[Myoma of the breast muscle].
A female patient presented with a tumoral lesion of the areola of the left breast; the lesion surrounded the nipple. Histopathologically there was proliferation of smooth muscle fibers of the middle and deep layers of the dermis; the papillary dermis was not affected. Myomas in this site do not present the typical characteristics of other kinds of leiomyomas, including those of the scrotum. Therefore, mamillary muscle myomas should not be considered authentic tumors, but rather smooth muscle hyperplasias.
