We report a case of acute retroviral syndrome presen-ting as a fever of unknown origin. A 22-year-old man was admitted to the hospital because of fever. He had been well untill 20 days earlier when he experienced fe-ver and headache. Three days before admission diarrhea, vomiting, sore throat and myalgia developed. Physical examination revealed skin rash, and multiple lymphadeno-pathy. Acute human immunodeficiency virus (HIV) infec- tion was confirmed by seroconversion. As the number of patients with HIV infection is increasing in Korea, acute retroviral syndrome should be included in the differential diagnosis of fever of unknown origin.
