Definition of Angiomatosis, bacillary Angiomatosis, bacillary: A
bacterial infection due to a cat scratch most often seen today
in people with HIV. The disease characteristically presents with
swollen lymph nodes (lymphadenitis), sore throat, fatigue, and
fever, chills, sweats, vomiting, loss of appetite, and weight
loss. There is usually a little bump (a papule) which may be
pus-filled (a pustule) at the site of the scratch. Then more
nodules appear on and under the skin. As the number of nodules
increases, patients get sicker. In normal people the disease is
self-limited and usually goes away by itself in a few weeks. It
can also be treated with antibiotics. In persons with HIV/AIDS
the disease can cause severe inflammation of the brain, bone
marrow, lymph nodes, lungs, spleen and liver. The disease can be
fatal in persons with HIV. It can be easily treated with
antibiotics such as erythromycin and doxycycline. Treatment is
given until the skin lesions resolve, usually in 3 to 4 weeks.
