Answer

Bacillary angiomatosis caused by Bartonella henselae and Bartonella quintana is rare in children but has been reported. [23] Bacillary angiomatosis is considered by some to be an AIDS-defining opportunistic infection, typically seen with a CD4+ count less than 200 cells/μL. Clinically and histologically, the lesions often resemble pyogenic granulomas and Kaposi sarcoma. They often begin as pinpoint papules, which enlarge to become red nodules and usually involve the face or the upper torso. In addition to the cutaneous findings, these patients may have lymphadenopathy, abdominal symptoms, anemia, and an elevated alkaline phosphatase level.
