Bacillary angiomatosis (BA) is an angioproliferative disease caused by species. It manifests as nodules or papules in immunocompromised patients. Oral lesions are very rare, unlike cutaneous lesions, and histopathology plays a vital role in distinguishing these lesions from other similar ones. Treatment mainly comprises macrolides erythromycin, clarithromycin, or doxycycline.

A 34-year-old male patient presented with a clinical picture of multilocular subcutaneous skin nodules in addition to marked lymphadenopathy and general physical deterioration. A comprehensive diagnostic workup including serology, skin biopsy and imaging studies led to the initial diagnosis of human immunodeficiency virus (HIV) infection in AIDS stage with rare multilocular subcutaneous bacillary angiomatosis (BA) caused by Bartonella henselae. BA describes a process of neovascularisation of the skin or of internal organs (particularly the liver and spleen) and was first described in HIV-positive patients by Stoler et al.

a Gram-negative facultative intracellular bacterium, is the etiological agent of cat-scratch disease and also causes bacillary angiomatosis in immunocompromised individuals. Although the ability to promote vascular endothelial cell proliferation differs among species, variations among strains within remain unclear. angiogenic factor A (BafA) and adhesin A (BadA) have been identified as autotransporters of that are involved in endothelial cell proliferation.
