Extractions: POSTER 3A MAN WITH RED NODULES ON THE FACE AND EXTREMITIES Brett Dock MD, Meena Moossavi MD, George Murakawa MD PhD A 37 year old HIV positive African-American man was admitted with a 3 month history of red lesions on his face and extremities. The patient complained of pain and pus draining from the lesion on his right knee. He denied contact with cats, was not homeless, and had no history of body lice. The lesions sometimes bled, but were otherwise asymptomatic. The patient was stable and afebrile. He had discontinued all medications 2 months prior to admission. He had no known drug allergies and no other medical history. Examination revealed a 5 cm x 6 cm soft, purulent, tender, necrotic tumor on the right knee. There was a 1.2 cm umbilicated erythematous tumor on the left elbow and 4 cm violaceous tumors on the left knee and left ankle. The patient had right inguinal lymphadenopathy. LABORATORY Blood cultures: negative CD T-helper cell count: 20 Biopsies of the temple and elbow revealed a proliferation of blood vessels lined by epithelioid endothelial cells. There was a perivascular neutrophilic inflammatory infiltrate and amorphous eosinophilic material. Warthin-Starry stain revealed positively staining bacilli. These findings were consistent with bacillary angiomatosis. The patient was treated with azithromycin 250 mg qd. Antiretroviral therapy and Bactrim prophylaxis were started. The lesions rapidly improved within one week after starting therapy.

Sie kommt, wenngleich selten, auch hierzulande vor und ist bei allen unklaren Hauteffloreszenzen eine wichtige Differentialdiagnose. Die pseudoneoplastischen, vaskulären Haut-Proliferationen werden klinisch (und histologisch!) sehr oft mit Kaposi-Sarkomen oder auch Hämangiomen verwechselt. Verursacht wird die bazilläre Angiomatose durch die beiden Rickettsien-Spezies Bartonella henselae und Bartonella quintana (bis Anfang der 90er Jahre noch "Rochalimaea"). Katzen sind der Hauptwirt für Bartonella henselae, Katzenflöhe der Vektor. Bei Bartonella quintana erkranken häufig Patienten aus sozial schwachen Verhältnissen, insbesondere Obdachlose.

B. henselae are intraerythrocytic bacteria, therefore cell lysis, using a lysis centrifugation technique, greatly facilitates bacterial isolation from blood. Bacteria in the genus Bartonella are very fastidious, requiring up to 60 days to identify bacterial colonies. Seroconversion, using IFA or ELISA, can be used to confirm a diagnosis in people with acute disease. Because of disparate results among studies and an overall lack of microbiologic data in clinical therapeutic trials, numerous issues related to treatment of human bartonella infection remains controversial. In contrast to the apparent lack of response to antimicrobial treatment in human CSD patients, bacillary angiomatosis, parenchymal bacillary peliosis, and acute bartonella bacteremia appear to respond to antimicrobial treatment, particularly in immunocompromised individuals. Doxycycline, erythromycin, and rifampin are recommended antibiotics, but clinical improvement has been reported following the use of penicillin, gentamicin, ceftriaxone, ciprofloxacin, and azithromycin.

Extractions: Microscopically, this is well circumscribed lesion which is usually present within a blood vessel (commonly thin-walled vein). Multiple small, delicate papillary structures project into the lumen and these are associated with some thrombus. These papillae are lined by single layer of plump endothelial cells surrounding a collagenized core. There is no multilayering, tufting, solid areas,necrosis and little or no atypia. There is little evidence of mitoses. In the early lesions the the papillae are composed of fibrin. In the late stage there is clumping and fusion of papillae forming an anastomosing network of blood vessel set in a loose meshlike connective tissue.
Extractions: December 28, 1997 Cat owners, homeless people, and people living with HIV disease are all at risk for infection with a tiny bacterium that can cause a wide variety of health problems, according to the largest study to date of infected individuals. The bug is known as Bartonella, according to a report in the current issue of The New England Journal of Medicine. One particular type, B. henselae , is carried by fleas and can cause cat scratch disease, a relatively mild illness that strikes 40,000 people in the U.S. every year. It causes swollen lymph nodes, fever and malaise after a cat bite or scratch. A second strain, known as B. quintana , is carried by lice, and is found more often in homeless individuals and others exposed to head or body lice. B. quintana can cause "trench fever," a relapsing fever that earned its name from an epidemic that struck thousands of soldiers during World War I. And either strain spells disaster for people with HIV/AIDS or anyone with a compromised immune system who gets infected, the study says. In that case, the bacteria can cause bacillary angiomatosis, a Kaposi's sarcoma-like disease where lesions form in the skin, bone and brain; or bacillary peliosis, where lesions form in the liver or spleen. Indeed, it wasn't until people with AIDS began coming down with the disorders, that doctors discovered that

B. henselae had initially been linked to bacillary angiomatosis (BA), a vascular proliferative disease most commonly associated with long-standing human immunodeficiency virus (HIV) infection or other significant immunosuppression. B. henselae has also been associated with bacillary peliosis, relapsing bacteraemia and endocarditis in humans. Cats are healthy carriers of B. henselae , and can be bacteraemic for months or years. It has recently been demonstrated that B. henselae can be transmitted from cat to cat by the cat flea, but not by direct contact between animals. The author discusses the present state of knowledge on the aetiology, clinical features and epidemiological characteristics of cat-scratch disease and bacillary angiomatosis.

He had been recently discharged from an outside hospital with a diagnosis of fever of unknown origin and a hematocrit of 29%. Initial workup revealed a hematocrit of 22%. The patient owns a cat, and reports playing with a friends kitten several months ago. Bacterial, AFB, and fungal cultures were all negative. An abdominal CT revealed hepatomegaly with punctate echogenic foci in the liver and spleen, raising the possibility of peliosis hepatis. Empiric therapy was begun. Serologies for Bartonella henselae were positive at 1:256, and a liver biopsy revealed dilated vascular spaces and focal lymphoplasmacytic inflammation. Special stains for organisms were negative.

BA was initially described in the skin, but can occur in a variety of organs or as septicemia.

Most patients respond to oral nystatin suspensions. If thrush is severe or if oesophageal or vaginal candidiasis is also present an oral azole like fluconazole can be used. In advanced HIV disease, low gastric acidity is often present and reduces the absorption of imidazole antifungal therapies such as ketoconazole and itraconazole. Oral hairy leukoplakia More than 90% of patients will have oral candidiasis at some stage of their disease, most commonly at low CD4+ counts.
