Guidelines have recommended endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine-needle aspiration biopsy as initial sampling approaches of mediastinal lymph nodes for lung cancer staging. However, the small sample volume might restrict the diagnostic utility of needle aspiration in certain mediastinal diseases. We have recently shown that transbronchial mediastinal cryobiopsy, which is capable of providing larger amounts of intact tissue, improves diagnostic yield in rare tumors and benign diseases compared to EBUS-TBNA. Here, we present a case of mediastinal nodular lymphocyte predominant Hodgkin lymphoma successfully diagnosed by endoscopic transesophageal cryobiopsy.
