title: Sputum cytodiagnosis of disseminated histiocytic lymphoma. A case report.
abstract: Cytohistologic evidence of pulmonary involvement with histiocytic lymphoma was discovered in a patient nine years after the original clinical diagnosis was made. The positive sputum cytologic diagnosis confirmed the radiologic impression of pulmonary involvement, which was substantiated by an open lung biopsy. This case report demonstrates the value of periodic sputum cytology in the diagnosis and management of histiocytic lymphoma. Sputum cytology should be utilized more frequently in the monitoring of pulmonary histiocytic lymphoma.
