Obstructing esophageal hematoma mimicking cancer: a case report and experimental study.

In this paper the 10th case of esophageal hematoma, a rare variant of the Mallory-Weiss syndrome, is reported. The radiographic study strongly suggested an obstructing neoplasm, however, this hematoma disappeared within five days and this same rapid disappearance was noted in dogs in which esophageal hematomas were induced. Fiberoptic esophagoscopy provides a clue to the diagnosis since the mural hematoma is differentiated from carcinoma by its dark color.
