Bacillary angiomatosis is a cutaneous or visceral infection with Bartonella henselae or Bartonella quintana. Cases usually occur in HIV infected individuals. We present a 60-year-old man with chronic lymphocytic leukemia and neutropenic fever caused by bacillary angiomatosis. The nine BA cases in oncology patients are reviewed.

Bacillary angiomatosis (BA) is an infectious disease which occurs predominantly in immunosuppressive patients and rarely in immunocompetent individuals. We had a case of BA who presented with a red cutaneous nodule on his left leg of which histopathological examination revealed marked lobular proliferation of capillaries throughout the interstitium and clusters of bacilli with hematoxylin-eosin and Warthin-Starry stains, respectively. Antibody titer against Bartonella henselae was 1/32. The only systemic disease the patient had was chronic hepatitis B. HIV was negative and no other immunosuppressive status was established. In this case we believe that the immunological differences secondary to chronic hepatitis B could have caused a tendency for the disease development.

It is a report of disseminated bacillary angiomatosis (BA) in a 23-year-old female patient, who is HIV-positive and with fever, weight loss, hepatomegaly, ascites, and papular-nodular skin lesions. The clinical and diagnostic aspects involved in the case were discussed. Bacillary angiomatosis must always be considered in the diagnosis of febrile cutaneous manifestations in AIDS.

Bacillary angiomatosis mainly affects the HIV-infected population. Information is limited on the evolution of bacillary angiomatosis during immune restoration following initiation of HAART. We report an unusual case of fatal Bartonella quintana bacillary angiomatosis occurring in an HIV-infected man during the immune restoration phase.

Bacillary angiomatosis is a rare opportunistic infection caused by the gram-negative bacteria Bartonella. The infection is strongly related to human immunodeficiency virus (HIV) infection, and hence, the diagnosis is usually considered based on the fact that the patient is HIV positive. We report on a case of bacillary angiomatosis presenting as a pyogenic granuloma of the hand in an otherwise apparently healthy man. The report is aimed to increase the awareness of hand surgeons that this serious disease may be the first clinical manifestation of HIV infection. The case also demonstrates that once the correct diagnosis is made, medical treatment alone may be sufficient to cure massive recurrent lesions.

Bacillary angiomatosis is an unusual infectious disease, with angioproliferative lesions, typical of immunocompromised patients. It is caused by Bartonella quintana and Bartonella henselae, two infectious agents of the genus Bartonella, which trigger variable clinical manifestations, including cutaneous vascular and purpuric lesions, and regional lymphadenopathy, and even a systemic disease with visceral involvement. We report a 38-year-old HIV positive male presenting with a history of six months of cutaneous growing purple angiomatous lesions, located also in nasal fossae, rhi-nopharynx and larynx. The skin biopsy was compatible with bacillary angiomatosis. Polymerase chain reaction of a tissue sample showed homology with B. quintana strain Toulouse. The patient was treated with azithromycin and ciprofloxacin with a favorable evolution.

Bacillary angiomatosis is an infectious disease caused by two Gram-negative bacilli; this disease usually affects immunosuppressed hosts with a history of cat scratch. We report a rare case of bacillary angiomatosis in an immunocompetent 26-year-old woman with no history of exposure to cats, and with atypical clinical features (very pruritic vascular papules and nodules with ulceration and hemorrhage on the right arm and fingers). She was successfully treated with clarithromycin for 3 months. Bacillary angiomatosis must be kept in mind in the differential diagnosis of any papules and nodules in cases of unknown etiology and also in immunocompetent patients and HIV-negative individual.

Bacillary angiomatosis (BA) is an angioproliferative disease of immunocompromised patients that usually presents as vascular tumors in the skin and subcutaneous tissues. It is caused by chronic infections with either Bartonella henselae or B. quintana. Oral cavity BA is exceedingly rare and even rarer without simultaneous cutaneous disease. We report herein the case of a 51-year-old HIV-infected man who presented severe odynophagia and an eroded lesion on the hard palate that progressed to an oronasal fistula. No cutaneous lesions were recorded. Doxycycline led to complete resolution. To the best of our knowledge, only six previous cases of oral BA without tegumentary disease have been previously reported and none of them progressed to fistula.

Bacillary angiomatosis represents a cutaneous and systemic infection caused by Bartonella species, typically described in the past in HIV-positive patients or associated with immunodeficiencies. More recent case reports had brought into attention the probability that this entity may manifest in otherwise healthy individuals, triggered by trauma and skin burns. The physiopathology of this neoproliferative process is based on the production of angiogenetic molecules, such as vascular endothelial growth factor (VEGF) and IL-8. In case of an inadequate treatment, the evolution can be fatal, with a systemic dissemination of the abscesses within the gastro-intestinal tract, respiratory tract, brain and bones. The appropriate therapy is with oral erythromycin and doxycycline, but several treatments such as cephalosporins, penicillins, macrolides, aminoglycosides, rifampin, dapsone, ciprofloxacin, have been tried with favorable results. Herein we present the case of a Caucasian patient, seronegative for HIV, who developed multiple vascular papules and nodules on the face, after a severe trauma and which healed after an adequate antibiotic therapy with oral clarithromycin.
