Polypoid endobronchial lesions occurred in a patient with acquired immunodeficiency syndrome (AIDS) with recent fever, skin lesions, lymphadenopathy, lung infiltrates, and pleural effusions. His condition improved with antimicrobials and vincristine. After therapy ceased, skin lesions recurred and gastroesophageal mucosal lesions developed. Bacillary angiomatosis was identified during retrospective analysis of skin and endobronchial biopsy specimens.

Bacillary angiomatosis, a cutaneous lesion newly recognized to affect patients with AIDS, may resemble Kaposi sarcoma. It is presumed to be an infectious process caused by the gram-negative bacilli associated with cat-scratch fever. We present a case of bacillary angiomatosis in a pregnant AIDS patient.

Bacillary angiomatosis is a newly recognized multisystem bacterial infectious disease seen in the setting of human immunodeficiency virus (HIV) infection. The disease is marked by cutaneous vascular lesions that contain a bacterium similar to the cat scratch disease bacillus. Antibiotic therapy leads to the resolution of both cutaneous and systemic manifestations. Of 17 HIV-infected patients with cutaneous lesions of bacillary angiomatosis, six (35%) had symptomatic osteolytic bone lesions that improved following antibiotic therapy. The authors describe the appearance of the bone lesions on radiographs, computed tomographic (CT) scans, magnetic resonance (MR) images, and radionuclide studies. Osteolytic lesions are a relatively common feature of bacillary angiomatosis in patients with HIV infection. The presence of bone lesions aids in differentiation of bacillary angiomatosis from acquired immunodeficiency syndrome-related Kaposi sarcoma, which has similar cutaneous abnormalities but no associated bone lesions.

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.

In recent years, especially with the advent of acquired immunodeficiency syndrome, new skin disorders associated with systemic disease have been described in the literature. Eosinophilic folliculitis and pruritic papules of human immunodeficiency virus (HIV) infection are clinically similar lesions that respond to phototherapy. Bacillary angiomatosis, another HIV-related skin disease that is caused by a pleomorphic gram-negative organism, resembles Kaposi's sarcoma clinically but is curable if treated early with antibiotics. Toxic strep syndrome, a scarlatiniform, desquamative eruption associated with hypotension, fever and multiorgan system dysfunction, is caused by group A streptococcal soft tissue infection. Paraneoplastic pemphigus, a recently characterized autoimmune vesicular eruption, produces painful mucocutaneous ulcerations in patients with an occult neoplasm, such as chronic lymphocytic leukemia or malignant lymphoma.

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.

A 52-year old male homosexual patient with acquired immunodeficiency syndrome (AIDS) presented in our clinic with multiple nodular papules (more than 100) spread over the whole body which had developed within 3 months. Bacillary angiomatosis was suspected, which is a bacterial infectious disease recognized recently mainly in patients with AIDS. Histological and immunohistochemical examinations of extirpated skin lesions were in agreement with the diagnosis, and the detection of rod-shaped bacteria in the lesions by Warthin-Starry silver stain confirmed it. The patient was treated with 2 x 100 mg doxycycline per day. The fever disappeared, and the cutaneous lesions showed a slight tendency to improve. However, after 5 days of therapy the patient showed increasing weakness, with muscle and bone pain. The patient died 10 days after the doxycycline therapy had been started. The cutaneous lesions in bacillary angiomatosis may resemble Kaposi's sarcoma and may therefore be misdiagnosed. The disease may be fatal, but timely antibiotic treatment is usually effective; therefore, the diagnosis of bacillary angiomatosis is important. Although many cases have been reported from the United States, only one case is known from Europe. Our finding of bacillary angiomatosis in a German AIDS patient supports the concept of a worldwide distribution of this bacterial agent.

Bacillary angiomatosis is a newly characterized infectious disease occurring mainly in patients with AIDS. Most patients have cutaneous angiomatosis lesions resembling Kaposi's sarcoma or pyogenic granuloma. Although the disease may be life-threatening if not treated, it is curable with appropriate antibiotic therapy. A patient had a fever, nightsweats, abdominal pain, pleural effusions, and asymmetric peripheral lymphadenopathy. Computed tomography of the chest and abdomen revealed a unique pattern of enhancement of lymph nodes that, to this research team's knowledge, has not been reported previously with this condition. Appropriate antibiotic therapy resulted in a complete resolution of the disease. Included is a discussion of the clinical presentation, etiology, histology, and treatment of bacillary angiomatosis.

Bacillary angiomatosis is known to be caused by a rickettsial organism; Rochalimaea henselae. This causative agent has been compared with different microorganisms and clinical conditions that appear in similar settings buy have been clearly differentiated from them; e.i. Cat-scratch disease (Afipia felis), Bartonella bacilliformis, other Rochalimaea sp., Kaposi's sarcoma, Lobular capillary hemangioma, Angiosarcoma, and Epithelioid hemangioma. Clinically the bacillary angiomatosis (BA) skin lesions vary from a single lesion to thousands. The cutaneous lesion appears as a bright-red round papule, subcutaneous nodule, or as a cellulitic plaque. When the lesion is biopsied it tends to blanch-out, bleed, and cause pain. The patient might present with signs and symptoms of chills, headaches, fever, malaise, and anorexia with or without weight loss. The extracutaneous lesions found in BA tend to be from multiple organs affecting from the oral lesions to anal mucosal lesions to widespread visceral lesions. The sites of preference for BA lesion manifestation tend to be the liver, spleen, lymph nodes, and bone. To diagnose bacillary angiomatosis the physician should prepare a differential diagnosis based primarily on its histopathological and clinical characteristics. To confirm the results from the stain, electron microscopy can identify the bacillus and pin-point the diagnosis of bacillary angiomatosis. The lesions presented by BA respond well to therapy with erythromycin 500 mg four times daily for a duration of 2 weeks to 2 months. In case of intolerance to erythromycin the second line of drug that successfully treats the BA bacillus is doxycyline. If relapses of the BA lesion recur, then a prolonged antibiotic therapy is necessary and in AIDS patients the duration may be extended as life-long suppressive therapy.
