[Gastrointestinal stromal tumor of the esophagus]
Abstract:
The paper describes a rare case of a stromal tumor of the esophagus in a 68-year-old male who was initially diagnosed as having esophageal leiomyoma after biopsy and study of a surgical material. Stromal tumour could be diagnosed by immunohistochemical (positive expression of oncomarkers; CD117, CD34, vimentin, CD99, and GFAP) and molecular genetic (real-time PCR) studies. This case confirms that it is necessary to use an immunohistochemical study in patients with spindle-cell tumors of the gastrointestinal tract.
