[Erosive adenomatosis of the nipple. Report of 2 cases].

Superficial papillary adenomatosis of the nipple is a benign tumor of the ductal epithelium that clinically resembles Paget's disease. Unilateral serous, bloody, or serosanguinous discharge with crusting is most commonly present. Symptoms include tenderness or pruritus. Histologically, the tumor is characterized by proliferating ductal structures lined by a double layer of columnar epithelium. The lesions are focally eroded. Keratin cysts and apical intraluminal projections are commonly found. The original description was reported in 1954 in the english language literature. Just a few cases have been reported in the french literature. These cases are reviewed and two classic examples are reported; their therapeutic options are discussed.
