Abstract

We report a case of cat scratch disease (CSD) with neck lymphadenopathy. A 23-year-old woman reporting a painless left upper neck mass showed no inflammatory sign. Positron emission tomography (PET) showed fluorodeoxyglucose (FDG) accumulation in the neck suggesting malignant lymphoma. Biopsy of a resected lymph node histopathologically indicated granulomatous lymphadenitis with a suppurative granuloma. Serological indirect fluorescent antibody (IFA) findings showed elevated Barthonella henselae IgM antibody, yielding a definitive diagnosis of CSD. Serological testing for Barthonella species is important in diagnosing this zoonotic infection.
