This case report describes a condyloma acuminata with intense FDG uptake mimicking primary anorectal carcinoma in an HIV-infected patient. A 44-year-old HIV-positive homosexual man with a history of lymphoma underwent an 18F-FDG PET/CT for restaging. A focal intense hypermetabolic lesion around the anorectal area was found by the PET/CTand it was suggested as a tumorous lesion. However, the lesion was not detected on the contrastenhanced abdominal CT. Via a sigmoidoscopy, cauliflower-like masses were visualized in the intra-anal area. The tumorwas surgically excised and proven to be condyloma acuminata by permanent pathology.
