Bacillary angiomatosis
Appearing in numbers from one to hundreds, these lesions may take several forms:[citation needed] While cutaneous BA is the most common form, it can also affect several other parts of the body, such as the brain, bone, bone marrow, lymph nodes, gastrointestinal tract, respiratory tract, spleen, and liver.[citation needed] BA is characterised by the proliferation of blood vessels, resulting in them forming tumour-like masses in the skin and other organs.Usually, erythromycin will cause the skin lesions to gradually fade away in the next four weeks, resulting in complete recovery.If the infection is serious, then a bactericidal medication may be coupled with the antibiotics[citation needed] If a cat is carrying Bartonella henselae, then it may not exhibit any symptoms.[6] Following documentation of bacilli in Warthin-Starry stains and by electron microscopy in a series of cases by LeBoit and colleagues, the term bacillary angiomatosis was widely adopted.
