Verruga peruana: an infectious endemic angiomatosis.
Microbial-related dysplastic and neoplastic angiomatous proliferative processes are seen with increased frequency, particularly in the acquired immunodeficiency syndrome (AIDS). The microbial-encoded or -induced mediators of angiopathogenesis in AIDS-associated Kaposi's sarcoma and bacillary angiomatosis are actively being sought. The present review addresses the historical, epidemiologic, clinical, etio- and histopathogenic aspects of the verruga peruana (VP). VP is a disease thus far endemic to high Andean valleys and characterized by dermal angioblastic proliferation in association with reactivation of latent Bartonella bacilliformis organisms. VP closely resembles AIDS-associated angiopathogenic manifestations at the clinical, histopathologic, and etiologic levels and therefore has been proposed as a model for the study of angiogenesis and endothelial cell dysplasia and neoplasia. Moreover, the recent epidemic outbreaks in endemic areas, the increased frequency of international travel to the region, the variable incubation period, and the possibility of not recognizing VP due to its rarity further underscore the relevance of studying this rare disorder and of including it in the differential diagnosis of angiomatous-proliferative disorders.
