Nipple adenoma of breast: a masquerader of malignancy

ABSTRACT Nipple adenoma is a benign condition simulating malignancy such as breast carcinoma and/or Paget's disease clinically. In this study 19 cases diagnosed as nipple adenoma over a period of 14 years are described. The diagnosis was confirmed by histology alone. All patients were females with age ranging from 23 to 63 years. Most of the cases presented clinically with in duration and ulceration accompanied by pain and itching. The diagnosis was clinically suspected in only 3 cases. This highlights the importance of histological diagnosis in all suspicious breast lesions. In one case, the clinical and histological diagnosis was incorrect leading to mastectomy. Complete local excision with clear margins is curative.
