1/4. Cutaneous bacillary angiomatosis.

    Bacillary angiomatosis is characterized by unique vascular lesions caused by infection with a small Gram staining bacillus of the genus Bartonella. It usually occurs in immunocompromised persons but can also occur in immunocompetent persons. We report a case of cutaneous bacillary angiomatosis in a 5-year-old immunocompetent child. He had infected lesions on the lips, after an injury, which was followed by lesions over the knees, buttocks, near the ankles and the elbows. diagnosis was proved on histology. The lesions cleared after administration of erythromycin for 3 months. It is well to be aware of this condition in the context of increasing prevalence of AIDS.

2/4. Clinical, histologic, microbiologic, and biochemical characterization of the causative agent of bacillary (epithelioid) angiomatosis: a rickettsial illness with features of bartonellosis.

    It has been suggested that bacillary (epithelioid) angiomatosis (BEA) is a manifestation of cat scratch disease (CSD). Because of clinical similarity between this condition and the verruga peruana phase of bartonellosis, we sought to further characterize this disease as well as its causative agent and to compare it to bartonellosis. We isolated a small flagellated pleomorphic bacillus from skin lesions of two patients with BEA. Organisms were stained successfully with Warthin-Starry silver stains, but immunohistochemistry failed to demonstrate binding with a polyclonal antibody directed against the cat scratch bacillus. Whole cell fatty-acid gas chromatography performed on both BEA organisms and bartonella bacilliformis demonstrated marked similarity between the two. Electron microscopy of BEA organisms in tissue and in suspension revealed features characteristic of a gram negative bacillus. Based on these findings, we propose that this unusual rickettsial infectious disease with vascular proliferation may represent an unusual variant of infection with a bartonella-like organism rather than a manifestation of cat scratch disease.

3/4. Case report 860: Bacillary angiomatosis of the calcaneum.

    Bacillary angiomatosis (BA) is newly reported infectious disease observed mainly in hiv-infected patients, caused by a small gram-negative bacillus of the Rochalimea genus. From a purely dermatological presentation similar to that of Kaposi's sarcoma, it may evolve into a systemic disease. Bone lesions seem fairly frequent. We report a case of an isolated osteolytic lesion due to the BA bacillus.

4/4. Bacillary angiomatosis and mycobacterium infection coexisting in a cutaneous lesion in a patient with AIDS.

    Bacillary angiomatosis is a recently recognized bacterial infectious disease. It mainly affects patients with acquired immunodeficiency syndrome. The presence of coexistent infections of more than one pathologic process in skin lesions in patients with AIDS has been demonstrated. We report a patient with AIDS in whom both bacillary angiomatosis and mycobacterium infection were documented within the same cutaneous lesion.
