imaging techniques. Bilateral diffuse breast involvement by multiple small nodules has been described twice in disseminated RDD, involving the breast parenchyma in addition to other nodal, visceral or non-visceral sites, similar to the findings in our patient.RDD needs to be considered in the differential diagnosis of single or multiple mass lesions in the breast, especially in patients with a history of RDD at other sites. After histologic confirmation of this benign condition, RDD of the breast does not require treatment. It can be self-limiting and has mostly an indolent clinical course; however, disseminated RDD with multi-system involvement portends a poorer prognosis.
