[Microglandular adenosis of the breast in a patient with a history of mediastinal radiotherapy]. / Adenosis microglandular mamaria en paciente con antecedente de radioterapia mediastínica.

The risk of secondary tumors in patients who have received mediastinal radiation therapy is well-known. Microglandular adenosis of the breast is a rare lesion that is considered benign, although its possible role as a precursor of invasive breast carcinoma has been considered. We present a case of microglandular adenosis in a patient who received mediastinal radiation therapy in childhood for Hodgkin's lymphoma. To our knowledge, this is the first reported case of microglandular adenosis in a patient with mediastinal radiotherapy which may shed light on its pathogenesis.
