical of NMB. No relation to Carney complex has been reported, and an indolent behavior is the rule in all patients. We present a case of NMB occurring in the nipple of a 46-year-old man and analyze the clinicopathological features of the other cases of NMB reported in the English literature, concluding that two of them most likely correspond to trauma-induced cutaneous focal mucinosis of the mammary areola. Finally, we review diagnostic criteria for NMB and elaborate an ontogenetic hypothesis based on both its morphological resemblance to myofibroblastoma and its immunohistochemical profile.
