[Milk-duct papillomas of the breast: diagnosis, clinical course, morphology and associated pathology].

From 1978 through 1982, 52 cases of benign intraductal papilloma were observed in the Histopathology Laboratory of the University Women's Hospital, Zürich. The neoplasms were solitary in 20 cases and multiple in 32. Symptomatology, diagnosis and therapy of these tumors are presented and discussed. The indication for biopsy or further histological examination was a pathological palpatory finding (54%), discharge from the nipple (36.5%), or an incidental mammographic finding (9.5%). Five (15.5%) of the 32 patients with multiple intraductal papilloma, but none of those with solitary papilloma, had an associated carcinoma in the same breast.
