  "abstract": "An 80-year-old man with cerebral infarction and no neurological deficits was hospitalised for right empyema. Although the patient’s condition improved with antimicrobial therapy and right thoracic drainage, a swelling in his right cheek was observed during clinical rounds. Oral examination revealed ulceration on the right buccal mucosa ( figure 1A) with an embedded blue solid matter (figure 1B), which was removed. After confirming the history of prescribed medications, the removed matter was determined to be a dabigatran capsule (figure 1C), and oral ulcer due to dabigatran was suspected. With conservative measures, re-epithelialisation was achieved within 2 weeks.",
