|Other names||Lipomastia, fatty breasts|
|A male with probable comorbid gynecomastia and pseudogynecomastia.|
Adipomastia, also known colloquially as fatty breasts, is a condition defined as an excess of skin and adipose tissue in the breasts without true breast glandular tissue. It is commonly present in men with obesity, and is particularly apparent in men who have undergone massive weight loss. A related/synonymous term is pseudogynecomastia. The condition is different and should be distinguished from gynecomastia ("women's breasts"), which involves true glandular breast development in a male. The two conditions can usually be distinguished easily by palpation to check for the presence of glandular tissue. Another difference between the conditions is that breast pain/tenderness does not occur in pseudogynecomastia. Sometimes, gynecomastia and pseudogynecomastia are present together; this is related to the fact that fat tissue expresses aromatase, the enzyme responsible for the synthesis of estrogen, and estrogen is produced to a disproportionate extent in men with excessive amounts of fat, resulting in simultaneous glandular enlargement.
