Clinical Features of Intraductal Papilloma
1. This condition can occur in women of any adult age, but is most common in women aged 40–50, possibly related to ovarian dysfunction.
2. The most prominent feature is occasional bloody nipple discharge, though a lump is often not palpable. Slight pressure on the nipple reveals bloody fluid, enabling diagnosis.
3. In 75% of cases, lesions occur in the enlarged portion of the major duct near the nipple. Tumors are usually small, some with a stalk and villous projections, and numerous thin-walled blood vessels, leading to frequent fresh blood discharge from the nipple.
4. The affected breast is generally painless. If the tumor is large and obstructs the duct, local distension and pain may occur, which disappear after blood accumulation is released. This phenomenon may recur.
5. Ductography shows multiple papillary defects within dilated ducts.<Breast>
