title: Papular mucinosis of the breast after radiation therapy.
abstract: Localized papular mucinosis is a type of mucinosis induced by several different causes. However, to the best of our knowledge, prior radiation therapy has not been reported to be related to papular mucinosis. We present a case of a 47-year-old woman who had undergone an operation for a breast carcinoma 2 years earlier and received local radiotherapy in the affected breast. Currently, she presents multiple erythematous papules that are caused by abundant dermal mucin deposits. We discuss some potential differential diagnoses.
