background: a hemangioma is a rather common benign soft tissue tumor that rarely originates from both the pectoralis muscle and the breast. vascular tumors of the breast, such as benign hemangiomas, are rarely seen in men. case presentation: a 40-year-old man presented with a non-tender palpable right breast mass since 6 months ago. on physical examination, a hard lump was detected in the centr...

breast sarcomas have relatively been rare and accounted for 1% of all primary malignant tumors of the breast. pure and primary chondrosarcoma of the male breast would be an extremely rare tumor. it might arise either from the breast stroma itself, or from underlying bone or cartilage. a 65-year-old man has presented with a rapidly growing breast mass since 5 months. physical examination has est...

background and objective: male breast carcinoma (mbc) is an unusual form of neoplasia, representing 0.7 to 1 percent of all breast cancer cases. usually, the carcinoma affects patients after the sixth decade. the aim of this study was to evaluate the status of estrogen and progesterone receptors (er and pr) and prognostic factors (p53 and her-2/neu) in a series of male patients with breast canc...

introduction: the etiology of male breast cancer is unclear, but hormonal levels may play a role in development of this disease. it seems that the risk of male breast cancer related to increased lifelong exposure to estrogen or reduced androgen. the aim of this study was to investigate the expression of the steroid hormone receptors including estrogen receptor (er) and progesterone receptor (pr...

the male breast cancer (mbc) is a very rare neoplasm which accounts for 0.5-1% of the total cases of breast cancer. bilateral involvement is reported to occur in fewer than 2% of all the diagnosed cases of mbc, and synchronous tumors are very rare. because of its rarity, little is known about mbc etiology, its clinical findings and treatment. most patients present with a painless breast mass. t...

Breast disease most commonly affects females; however, a small percentage of men are also affected. Understandably given its low incidence, awareness of male breast disease is low, particularly among the general population. We searched the Medline database from 1950 onwards using the search terms male, breast, neoplasms and gynaecomastia, and reviewed the conditions associated with male breast ...
