True gynecomastia is defined by the presence of glandular breast tissue.

• A. Accumulation of adipose tissue
• B. Presence of glandular breast tissue
• C. Fibrous scar tissue in the chest
• D. Absence of glandular tissue

Answer: (B)

True gynecomastia is defined by the presence of glandular breast tissue. This reflects proliferation of the glandular component under the nipple-areola complex, not just an increase in fat. In contrast, chest enlargement from adipose tissue alone is called pseudogynecomastia. Scar tissue or absence of glandular tissue would not meet the definition of true gynecomastia.
