[Paget's disease of the nipple]

Abstract

Fifty-five female patients with Paget's disease of the nipple treated in our Hospital from 1958 to 1987 are reported. It comprised 1.1% of all the breast carcinomas. The lesions was on the left side in 27 and on the right side in 28. The average age was 48 years. The primary lesion was in breast ducts and then invaded the nipple, areola superficially and deeper breast tissue. Dermal manifestation of Paget's disease is easily confused with chronic dermopathy. In this series, four patients (7.2%) did not have the typical symptoms so pathologic or cytologic examination was relied upon for correct diagnosis. Thirty-one patients were treated by radical mastectomy giving a 3-year disease-free rate of 70.9%. It seems that radical mastectomy is more superior to the other surgical procedures. The 3-year recurrent rate was 38% for patients with Paget's disease of the nipple coexisting with breast carcinoma, but no recurrence was found in patients with simple Paget's disease of the nipple. The 3-year survival rate was 46.4% in patients with axillary lymph node metastasis, 85.2% in patients without, 54.3% in patients with palpable masses in the breast and 85.0% in patients without. Paget's disease of the nipple coexisting with breast carcinoma, axillary lymph node metastasis, palpable breast masses has poor prognosis.
