title: [A case of primary HIV-1 infection].
abstract: A previously healthy 28 year old Japanese man came to us with a genital ulcer which appeared 13 days before admission to our hospital. He had subsequently fever (40 degrees C), arthralgia, a sore throat and oral aphtha 6 days before admission. He had a history of sexual contact with a female commercial sex worker one week before his illness. On the day of admission, he had shallow ulcers on the lip, tongue and penis. Initial laboratory test included leukopenia and thrombocytopenia. His fever abated 3 days after admission. His condition and bicytopenia recovered completely after 12 days of admission. Although, his serum HIV-1 antibody was negative when he was admitted, 3 months later the antibody was seroconverted. And p24 antigen and HIV-1 RNA of stocked serum were positive. Diagnosis of primary HIV-1 infection was made. Recently, HIV-1 infection has been increasing in Japan. Consideration of this disease in differential diagnosis of acute febrile illness is necessary.
