Eccentric

I've never heard of it but you never know.  Best of luck to you.  Especially with the man-o-gram.  Those ladies can be ruthless!

Clinical Features

55). A mass in the upper outer quadrant is the second most common presentation. A slight predilection exists for the left breast in multiple series. Bilateral breast cancer in males is very unusual (<1%) (56). Nipple discharge is a rare presentation of the disease. If serosanguineous or bloody nipple discharge is noted, malignancy should be suspected. Other findings on examination for malignancy include nipple retraction, ulceration of the nipple or skin, fixation to skin or muscle, tumor tenderness, enlarged axillary lymph nodes, or Paget disease (55).

57). Gynecomastia is common, occurring in up to 40% of men without MBC and is seen in an equal proportion of MBC tumor samples (58). Gynecomastia can be unilateral or bilateral symmetric enlargement of the breast with poorly defined borders. On mammography, MBC is usually subareolar and eccentric to the nipple. The lesion is frequently well defined, and calcifications are rarer and coarser than those occurring in female breast cancer (59). In contrast, gynecomastia appears as a round or triangular area of increased density positioned symmetrically in the retroareolar region on mammography. Because of the low incidence of MBC in the general population, there is no role for screening mammography in men.
