Cat scratch disease is a subacute regional lymphadenitis usually preceded by a history of being scratched by a cat or young kitten. The spectrum of illness ranges from mild self-limited adenopathy to severe systemic disease, including hepatosplenomegaly, encephalopathy, osteolytic lesions, splenic abscesses, mediastinal masses, and neuroretinitis. Vision loss is a rare complication of the disease. The authors report a patient with cat scratch disease associated with acute febrile illness, lymphocytic meningitis, and acute vision loss secondary to neuroretinitis. To their knowledge, this is the first ophthalmic case reported in which the diagnosis is supported by both a positive skin test and positive histopathology.

Bacillary angiomatosis is an opportunistic infection with systemic manifestations. Although most cases have occurred in human immunodeficiency virus-positive patients, other immunosuppressed patients, and even seemingly immunocompetent individuals, can become infected. In addition to the well-characterized cutaneous manifestations, visceral involvement can occur and may be the only locus of infection. Lymphadenopathy, bone or soft-tissue masses, fever, and hepatosplenomegaly can be presenting signs. The causative bacterium is still unidentified, but resemblances to the rickettsiae, Rochilamea quintana, the recently identified cat-scratch disease bacillus, and Bartonella bacilliformis have been noted by various investigators. Systemic disease is treatable and can be cured with antibiotic therapy.

An unusual case of cat scratch disease with large hepatic defects is presented. We describe a previously healthy 16-yr-old black man presenting with a neck mass, hepatosplenomegaly, and systemic symptoms. Pathology of the neck mass revealed a lymph node with chronic inflammation and focal necrosis. An abnormal computed tomography scan showed large hepatic defects which were confirmed at peritoneoscopy; biopsy specimens are described. Routine and special stains for bacteria and fungi were all negative. Serologic studies were unremarkable but a cat scratch skin test was positive. Follow-up examinations revealed resolution of all findings. Cat scratch disease should be considered in the differential diagnosis of diseases causing lymphadenopathy, systemic symptoms, and hepatic (and splenic) defects.

Cat-scratch disease is a common infection that usually presents as tender lymphadenopathy. It should be included in the differential diagnosis of fever of unknown origin and any lymphadenopathy syndrome. Asymptomatic, bacteremic cats with Bartonella henselae in their saliva serve as vectors by biting and clawing the skin. Cat fleas are responsible for horizontal transmission of the disease from cat to cat, and on occasion, arthropod vectors (fleas or ticks) may transmit the disease to humans. Cat-scratch disease is commonly diagnosed in children, but adults can present with it as well. The causative microorganism, B. henselae, is difficult to culture. Diagnosis is most often arrived at by obtaining a history of exposure to cats and a serologic test with high titers (greater than 1:256) of immunoglobulin G antibody to B. henselae. Most cases of cat-scratch disease are self-limited and do not require antibiotic treatment. If an antibiotic is chosen, azithromycin has been shown in one small study to speed recovery. Infrequently, cat-scratch disease may present in a more disseminated form with hepatosplenomegaly or meningoencephalitis, or with bacillary angiomatosis in patients with AIDS.
