Abstract
<p>Background. Pleural biopsy during semiflexible thoracoscopy is useful for the diagnosis of pleural effusion. However, we sometimes experience cases in which the tumor is difficult to grasp with a flexible forceps because of the properties of the pleura. Case. The patient was a 51-year-old man with idiopathic interstitial pneumonia, who was found to have left pleural effusion. We attempted to perform pleural biopsy using a flexible forceps during semiflexible thoracoscopy; however, it was impossible because it was fibrous and hard lesion. Therefore, we performed thoracoscopic pleural biopsy with a cryoprobe. Cryobiopsy enabled us to obtain a specimen. A thoracic SMARCA4-deficient undifferentiated tumor was diagnosed based on the pathological findings. Conclusion. Pleural cryobiopsy during semiflexible thoracoscopy may be useful for the diagnosis of patients with an extensive fibrous pleura, in which the tumor is difficult to grasp with a flexible forceps.</p>
