Overview

Gynecomastia has been classified by various systems mainly based on surgical management, the severity of gynecomastia, physical appearance, and etiology.

Classification

Different gynecomastia classification systems are:[1][2][3][4][5][6]

Surgical classification of gynecomastia

Classification system Criteria Description
Physical Tissue type
Nydick's Physical
  • Gland limited to the retro areolar region and it does not reach the edge of the areola
  • Gland extends as far as the edge of the areola
  • The increase in gland volume extends beyond the edge of the areola
Tanner's Physical
  • Stage 1: Nipple prominence
  • Stage 2: Mammillary button stage. The breast and the nipple-areola complex are slightly swollen and diameter of the areola increases
  • Stage 3: Further swelling of the breast and areola without separation of their edges
  • Stage 4: Areola and nipple become protrusive and form a secondary protrusion above the breast

Webster's Tissue type

*NAC, nipple-areola complex; IMF, inframammary fold

Classification based on severity

Gynecomastia can be classified on the basis of severity as:

  • Grade I: Minor enlargement with no skin excess
  • Grade II: Moderate enlargement with no skin excess
  • Grade III: Moderate enlargement with skin excess
  • Grade IV: Marked enlargement with skin excess

Classifcation based on etiology
