title: [Stromal tumor of esophagus: case report].
abstract: Gastrointestinal stromal cell tumors (GIST) are rare neoplasms of the gastrointestinal tract, although they are the most common mesenchymal neoplasms. The stomach and small intestine are the most frequent site of involvement accounting for approximately 85% of cases. However, esophagus involvement is exceptional (<5%); indeed some large series fail to report it. Surgery resection is the cornerstone of treatment; currently imatinib has demonstrated its utility to reduce local recurrences and tumor mass. We report a 75 years-old male with a medical history of dysphagia who presented upper gastrointestinal bleeding caused by an esophageal GIST. The patient did not undergo surgery because of severe chronic heart failure.
