Gynecomastia.

Invasive cancer.

Tuberous breast.

General Discussion: Gynecomastia has a Bimodal distribution (Teen,  Male>40). Causes include puberty, Klinefelter's, cimetidine, Heroin, Digoxin, ESLD, Alcoholic, Marijuana.
Specific Discussion: Although it is unwise to assume pre-teens are not abusing illicit substances it is statistically favored that this boy is undergoing puberty which is causing the unilateral glandular proliferation of subareolar tissue.
