pubertal gynecomastia
Temporary breast tissue enlargement in adolescent males during normal puberty, typically self-resolving within two years.
Full Definition
Pubertal gynecomastia is a benign condition affecting up to 65% of adolescent males, characterized by unilateral or bilateral breast tissue enlargement during Tanner stages 2-4. The condition results from normal hormonal fluctuations during puberty, particularly the estrogen-to-testosterone ratio. Most cases resolve spontaneously within 6 months to 2 years without intervention. Clinical assessment focuses on distinguishing normal pubertal changes from pathological causes and providing reassurance to patients and families.
Usage
Usage note: Use 'pubertal gynecomastia' rather than simply 'gynecomastia' when referring to the normal developmental variant in adolescent males.
