BA is a disorder of neovascular proliferation originally described involving skin and regional lymph nodes of HIV infected person (1,2). It has been demonstrated to involve a variety of internal organs, including liver, spleen, bone, brain, lung, bowel and uterine cervix (3-5) and to occur in other immunocompromised patients as well as immunocompetent hosts (6,7). Bartonella quintuna and B. henselae have been shown to be a cause of BA, both by direct culture (8).
