Apixaban-Induced Pseudo-Ludwig's Angina.

Ludwig's angina describes fulminant cellulitis involving the oro- and hypopharynx, which typically stems from bacterial pathogens, whereas "pseudo-Ludwig's angina" is ascribed to sublingual swelling due to noninfectious causes. There is a paucity of case reports implicating warfarin as the culprit for sublingual hematoma mimicking Ludwig's angina; however, we describe a novel case of apixaban-induced pseudo-Ludwig's angina, which was successfully managed with urgent surgical intervention and supportive care with antibiotic and glucocorticoid therapy.
