Technetium-99m-methylene diphosphonate scintimammography in male breast cancer

Breast cancer in men is a rare disease, representing less than 1% of all breast cancers. Recently, scintimammography with 99mTc-methylene diphosphonate (MDP) has been proposed as an effective method in the differential diagnosis of breast masses. A 67-yr-old man with breast cancer that showed avid accumulation of 99mTc-MDP is presented in this article. Infiltrative ductal carcinoma was demonstrated histopathologically.
