Esophageal sarcoma

Esophageal sarcoma is a malignant tumor originating from mesenchymal tissue, accounting for about 8% of gastrointestinal sarcomas and about 0.5% of esophageal malignant tumors. According to histological characteristics, esophageal sarcoma includes leiomyosarcoma, fibrosarcoma, rhabdomyosarcoma, osteosarcoma, and Kaposi's sarcoma in immunocompromised patients. Among these, fibrosarcoma is the most common, accounting for half of esophageal sarcomas. Esophageal sarcoma has two gross types: polypoid and infiltrative. The polypoid type is more common clinically, with large tumor volume protruding into the esophageal lumen, late development and metastasis, and a high resectability rate.
