title: Bacillary angiomatosis in an immunocompetent child: a case report and review of the literature.
abstract: Bacillary angiomatosis is an infectious disease caused by 2 gram-negative bacilli, Bartonella henselae and Bartonella quintana. This disease is characterized by vascular proliferations in the skin and/or visceral organs, and typically manifests in immunocompromised patients. However, we report a case of a 10-year-old immunocompetent female child with a questionable history of being scratched by a cat. Although initially diagnosed as a pyogenic granuloma, a diagnosis of bacillary angiomatosis was made based on histologic examination of the excised lesion demonstrating interstitial bacillary deposition on Warthin-Starry silver stain. The patient was successfully treated with 2 weeks of azithromycin after which all symptoms resolved.
