title: Histoplasmosis simulating lymphoma in children.
abstract: The experience of two Mineapolis hospitals with histoplasmosis over a 10-yr period was reviewed. Six of eleven pediatric patients with histoplasmosis presented with systemic symptoms, a mediastinal mass, and no pulmonary infiltrates. A clinical diagnosis of lymphoma was made in each case. Immediate radiation therapy for respiratory compromise was considered in one patient before pathologic diagnosis revealed primary histoplasmosis of the mediastinum. Although immediate therapy with steroids or irradiation is often considered in patients who have acute respiratory embarrassment caused by a mass, histologic confirmation of the diagnosis is always indicated before such therapy is instituted. Primary histoplasmosis of the mediastinum may be more common than previously thought.
