Esophageal squamous cell carcinoma

Esophageal squamous cell carcinoma is a primary malignant epithelial neoplasm arising from the stratified squamous epithelium that lines the lumen of the esophagus, most frequently involving the upper and middle thoracic thirds Pathophysiologically, chronic mucosal injury—often driven by significant tobacco use, heavy alcohol consumption, nutritional deficiencies, or chronic thermal irritation—induces dysplastic progression that invades the submucosa, muscularis propria, and adjacent mediastinal...

Pathophysiologically, chronic mucosal injury—often driven by significant tobacco use, heavy alcohol consumption, nutritional deficiencies, or chronic thermal irritation—induces dysplastic progression that invades the submucosa, muscularis propria, and adjacent mediastinal structures

Clinically, affected patients are typically older adults who present late in the disease course with progressive dysphagia, odynophagia, unintentional weight loss, and potential complications from regional lymph node metastasis or local invasion
