Bacillary Angiomatosis or Kaposi's Sarcoma?
The New England Journal of Medicine, 1997Co-Authors: Jordan W. Tappero, Jane E KoehlerAbstract:Figure 1. Bacillary Angiomatosis and Kaposi's sarcoma can be especially difficult to differentiate clinically. In each pair of figures, one shows a bacillary Angiomatosis lesion (Panels A and B) and one shows a clinically indistinguishable Kaposi's sarcoma lesion (Panels C and D). There are many causes of moist, erosive cutaneous vascular lesions in immunocompromised patients. A tissue biopsy is required for diagnosis. Other bacterial and fungal infections, as well as pyogenic granuloma, may also have similar clinical appearances. On routine staining with hematoxylin and eosin, bacillary Angiomatosis lesions show acute neutrophilic inflammation and capillary proliferation. Kaposi's sarcoma lesions show slit-like . . .

molecular epidemiology of bartonella infections in patients with bacillary Angiomatosis peliosis
The New England Journal of Medicine, 1997Co-Authors: Jane E Koehler, Philip E. Leboit, Margot J. Whitfeld, Melissa A Sanchez, Claudia S Garrido, Frederick M Chen, Timothy G Berger, Maria C Rodriguezbarradas, Jordan W. TapperoAbstract:Background Bacillary Angiomatosis and bacillary peliosis are vascular proliferative manifestations of infection with species of the genus bartonella that occur predominantly in patients infected with the human immunodeficiency virus. Two species, Bartonella henselae and B. quintana, have been associated with bacillary Angiomatosis, but culture and speciation are difficult, and there has been little systematic evaluation of the species-specific disease characteristics. We studied 49 patients seen over eight years who were infected with bartonella species identified by molecular techniques and who had clinical lesions consistent with bacillary Angiomatosis–peliosis. Methods In this case–control study, a standardized questionnaire about exposures was administered to patients with bacillary Angiomatosis–peliosis and to 96 matched controls. The infecting bartonella species were determined by molecular techniques. Results Of the 49 patients with bacillary Angiomatosis–peliosis, 26 (53 percent) were infected wit...

bacillary Angiomatosis associated with myositis in a patient infected with human immunodeficiency virus
Clinical Infectious Diseases, 1997Co-Authors: Margot J. Whitfeld, Jane E Koehler, Sassan Kaveh, Paul S Mead, Timothy G BergerAbstract:A man with AIDS presented with a deep soft-tissue mass involving the right thigh. Biopsy of a skin lesion on the back and culture of a specimen from this lesion showed bacillary Angiomatosis due to Bartonella (formerly Rochalimaea) quintana. Magnetic resonance imaging revealed a large heterogeneous mass involving the vastus medialis and intermedius muscles. Therapy with erythromycin caused rapid resolution of both the cutaneous lesion and the muscle lesion. Bartonella infection is proposed as an additional cause of bacterial myositis and expands the spectrum of presentation of bacillary Angiomatosis.

Bacillary Angiomatosis of the cervix and vulva in a patient with AIDS.
Obstetrics & Gynecology, 1996Co-Authors: Steven R. Long, Jane E Koehler, Margot J. Whitfeld, Carol A. Eades, Abner P. Korn, Charles ZaloudekAbstract:Background Bacillary Angiomatosis is a clinicopathologic entity that most often is identified in the skin of patients with AIDS. This report presents an example of bacillary Angiomatosis of the female genital tract. Case Bacillary Angiomatosis presented as red-purple nodules of the vulva and cervix in a 32-year-old woman with AIDS. Histologic examination revealed the lobular epithelioid vascular proliferation and hazy clumps of bacteria that characterize bacillary Angiomatosis. The diagnosis was confirmed on Warthin-Starry-stained tissue and by blood cultures, which were positive for Bartonella ( Rochalimaea ) henselae . Conclusion Accurate diagnosis of this infection is important because 1) bacillary Angiomatosis is commonly mistaken for Kaposi sarcoma, 2) it is effectively treated with inexpensive antibiotics, and 3) undiagnosed and/or untreated bacillary Angiomatosis may lead to overwhelming disseminated infection and death.

intra abdominal mass associated with gastrointestinal hemorrhage a new manifestation of bacillary Angiomatosis
Gastroenterology, 1995Co-Authors: Jane E Koehler, Laurie CederbergAbstract:Bacillary Angiomatosis is a recently described vascular proliferative lesion that occurs most commonly in individuals infected with human immunodeficiency virus. Cutaneous lesions are the most frequently described manifestations of bacillary Angiomatosis. However, as culture techniques and disease recognition have improved, additional manifestations have been identified in human immunodeficiency virus-infected individuals, including bacillary peliosis hepatis and isolated bacteremia. Two species of the genus Bartonella (formerly Rochalimaea), Bartonella henselae or Bartonella quintana, have been cultured from the cutaneous lesions of bacillary Angiomatosis. A new manifestation of Bartonella infection is reported: an intra-abdominal mass presenting with massive gastrointestinal hemorrhage in a patient with human immunodeficiency virus infection. B. quintana was cultured from a percutaneous needle-biopsy specimen obtained from the highly vascularized intra-abdominal mass. The bacillary Angiomatosis lesion resolved after 3 months of tetracycline treatment. Recognition of Bartonella infection is extremely important because it is readily treatable with antibiotic therapy.

isolation of rochalimaea species from cutaneous and osseous lesions of bacillary Angiomatosis
The New England Journal of Medicine, 1992Co-Authors: Jane E Koehler, Philip E. Leboit, Timothy G Berger, Frederick D Quinn, Jordan W. TapperoAbstract:Abstract Background. Bacillary Angiomatosis is characterized by vascular lesions, which occur usually in patients infected with the human immunodeficiency virus (HIV). A newly described gram-negative organism, Rochalimaea henselae, has been associated with cutaneous bacillary Angiomatosis, but no organism has been isolated and cultivated directly from cutaneous tissue. Methods. We used two methods to isolate the infecting bacterium from four HIV-infected patients with cutaneous lesions suggestive of bacillary Angiomatosis: cultivation with eukaryotic tissue-culture monolayers and direct plating of homogenized tissue onto agar. The patients' blood was cultured with the lysis—centrifugation method. Isolates recovered from skin and blood were identified by sequencing all or part of the 16S ribosomal RNA gene amplified with the polymerase chain reaction. Results. R. quintana, historically known as the agent of trench fever, was isolated from cutaneous lesions in three patients, after tissue homogenates were c...
