[Puzzling B symptoms in a 61-year-old patient under treatment for rheumatoid arthritis]. / Rätselhafte B-Symptomatik bei einem 61-Jährigen unter Therapie einer rheumatoiden Arthritis.

A patient with rheumatoid arthritis and immunosuppression developed symptoms of wasting, neuropathy and lung cavitations eventually leading to central nervous system symptoms and fatal multi-organ failure. Disseminated infection with Histoplasma capsulatum proved to be the underlying cause. The primary infection had apparently been acquired 4 years earlier on a holiday to the Caribbean. Rare infectious diseases should be considered in patients under immunosuppression and travel activities to specific endemic areas.
