We report the case of a human immunodeficiency virus (HIV)-seronegative patient with untreated rheumatoid arthritis (RA), who developed fatal PCP related to uncommon CD4+ T-lymphocytopenia. Although extremely rare and of uncertain aetiology, suppression of cellular immunity and subsequent opportunistic infections should be suspected in such patients. ER -
