A 72-year-old man who was receiving warfarin treatment for atrial fibrillation presented with hematemesis associated with retrosternal discomfort. He had swallowed a chicken bone 11 days before presentation. Hemodynamically, the patient was stable. The hemoglobin level was normal, but both the prothrombin time and the international normalized ratio were prolonged. Electrocardiography showed atrial fibrillation, with no ischemic changes. Endoscopy revealed an extensive longitudinal lesion with a bluish hue in the esophagus, extending from just beyond the upper esophageal sphincter to the gastroesophageal junction. It appeared as an elevated plaque bulging into the lumen of the esophagus (Figure [1]). Contrast-enhanced computed tomography (CT) demonstrated a concentric mural thickening along the entire length of the thoracic esophagus (Figure [2]). A diagnosis of esophageal hematoma was made. Warfarin treatment was stopped, and the patient was kept on a nothing-by-mouth regimen. A liquid diet was resumed 3 days later, and he was discharged free of symptoms after 9 days. The hematoma had regressed completely at endoscopy 8 weeks later (Figure [3]).

Esophageal hematoma, a rare clinical entity, is part of the spectrum of esophageal injury. It can mimic other more serious or life-threatening conditions in various clinical aspects. The appearance at endoscopy can be mistaken for an esophageal malignancy or an aortoesophageal fistula from an aortic aneurysm [1]
[2]. Contrast-enhanced CT is useful to exclude aortic pathologies [3]. However, the CT findings may be misinterpreted as a neoplasm by less experienced examiners [2]. Obtaining biopsy specimens from the lesion can lead to grave consequences, such as bleeding and perforation [4]. Misdiagnosis can occur when esophageal hematoma presents with acute chest pain. The acute onset and nature of the pain resemble that of aortic dissection, myocardial infarction, or pulmonary embolism [2]
[4]. Awareness and recognition of this entity is critical, because conservative treatment is the mainstay of management; further invasive investigations or treatments are potentially dangerous.
