&NA;Bronchial needle aspiration (BNA) with or without core biopsy rarely leads to clinically significant hemorrhage. We report a case of persistent bleeding after a 19‐gauge BNA core biopsy of a necrotic mediastinal lymph node that began 5 days after the procedure and the reinstitution of anticoagulation. To my knowledge, this represents the first case of nonfatal hemorrhage after BNA which was severe enough to require transfusion with fresh‐frozen plasma. The origin of the hemorrhage appears to be multifactorial. The necrotic nature of the tissue specimen, the unusually large core biopsy site, and the effects of systemic anticoagulation may all have been contributing factors.
