Gynecomastia is a proliferation of the glandular component of the male breast. Gynecomastia is the most common variant condition of the male breast and results from the effect of an altered estrogen-androgen balance on breast tissue or from the increased sensitivity of breast tissue to a normal estrogen level. We experienced a case of macrogynecomastia in a 16-year-old boy who had a normal male phenotype and was treated by reduction mammoplasty with breast tissue removal, which was effective and produced good cosmetic and psychologic results.
