Over the last decade transbronchial lung cryobiopsy (TBLC) has proven to be an "innovative application" of an "old procedure" for the histologic diagnosis of diffuse interstitial lung diseases (DILDs). Thus, the technique of TBL cryobiopsy is now adopted for diagnostic purposes, transbronchially in peripheral airways to sample lung parenchyma, whereas this same technique was traditionally employed in the past for therapeutic purposes, essentially for the management of malignant obstruction of central airways. When patients with interstitial lung diseases (ILDs) need histopathological data in their diagnostic pathway, this bioptic approach could be a valid alternative to surgical lung biopsy, that is still the gold standard at the moment. ⋯ The technical aspects are really important, and they still need a complete standardization. TBL cryobiopsy should be part of an equipment of the modern interventional pulmonologist, who should know indications and contraindications of this methodic and the technical aspects of the procedure. This is a complex procedure requiring to be performed by endoscopists working in specialized centers with specific knowledge of DILDs, and a multidisciplinary approach, which represent pre-requisites for admission to training in this procedure.
