A Case of Lung Metastasis of Breast Cancer Diagnosed Using Ultrathin Bronchoscopic Cryobiopsy with a "Tube-wedging Method"

Abstract

A 64-year-old patient with a history of breast cancer was referred to our department after a computed tomography finding of a chest abnormality. We performed bronchoscopy, and the specimens obtained via forceps biopsy were nondiagnostic. Cryobiopsy was then performed using the "tube-wedging method." The process was straightforward and could be completed without complication. Pathological diagnosis of specimens obtained via cryobiopsy revealed metastatic breast cancer in the lungs.
