Gastrointestinal stromal tumor of esophagus

📋Clinical Description

This code identifies a malignant mesenchymal tumor originating from the interstitial cells of Cajal within the esophagus. These tumors are distinct from other sarcomas and carcinomas, characterized by specific immunohistochemical markers.

🎯When to Use

Apply this code when documentation confirms a diagnosis of gastrointestinal stromal tumor (GIST) specifically located in the esophagus. Pathological reports confirming GIST and its esophageal origin are essential for accurate coding.

💡Coding Tips

Differentiate from other esophageal malignancies like adenocarcinoma or squamous cell carcinoma.
Ensure the documentation explicitly states "esophagus" as the primary site; do not use for GISTs of other GI organs.
Confirm the diagnosis is a primary malignant neoplasm, not a metastatic lesion.
