[Pulmonary involvement in chronic lymphocytic leukemia. Diagnostic value of trans-bronchial biopsy (author's transl)]

Pulmonary parenchymatous involvement in a patient with chronic lymphocytic leukemia (CLL) was demonstrated by trans-bronchial pulmonary biopsy using a flexible endoscope. This procedure is clearly of value in similar cases when clinical and roentgenological examinations are insufficient. The observed cases provides the opportunity for a brief chronological review of the literature. Advances in the classification of CLL, which follow the technological improvements, are described as well as their bearing on management and prognosis of this condition.
