title: Spontaneous regression of sarcoma.
abstract: Three pathologic processes generally regarded as nonneoplastic conditions are presented and discussed as examples of poorly controlled proliferations of lymphoid tissue. A study of these three disorders (infectious mononucleosis, hyperthyroidism, and Dilantin-induced lymphadenopathy) provides clues to an understanding of the pathogenesis and occasional spontaneous regression of the malignant lymphomas.
