ABSTRACT |
Gastrointestinal stromal tumors (GISTs) predominate in the stomach and small intestine but have rarely been documented in the esophagus. We report a rare case of GIST of the esophagus in a 47-year-old woman. Histologically, the tumors showed a combination of solid, myxoid, and perivascular collar-like patterns, with spindle and epithelioid cells.
The tumor cells were positive for CD117, CD34, and S-100 protein and negative for desmin and -smooth muscle actin. |
Key Words:
Gastrointestinal stromal tumors; C kit proteins; CD34 antigen; Esophageal neoplasms |
