Malignant angioendotheliomatosis is a rare, systemic, usually fatal disease characterized by a massive proliferation of large, bizarre-looking mononuclear cells within small and medium-sized blood vessels. The histogenesis of the neoplastic cells has been the subject of long-standing controversy since the disease's initial description. Early investigators concluded that the entity represented a neoplasm of endothelial cells, but recently others have suggested that it is of lymphoid origin. We studied a case of malignant angioen-dotheliomatosis by Southern blot hybridization analysis which showed clonal rearrangements of the immunoglobulin heavy-chain gene strongly suggesting a B-lymphocyte origin. Our results provide additional evidence that malignant angioendotheliomatosis is an intravascular malignant lymphomatosis.
