Spontaneous lingual and sublingual haematoma: A rare complication of warfarin use

Warfarin is commonly used for prevention of embolic events. Bleeding is the main side effect of warfarin. Lingual and sublingual haematoma are rare. In the literature, nine cases have so far been reported. We report the case of a 70-year-old Caucasian woman who developed spontaneous lingual and sublingual haematomas while on warfarin therapy. Spontaneous lingual and sublingual haematoma are rare, but can be potentially life-threatening complications as they cause airway obstruction. To the best of our knowledge, this is the first reported case of earliest haematoma after warfarin use. Copyright 2014 BMJ Publishing Group. All rights reserved.
