[Comment on "Chinese expert consensus on the pathological diagnosis of interstitial lung disease with transbronchial lung cryobiopsy specimens"].

As one of the pathological biopsy methods, the transbronchial lung cryobiopsy (TBLC) for interstitial lung disease has been widely used in clinical practice. While TBLC causes less trauma or complications for patients than surgical lung biopsy (SLB), pathologists are sometimes less confident in making diagnosis due to the smaller specimen size of TBLC. In an effort to alleviate the problem, this issue of the journal published "Chinese expert consensus on the pathological diagnosis of interstitial lung disease with transbronchial lung cryobiopsy specimens". The consensus addressed issues related to TBLC delivery, quality evaluation, artificial phenomena, and pathological diagnostic principles. More importantly, physicians and pathologists need to work together to improve the diagnosis of TBLC.
