Fine structure of the spleen in autoimmune hemolytic anemia associated with systemic lupus erythematosus. 1978

N Matsumoto, and T Ishihara, and H Fujii, and H Nakamura, and F Uchino, and S Miwa

The fine structures of the red pulp of the spleen and the liver of a patient with autoimmune hemolytic anemia, neutropenia and thrombocytopenia associated with systemic lupus erythematosus are described. The red blood cells were phagocytized in toto by the splenic macrophages. These also contained neutrophils and platelets in various stages of degradation. Sinus endothelial cells revealed occasional erythrophagocytosis. The Kupffer cells in the liver occasionally contained red cells and platelets. These morphological findings and marked improvement of hematological abnormalities following splenectomy suggested that the spleen was the major site of destruction of blood cells. Undulating tubules associated with the endoplasmic reticulum were present in the sinus endothelial cells of the spleen.

D008180 Lupus Erythematosus, Systemic A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.
