Chest-wall abscess due to cat-scratch disease (CSD) in an adult with antibodies to Bartonella clarridgeiae: case report and review of the thoracopulmonary manifestations of CSD.

We describe a patient who presented with a massive chest-wall abscess after a severe debilitating illness that lasted 3 months. Steroid therapy, administered for 4 weeks, masked the slow development of an extensive axillary and chest-wall abscess. After multiple negative tests, the patient's prolonged illness was diagnosed as cat-scratch disease (CSD). An indirect fluorescent antibody test revealed that two convalescent serum samples were positive for IgG to Bartonella clarridgeiae, but no other Bartonella species. We also review 12 cases of severe chest and pulmonary disease due to CSD that were reported in the English-language literature. Thoracopulmonary findings associated with CSD, pathogenic mechanisms of bartonella infections, diagnostic criteria, and management of CSD are presented.

Cervical cat scratch disease lymphadenitis in a patient with immunoglobulin M antibodies to Toxoplasma gondii.

We report on a young patient with chronic cervical lymphadenopathy and serological and histological evidence for infection with Bartonella henselae and Toxoplasma gondii. Serological follow-up studies, including testing for avidity of Toxoplasma-specific immunoglobulin G antibodies, assisted in the determination of the cause of the acute lymphadenitis. Our results suggest that the clinical symptoms were most likely due to cat scratch disease rather than to acute toxoplasmosis.

PET scan-positive cat scratch disease in a patient with T cell lymphoblastic lymphoma.

In patients who have history of lymphoma, a positive positron emission tomography (PET) scan is frequently considered as good evidence for relapse and/or persistent disease. Thus, lymph node biopsy is not always done to confirm the diagnosis of relapse or refractory lymphoma before a patient is subjected to further chemotherapy. We report a case of patient with history of T cell lymphoblastic lymphoma who presented again with inguinal lymphadenopathy and positive study on positron emission tomography suggestive of lymphoma relapse. This was pathologically proven to be cat scratch disease. This case suggests that in the immunocompromised patients who had history of lymphoma, infectious etiology should be ruled out for PET scan-positive lymphadenopathy.

[Multifocal chorioretinitis, papillitis, and recurrent optic neuritis in cat-scratch disease].

To evaluate the causative factor for multifocal chorioretinitis, papillitis, and recurrent optic neuritis. A 41-year-old patient presenting multifocal choroiditis, papillitis, and recurrent optic neuritis was evaluated with funduscopy, angiography (FA), optical coherence tomography (OCT), visual evoked potentials (VEP), and numerous blood laboratory tests. FA and OCT showed multifocal pigment epithelial detachments. VEP showed typical changes for optic neuritis and papillitis. Indirect fluorescent antibody assay disclosed Bartonella henselae. Although cat-scratch disease frequently presents with optic neuritis or neuroretinitis, additional multifocal chorioretinal lesions associated with serous pigment epithelial detachments may occur. In case of recurrent episodes, a detailed laboratory work-up is mandatory to define the appropriate diagnosis and treatment.
