Teen boys nipples
Both boys and girls show changes in their breasts at puberty. The areola or area around the nipple increases in size in both sexes but to a lesser extent in boys than in girls. However true breast development is very common in boys and a small amount of breast tissue occurs in more than a third of boys at the stage of mid and late puberty, often moreso on one side than the other which also happens in girls. Such breast changes often cause mild pain or tenderness and may produce a small lump or cyst behind the nipple, just as is happening to your son.
