Human breast gross cystic disease is a common benign breast disease which occurs most frequently in the age range of 40-50 years, then becomes very infrequent after menopause. It is characterized by production of a unique fluid secretion which accumulates in the breast cysts composed of several glycoproteins, including a unique 15kD monomer protein, GCDFP-15. The protein is present in normal apocrine epithelium, metaplastic apocrine epithelium of the breast, and breast carcinomas with apocrine features. The protein is regarded as a specific functional marker of apocrine cells. It is expressed during fetal development and may represent a common marker of embryologically linked glandular structures. The gene coding for GCDFP-15 is localized in the long arm of chromosome 7.
