Conjunctival regressing Kaposi sarcoma.

KAPosI multiple idiopathic haemorrhagic sarcoma is a peculiar condition which cannot be accurately classified (Reese, 1963). It was regarded by Kaposi (1872) as a cutaneous sarcoma affecting the blood vessels; by Ewing (1922) as an infectious granuloma; by Pautrier and Diss (1928) as originating from nerve tissue; and by D6rffel (1932) as arising from the reticulo-endothelial system, the lesion being an angio-reticulo-endothelioma (Choisser and Ramsey, 1940; Sutton, 1956). Allen (1954) quoted fifteen examples of concomitant association of Kaposi sarcoma and malignant lymphoma and believed this to be more than an accidental coincidence. It is uncertain whether Kaposi sarcoma is a true neoplasm, but in some cases it certainly behaves like one (Cappell, 1958). The pathological nature of the lesion is also uncertain, although its general structure is sarcomatous (Duke-Elder, 1952). Soderman (1959) wrote:
