[Papillomatous lactic-duct adenoma (pseudoPaget's disease of the mamilla)].

Papillomatosis and adenomatosis of the nipple ducts can be interpreted clinically as Paget's disease. Three patients with subareolar papillomatosis and adenomatosis are described. The name papillary adenoma of the nipple ducts (pseudo-Paget's disease has been proposed. The differentiation between the papillary adenoma of the nipple ducts and the genuine Paget's disease needs histological examination. The differential diagnosis is very important, because local excision of the diseased ducts represents the treatment of choice of the papillary adenoma of the nipple ducts. Radical mastectomy is always necessary in genuine Paget's disease since the adjacent lactiferous ducts are involved by the carcinoma.
