A 38-year-old man was admitted to our hospital with epigastric pain for the past 1 month. Upper GI endoscopy revealed antral gastritis, a 7-mm ulcer in the apical and a 6-mm ulcer in the posterior wall of the duodenal bulb. Pantoprazole 40 mg was given once daily. Two days later, he presented with an acute swelling of his neck. On examination, a large, nonfluctuant thyroid swelling was seen on the right side of the neck. His blood pressure, temperature, pulse rate, and respiratory rate were normal. Blood tests showed normal hemoglobin, international normalized ratio, and thyroid function tests. Ultrasonography of the neck revealed a 23 ×37 ×44-mm expanding hematoma located at the right thyroid gland.eninfo:eu-repo/semantics/closedAccessThyroid HematomaGastrointestinal EndoscopyUlcerEditorial10.1097/SGA.0000000000000191403248249285704252-s2.0-85020935702Q3WOS:000402526200008Q4
