ABSTRACT

Bacillary angiomatosis described in 1983 as cutaneous and subcutaneus vascular lesions, is transmitted by several vectors, cause several clinical syndromes: cat-scratch disease, Carrion’s disease and peruvian wart, endocarditis and neuroretinitis, bacillary angiomatosis and hepatic peliosis by B. henselae and B. quintana. In bacillary angiomatosis lesions are found on the skin, form friable nodes, subcutaneous lesions have the appearance of cystic nodules or epidermal cysts. The diagnosis is made by biopsy, lobular proliferation of capillaries and small vessels with large endothelial cells surrounded by inflammatory infiltrate and isolated areas of necrosis are observed. With hematoxylin and eosin bacteria clusters near blood, bacillary angiomatosis indicative vessels are observed. It can be treated with antibiotics, if the diagnosis is delayed there is high morbidity and mortality. The first-line antibiotics are erythromycin and doxicilcina, between 8 to 12 weeks. Bacillary angiomatosis is mainly observed in patients with AIDS, is included in category B. B. quintana infection is found in patients with low socioeconomic status, vagabonds, with chronic alcoholism and body lice. B. henselae has a feline reservoir established and is associated with cat bites or scratches and bites of these fleas.
