title: Unusual manifestations of histoplasmosis in childhood.
abstract: Nine previously healthy children were seen with unique, and in several instances, unreported manifestations of acute histoplasmosis. Presenting manifestations included: obstructive airway disease; subacute parotitis; unilateral cervical lymphadenopathy; anterior mediastinal mass-simulating neoplasm; immune hemolytic anemia; a cutaneous lesion with regional lymphadenopathy; mediastinal mass and pericardial effusion; pulmonary infarction; and a symptom complex of cervical lymphadenopathy, CSF pleocytosis, arthritis, and interstitial nephritis. In eight children histoplasmosis was not initially considered, and the correct diagnosis was made only after complex, and sometimes invasive, diagnostic evaluation and considerable delay. All patients recovered fully without antifungal therapy. Reports of uncontrolled trials of new antifungal agents for treatment of histoplasmosis in immunocompetent hosts should be cautiously evaluated.
