Bacillary angiomatosis is a newly recognized pseudoneoplastic vascular disease seen in the setting of human immunodeficiency virus (HIV) infection. The disease is characterized by a cutaneous infection with reddish papules or nodules that are similar to pyogenic granulomas or Kaposi's sarcoma in clinical appearance. It is caused by the mildly gram-negative bacillus Rochalimaea henselae, which can be identified in tissue sections by means of Warthin-Starry stain. The historical, clinical, histopathological, and microbiological aspects and the differential diagnosis and therapy of bacillary angiomatosis are reviewed. It is important to be aware of these characteristics, because these lesions can easily be treated with antibiotic therapy.

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.
