Abstract

A 56-year-old man was admitted to our hospital in December 1996 due to empyema thoracis. A laboratory examination revealed lymphocytopenia and CD4+ T lymphocytopenia (<300 cells/μl). No evidence for a human immunodeficiency virus (HIV) infection was found. No malignant, hematological or autoimmune disease was detected. We thus diagnosed this case as being idiopathic CD4+ T lymphocytopenia (ICL). During his hospital treatment, he was affected with cytomegaloviral retinitis and cured by therapy. His subsequent treatment went well without a recurrence of severe infection although a low CD4+ T lymphocyte count continued after the recovery from empyema thoracis.
