gynecomastia
Pronunciation: guy-neh-ko-MAS-tee-ah
Benign enlargement of breast tissue in males, commonly occurring during puberty due to hormonal fluctuations.
Full Definition
Gynecomastia is the non-malignant enlargement of breast tissue in males, most commonly observed during adolescence due to the normal hormonal changes of puberty. This condition occurs when there is an imbalance between estrogen and testosterone levels, leading to breast tissue growth. Pubertal gynecomastia typically appears between ages 10-14 and often resolves spontaneously within 1-2 years. However, persistent or severe cases may require evaluation to rule out underlying pathological causes such as hormone-producing tumors, medications, or genetic conditions. The condition can cause significant psychological distress in adolescent males, making appropriate counseling and reassurance important components of care.
Usage
Usage note: Distinguish from 'pseudogynecomastia' which is breast enlargement due to fat rather than glandular tissue.
