FDG PET/CT Showing a Primary Vaginal NK/T Cell Lymphoma

A 28-year-old woman with vaginal discharge was admitted to the hospital. Colposcopy examination found several ulcers with pus in the vagina. Biopsy demonstrated extranodal natural killer/T-cell lymphoma. PET/CT scan was subsequently performed for staging. It revealed intense FDG uptake in the vagina. No FDG-avid lesion was seen in the rest of the body. A primary vaginal extranodal natural killer/T-cell lymphoma was diagnosed.
