| Research Abstract |
Kaposi's sarcoma (KS) (Kaposi, 1872) is a soft tissue disease composed of angiogenetic tissue and spindle-shaped cells. The purpose of this study is to elucidate the latest findings of several points as follows: 1) Histogenesis: Studies employing immunohistochemistry and electron microscopy have suggested the origin of the tumor is pulripotential mesenchymal cells or endothelial cells of blood or lymphatic vessels. 2) Histopathology: In earlier stages, cutaneous edema and inflammatory cell infiltration are observed. Hemangiosarcoma-like patterns are observed frequently in the course of the disease. KS in advanced stages is composed of compact interlacing bundles of spindle cells. 3) Classifications: KS can be classified epidemiologically, clinically and histopathologically into three forms; African endemic form, classical form in Europe and North America and epidemic form of AIDS. 4) Epidemiology and geopathology: The relationship of KS to the natural environment, human ecology, socioeconomic conditions, genetic differences may be significant as a background for the occurence of KS. Our study revealed a geographical and ethnical coincidence of KS and Burkitt's lymphoma in Kenya, East Africa.
