Transbronchial cryobiopsy (TBCx) Transbronchial cryobiopsy (TBCx). a) Three fragments of TBCx measuring 18 mm2, 21 mm2 and 31 mm2 (total area of 70 mm2; low power of magnification, 4×). Transbronchial cryobiopsy (TBCx). a) Three fragments of TBCx measuring 18 mm2, 21 mm2 and 31 mm2 (total area of 70 mm2; low power of magnification, 4×). Biopsy was taken from the lower lobe of the right lung. The clinical case is briefly reported in figure 1. b) TBCx (high power of magnification, 40×) shows architectural distortion, patchy fibrosis and fibroblastic foci. Based on current American Thoracic Society/European Respiratory Society guidelines [16], pathologists identified a pattern of usual interstitial pneumonia with high confidence. This case of interstitial lung abnormalities is an example of a very early case of familial idiopathic pulmonary fibrosis. TBCx offers the opportunity to biopsy a wide range of patients [17], and its application in the field of early diagnosis of diffuse parenchymal lung diseases is of undoubted interest. However, treatment and follow-up of these patients are currently not standardised, and future studies and guidelines should focus on this subgroup of patients, which is currently largely under-recognised.
