Gynecomastia Versus Pseudogynecomastia

Gynecomastia is defined as a benign enlargement of the male breast resulting from a proliferation of the glandular component of the breast.Gynecomastia can clinically be detected by the presence of a rubbery or firm mass extending concentrically from the nipples.
Although gynecomastia is usually bilateral, it can be unilateral.

Pseudogynecomastia ( also called lipomastia ) is characterized by fat deposition without glandular proliferation.

You can differentiate between true gynecomastia and pseudogynecomastia by a simple test made clinically by having the patient lie on his back with his hands behind his head. The examiner doctor then places a thumb on each side of the breast, and slowly brings the thumbs together. In true gynecomastia, a ridge of glandular tissue will be felt that is symmetrical to the nipple-areolar complex. With pseudogynecomastia, the fingers won't meet until they reach the nipple.
