Malignant histiocytosis: a clinico-pathological study of 12 cases. 1978

I A Lampert, and D Catovsky, and N Bergier

The clinico-pathological features of 12 cases of malignant histiocytosis (histiocytic medullary reticulosis), aged 12-60 years, were studied. Special emphasis was put on the analysis of the haematological, cytological and histopathological findings of the disease. Bone marrow aspirates and biopsies from involved tissues (liver, lymph node, spleen and skin) were found best suited for establishing the diagnosis. Cytochemical and ultrastructural data support the concept that the neoplastic cells belong to the mononuclear-phagocyte system. Three untreated patients died in less than 6 months. Median survival of the nine treated patients was 1 year. Seven patients were treated with the combination chemotherapy CHOP and four achieved a complete remission. Three of them are alive and continue in unmaintained remission for more than 1 year, surviving so far for 18+ to 31+ months. Two cases showed evidence of CNS involvement, one during life and the other as a post-mortem finding. The differential diagnosis from other related or unrelated disorders and the possible aetiological factors responsible for the disease are discussed in detail.

D008206	Lymphatic Diseases	Diseases of LYMPH; LYMPH NODES; or LYMPHATIC VESSELS.	Lymphatism,Status Lymphaticus,Disease, Lymphatic,Diseases, Lymphatic,Lymphatic Disease
D008297	Male		Males
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D012075	Remission, Spontaneous	A spontaneous diminution or abatement of a disease over time, without formal treatment.	Spontaneous Healing,Spontaneous Regression,Spontaneous Remission,Healing, Spontaneous,Regression, Spontaneous,Spontaneous Healings,Spontaneous Regressions
D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
