Abstract

Abstract: Background: The clinical manifestation of bacillary angiomatosis (BA) can be limited to one organ, most commonly the skin, but systemic courses can also occur. We report a human immunodeficiency virus (HIV)-positive patient with a systemic manifestation of BA caused by Bartonella quintana, diagnosed in Vienna, Austria. The pathogen was detected in multiple organs including a facial tumor which is an unusual finding for BA. Furthermore, infections with B quintana are rare in our area and no other autochthonous cases have been reported. Methods and results: The clinical manifestation included multiple papules and nodules on the entire body, several organic abscesses, and a facial tumor influencing the patient's view. The main laboratory finding indicated HIV infection combined with severe immunosuppression with 47 CD4 + cells/μL. Contrast-enhanced computed tomography of the chest and the abdomen showed multiple and abscesses. Histological examination of the facial tumor confirmed inflammatory process. Bartonella quintana was detected by PCR in blood and in the facial tumor as well as by culture in the skin tissue. Antibiotic treatment with doxycycline and antiretroviral therapy resulted in clinical improvement. Conclusion: Our case shows that rare opportunistic, vector-borne infections, usually associated with poverty, can lead to diagnosis of HIV even in well-developed countries. Furthermore, we provide details on clinical manifestation and diagnostic work-up which might expand the knowledge on disseminated infections with B quintana . As far, tumorous deformations have rarely been reported as consequence of BA. In our patient the pathogen was detected in the facial tumor using PCR techniques.
