This is the 79th case of breast myofibroblastoma reported in the literature. This tumor presents a great variety of morphological features, which increase the difficulty of differential diagnosis. The authors report a breast myofibroblastoma diagnosed in a 73-year-old male. The article discusses a bilateral gynecomastia and a palpable right breast well-defined tumor, without calcifications on mammography, which was surgically removed. Macroscopically, a well-circumscribed uncapsulated nodule was seen with lobular arrangement on cut section, and microscopically, a nodule with pushing borders and a connective pseudocapsule was seen. The spindle cells were arranged in fascicular clusters, with focally collagen bundles and a rich reticulinic network stained black with G\u00f6m\u00f6ri impregnation. Immunohistochemically, the tumor cells were marked by vimentin, CD34, desmin, and smooth muscle antigen and did not express cytokeratin, S-100 protein, CD99, CD10, and factor VIII\u2013related antigen. More than 90% of the cells expressed estrogen receptor. No recurrences were reported 2 years after surgical excision. This case is a variant of cellular myofibroblastoma, with a rich reticulinic network and scanty collagen bands.<\/jats:p>","DOI":"10.1177\/1557988312441817","type":"journal-article","created":{"date-parts":[[2012,3,22]],"date-time":"2012-03-22T12:27:21Z","timestamp":1332419241000},"page":"344-348","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Male Breast Cellular Myofibroblastoma With a Rich Reticulinic Network"],"prefix":"10.1177","volume":"6","author":[{"given":"Simona","family":"Gurzu","sequence":"first","affiliation":[{"name":"University of Medicine and Pharmacy, Targu-Mures, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ioan","family":"Jung","sequence":"additional","affiliation":[{"name":"University of Medicine and Pharmacy, Targu-Mures, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,3,19]]},"reference":[{"key":"bibr1-1557988312441817","first-page":"232","volume":"23","author":"Alam F.
