Gynecomastia is defined as the development of enlarged breast glands in men. It may coexist with hypertrophy of adipose tissue. The condition in which a man develops large breasts due to hypertrophy of adipose tissue without the presence of a mass gland is defined as pseudogynecomastia. Gynecomastia is considered to be a normal condition in men in three situations:
– Neonatal age: Estrogen increase from the mother.
– Adolescence. Estrogen and testosterone imbalance.
– Senile age: Suppression of testosterone production.
At any other age, gynecomastia is considered to be a pathological condition and should be treated as such.
