Pulmonary Parenchymal Lymphoma Diagnosed by Bronchoscopic Cryoprobe Lung Biopsy

摘要

Summary: A 51-year-old man presented with progressively worsening lung infiltrates and respiratory failure. Extensive investigations including broncho-scopy with bronchoalveolar lavage and conventional transbronchial forceps biopsies failed to establish the diagnosis. After transfer to our institution, he underwent repeat bronchoscopy with transbronchial cryo-biopsy, which provided large, high-quality biopsy specimens establishing the diagnosis of parenchymal diffuse large B-cell lymphoma.
