[Kaposi's sarcoma--ultrastructural study of 7 cases].
The ultrastructure of 7 cases of Kaposi's sarcoma observed in Xinjiang is reported. Its histo-structure and cell type varied. The neoplastic blood vessels, pericytes, fibroblasts, epithelioid cells with their basement membranes and cell junctions (tight junction and desmosome-like junction), spindle cells with multi-microvilli, phagocytes and mesenchymal cells without any cellular characteristics were found. The nature of these cells and the relation between them are discussed. The authors support the opinion that Kaposi's sarcoma is derived from primitive vasoforming mesenchyme.
