Transformation of Hodgkin's disease into malignant fibrous histiocytoma

The continuity that exists between Hodgkin's disease and the fibrohistiocytoses has only recently been recognized. Four cases are presented that illustrate this phenomenon. The fibrohistiocytic component of the Hodgkin's lesion may lag behind the lymphoreticular component, may be present in equal proportion, or may assume a dominant role, with the emergence of a frank fibrohistiocytosis or fibrous histiocytoma being evidenced as the lymphoreticular component recedes.
