Background: Cell blocks (CBs) from pleural fluid are frequently used in the practice of respiratory medicine, but there have been few reports on the use of CBs from forceps and brush washing fluid in bronchoscopy for pathological diagnosis. We retrospectively analyzed the usefulness of CBs from forceps and brush washing fluid. Patients and Methods: Patients who underwent bronchoscopy and had CBs made from forceps and brush washing fluid in bronchoscopy at our institution between June 2016 and May 2021 were included. Cases in which additional information was obtained from CBs were reviewed in detail. Results: In total, 138 patients had CBs made from forceps and brush washing fluid in bronchoscopy during the study period. EBUS-GS (endobronchial ultrasound-guide sheath) was used for 102 of these patients. The final diagnosis was lung cancer in 114 cases, infection disease in 10 cases, metastatic lung tumor in 8 cases, lymphoproliferative disease in 2 cases, sarcoidosis in 1 case, and organizing pneumonia in 1 case. There were 13 cases with additional information obtained from CBs, all of which were cases of malignant tumors. Conclusions: CBs from forceps and brush washing fluid in bronchoscopy were useful for pathological diagnosis in some cases.
