GYNECOMASTIA

Gynecomastia is a unilateral or bilateral benign breast enlargement in a male. It is usually caused by an altered androgen-estrogen balance that favours the estrogen effect. Microscopically, it is characterized by:

  •  Ductal epithelial hyperplasia
  •  Ductal elongation and branching
  •  The proliferation of periductal fibroblasts
  •  Increase in vascularity in the involved tissue
