Esophageal sarcoma

Esophageal sarcoma is a malignant tumor derived from mesenchymal tissue, accounting for about 8% of gastrointestinal sarcomas, and about 0.5% of esophageal malignancies. According to histological characteristics, esophageal sarcoma includes leiomyoma, fibrosarcoma, rhabdomyosarcoma, osteosarcoma, and Kaposi sarcoma in immunodeficiency patients. Among them, fibrosarcoma is the most common, accounting for half of esophageal sarcomas. There are two types of esophageal sarcomas: polyp and invasive. Polyps are more common clinically, and their tumors are large in size, protrude into the esophagus, develop and metastasize later, and have a high resection rate.
