title: HIV-negative case of bacillary angiomatosis with chronic hepatitis B.
abstract: 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.
