Vitamin K antagonists (VKAs) are oral anticoagulants, widely used for the prevention of thromboembolic diseases, but their use carries certain risks. The main complication of these anticoagulants is bleeding, requiring a careful balance of benefit versus risk and strict monitoring of the international normalized ratio (INR). Bleeding is most commonly seen in the gastrointestinal, genitourinary, and cerebral systems. Localization in the upper aerodigestive tract is very rare, with cases of retropharyngeal, laryngeal, and/or sublingual involvement reported in the literature. We describe here an exceptionally rare case of bilateral tonsils hemorrhage related to VKAs in a 58-year-old woman undergoing treatment with acenocoumarol (Sintrom) for atrial fibrillation
