Management of Gynecomastia and Male Benign Diseases.

Gynecomastia is a common benign breast disease involving abnormally increased mammary gland tissue that can affect men of all ages. It is usually due to a hormonal imbalance without a definitive underlying cause (idiopathic), or secondary to medications/drugs, systemic disorders, or malignancy. Gynecomastia is often self-limiting, and its management is watchful waiting. Other male benign breast diseases, such as cysts, lipomas, seromas, infections, and pseudoangiomatous stromal hyperplasia, should be worked up in a similar manner and often require surgical drainage or excision.
