We define gynecomastia as the enlargement of the mammary gland more than 0.5 cm in diameter in man.

As we have mentioned before, gynecomastia is the presence of glandular tissue under and around the nipple-areola. Fat deposition without glandular proliferation does not involve real gynecomastia.

In most cases, it is diagnosed by palpation in a plastic surgeon’s office. An evaluation of the patients’ history that includes medications and diseases is very basic.

If there is suspicion of malignancy then a mammography is recommended. Moreover, in cases of suspected hormonal disruption a full hormonal control is recommended in which the function of the liver, kidney and thyroid is investigated
