Bacillary angiomatosis (BA) is an angioproliferative disease of immunocompromised
patients that usually presents as vascular tumors in the skin and subcutaneous
tissues. It is caused by chronic infections with either Bartonella
henselae or B. quintana. Oral cavity BA is exceedingly
rare and even rarer without simultaneous cutaneous disease. We report herein the case
of a 51-year-old HIV-infected man who presented severe odynophagia and an eroded
lesion on the hard palate that progressed to an oronasal fistula. No cutaneous
lesions were recorded. Doxycycline led to complete resolution. To the best of our
knowledge, only six previous cases of oral BA without tegumentary disease have been
previously reported and none of them progressed to fistula.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
