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