Malignant esophageal neoplasm

A malignant esophageal neoplasm refers to a primary cancer arising from the mucosal lining of the esophagus, primarily manifesting as either adenocarcinoma or squamous cell carcinoma Affecting the upper gastrointestinal tract and predominantly diagnosed in older adults and males, these tumors typically originate in the glandular tissue of the distal esophagus—often secondary to chronic gastroesophageal reflux disease and Barrett esophagus—or in the squamous epithelium of the upper and middle seg...

Pathophysiologically, neoplastic proliferation leads to progressive luminal obstruction and early local invasion through the esophageal wall, characteristically presenting with dysphagia, odynophagia, and unintentional weight loss

Pathophysiologically, neoplastic proliferation leads to progressive luminal obstruction and early local invasion through the esophageal wall, characteristically presenting with dysphagia, odynophagia, and unintentional weight loss Due to the absence of a true serosal layer and abundant lymphatic drainage, the disease carries a pronounced propensity for rapid transmural extension, regional lymph node involvement, and distant metastasis
