Thymic cysts in mediastinal Hodgkin disease.

Abstract

Three cases of proved thymic cysts associated with mediastinal Hodgkin disease are presented. Two illustrate regression of lymphoma with chemotherapy but persistence of thymic cysts. The 3rd case demonstrates a thymic cyst in untreated Hodgkin disease. Such cysts are probably neither coincidental with nor a consequence of therapy but are probably related to initial thymic involvement by Hodgkin disease.
