Abstract

Several reports have recently appeared in the literature describing "unique" non-neoplastic vascular lesions in patients with the acquired immunodeficiency syndrome (AIDS). These lesions may be mistaken clinically and histologically for Kaposi's sarcoma. The terms epithelioid angiomatosis, epithelioid or histiocytoid hemangioma, and pyogenic granuloma have all been used to describe a similar entity in which cat scratch disease bacillus (CSDB) was subsequently identified. Lesions closely resembling this entity occur in patients with bartonellosis. We report a case of a cutaneous vascular lesion on the hand of an AIDS patient in which cytomegalovirus (CMV) and organisms consistent with CSDB were both found. Simultaneous infections with CMV and CSDB have not been previously described. The presence of these organisms in and around endothelial cells may provide the common stimulus for the formation of these reactive vascular proliferations. © 1989.
