[Management of nipple-areolar complex anomalies]

Nipple-areolar complex anomalies may be secondary to many etiologies from simple anatomic variations to malignant processes as Paget disease or invasive breast cancer, passing through benign locally aggressive processes as erosive adenomatosis of the nipple. Differential diagnosis is not always simple. If clinical exam and standard radiological checkup can't confirm the benignity of the lesion, a biopsy specimen will be obtained to allow an anatomopathological examination. A precise diagnosis can then be made leading to optimal management. This paper describes how to explore nipple-areolar complex anomalies through an uncommon clinical case associating independently an invasive retro-areolar cancer and a dermatological disease of the areola mimicking a Paget disease.
