title: Bacillary angiomatosis: a new entity in acquired immunodeficiency syndrome.
abstract: Since the recognition of the acquired immunodeficiency syndrome (AIDS) in 1981, previously rare infections and neoplasms have become increasingly common. Bacillary angiomatosis, undescribed in the medical literature prior to 1983, is now second in frequency only to Kaposi's sarcoma with respect to the cutaneous manifestations associated with human immunodeficiency virus (HIV) infection. Caused by Rochalimaea henselae, bacillary angiomatosis is easily treated, when diagnosed early, with erythromycin. We present two cases of bacillary angiomatosis that presented to Toronto General Hospital and review this new and clinically interesting entity. The incidence of bacillary angiomatosis will undoubtedly increase as the HIV epidemic accelerates. Since bacillary angiomatosis commonly affects the head and neck region, it is important for the otolaryngologist to become increasingly proficient in its diagnosis and treatment. The current AIDS crisis demands that the otolaryngologist become aware not only of bacillary angiomatosis, but also of the other cutaneous head and neck manifestations of HIV infection.
