Histoplasmosis during childhood.

Abstract

To define the clinical presentation of histoplasmosis among hospitalized children, we reviewed the charts of patients treated for histoplasmosis at Vanderbilt University Children's Hospital during the years 1968 through 1988. Thirty-five patients with histoplasmosis diagnosed by culture, pathologic examination, or serologic testing were identified, including 29 patients (83%) with pulmonary/mediastinal infection, 5 (14%) with disseminated disease, and 1 (3%) with primary cutaneous histoplasmosis. The most common symptoms included fever, present in 26 patients (74%), and cough, present in 20 (57%). Of 26 patients with fever, 18 (69%) had fever of > 2 weeks' duration and 7 (27%) had temperatures > or = 40.5 degrees C (> or = 105 degrees F). Abnormal physical findings were few, but 19 patients (54%) had wheezing. Chest radiographs were obtained in all cases except one; 31 (91%) showed abnormalities, including adenopathy in 25 cases (74%) and infiltrates in 19 (56%). Histoplasmin skin tests were positive for 22 (96%) of the 23 patients tested. No cases of classic disseminated histoplasmosis of infancy were identified. Histoplasmosis should be considered in the differential diagnosis when children living in endemic areas are evaluated for persistent fever, cough, and/or wheezing, particularly if adenopathy is seen on the chest radiograph.
