title: [Disseminated histoplasmosis after a tropical visit in a patient with known sarcoidosis].
abstract: A 40-year-old man with grade II sarcoidosis went on a two-week visit to Ecuador. Afterwards he was treated with low-dose corticosteroids because of slight deterioration on the X-ray film. Unilateral hilar enlargement followed by bouts of high fever and a greatly increased erythrocyte sedimentation rate, suggested an acute exacerbation of the sarcoidosis and was, therefore, treated with an increase in steroid dosage plus azathioprine. Bronchoalveolar lavage fluid and tissue samples from lung, bone-marrow and spleen were suggestive of an infection with Histoplasma capsulatum. There was now bilateral hilar enlargement with right upper lobe infiltration, marked hepatosplenomegaly and thrombocytopenia (17,000/microliters), but serological tests remained negative. The fulminant course with dissemination could not be arrested despite administration of fluconazole (400 mg/d) and amphotericin B (total dosage 1.14 g). Histoplasma capsulatum was cultured from lung and spleen tissue post-mortem.
