Rapid Onset of Pulmonary Infiltration Due to Histiocytic Lymphoma

Abstract

Five cases demonstrating the rapid onset of pulmonary infiltrates due to hystiocytic lymphoma are presented. In four cases the pulmonary infiltrate occurred at the time of initial presentation and the fifth case occurred 2½ months after the original diagnosis. The radiographic manifestations are nonspecific. Lung biopsy, open or closed, is needed to confirm the diagnosis before initiating appropriate therapy.
