In pseudogynecomastia, a condition that occurs in obese men, there is only fat deposition, found in the subareolar area. This is not pathologic or physiologic. Patients with pseudogynecomastia typically have bilateral deposition of fat, and, over time, these deposits do not change in shape or size unless a significant increase in aromatization occurs in the fatty tissue, leading to true gynecomastia. A careful history may reveal that the lesions have remained unchanged over a span of several years. If mammography demonstrates no evidence of malignancy, a treatment option would be observation alone.
