Benign Fibrous Histiocytoma in Hodgkin's Disease

Abstract

A case of benign fibrous histiocytoma in a patient with previous Hodgkin's disease is reported. Benign fibrous histiocytoma consists of a proliferation of benign histiocytes in addition to inflammatory cells and occasional Reed-Sternberg-like cells. Hodgkin's disease is considered a malignant disorder of the monocyte-histiocyte cell line but also includes benign inflammatory cells as part of its histological picture. The possibility that these two entities are biologically related is considered. The pathogenic relationship between both entities is discussed in the context of the immune dysregulation associated with Hodgkin's disease.
