Gynecomastia is a benign and usually self-limited condition that occurs in 50-60% of boys during early adolescence. Physical examination findings range from discrete, 1- to 3-cm, round, mobile, and usually tender masses located just underneath the areola to diffusely enlarged breasts. If the mass is large or fixed or if a discharge is present, further workup is necessary.

Young men with gynecomastia may often be monitored in the clinic and may be reassured that the condition is self-limited. If the breast enlargement is such that it causes pain, discomfort, or psychological trauma, subcutaneous mastectomies may be performed. Aromatase enzyme inhibitors are being tested for use in shrinking breast tissue in adolescents with gynecomastia, but their widespread use has not been described. [25]
