[Mammary duct ectasia in children]

Authors describe two uncommon cases of infantile mammary duct ectasia (EDM). This disease, first reported in 1983, is characterized by dilatation of the subareolar duct system, and by phlogistic reaction and fibrosis. In the medical literature only 8 cases have been reported, but probably its frequency is undervalued due to the scarce general knowledge of this pathology. The differential diagnosis is reviewed.
