A 66-year-old man was hospitalized after vomiting blood after inducing vomiting using his fingers due to laryngeal discomfort. Upper digestive tract endoscopy revealed a large, dark red mass that connected from the upper esophagus to the lower esophagus. Esophageal submucosal hematoma was diagnosed using endoscopy, X-ray images, a small-diameter ultrasonic probe, and chest CT scanning. Pain from the epigastrium to the larynx disappeared after 3 days. Melena occurred on Day 3. Endoscopic examination revealed that the hematoma had collapsed over a wide area. Endoscopic examination after one week showed that the mucous membrane covering the hematoma had peeled away revealing an extensive shallow ulcer in the esophagus. Endoscopic examination after one month confirmed the ulcer had scarred and healed.
