The acquired immunodeficiency syndrome and other causes of immunosuppression have ushered in a variety of opportunistic infections. One of these is bacillary angiomatosis, a vasoproliferative lesion whose principal causative agent is Rochalimaea henselae. Bacillary angiomatosis, while preponderantly a cutaneous affliction, can be systemic, including involvement of the head and neck mucous membranes. Molecular technology and epidemiologic studies used to identify the bacterial agent of bacillary angiomatosis have also uncovered R henselae as the organism responsible for most cases of cat-scratch disease. Why the same organism promotes two different histopathologic lesions, as seen in bacillary angiomatosis and cat-scratch disease, is unknown.

UI	MeSH Term	Description	Entries
D002372	Cat-Scratch Disease	A self-limiting bacterial infection of the regional lymph nodes caused by AFIPIA felis, a gram-negative bacterium recently identified by the Centers for Disease Control and Prevention and by BARTONELLA HENSELAE. It usually arises one or more weeks following a feline scratch, with raised inflammatory nodules at the site of the scratch being the primary symptom.

D012514	Sarcoma, Kaposi	A multicentric, malignant neoplastic vascular proliferation characterized by the development of bluish-red cutaneous nodules, usually on the lower extremities, most often on the toes or feet, and slowly increasing in size and number and spreading to more proximal areas. The tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. Kaposi's sarcoma occurs spontaneously in Jewish and Italian males in Europe and the United States. An aggressive variant in young children is endemic in some areas of Africa. A third form occurs in about 0.04% of kidney transplant patients. There is also a high incidence in AIDS patients. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, pp2105-7) HHV-8 is the suspected cause.

D016917	Angiomatosis, Bacillary	A reactive vascular proliferation that is characterized by the multiple tumor-like lesions in skin, bone, brain, and other organs. Bacillary angiomatosis is caused by infection with gram-negative Bartonella bacilli (such as BARTONELLA HENSELAE), and is often seen in AIDS patients and other IMMUNOCOMPROMISED HOSTS.

D017789	Granuloma, Pyogenic	A disorder of the skin, the oral mucosa, and the gingiva, that usually presents as a solitary polypoid capillary hemangioma often resulting from trauma. It is manifested as an inflammatory response with similar characteristics to those of a granuloma.

D018416	Bartonella henselae	A species of gram-negative bacteria that is the etiologic agent of bacillary angiomatosis (ANGIOMATOSIS, BACILLARY). This organism can also be a cause of CAT-SCRATCH DISEASE in immunocompetent patients.	Rochalimaea henselae
