Introduction
In general, high-grade squamous intraepithelial lesion of the esophagus refers to dysplastic changes in the esophageal mucosa that involve or nearly involve the full thickness of the epithelium. High-grade squamous intraepithelial lesion is considered a precancerous condition. This finding may indicate severe atypical hyperplasia of the esophageal squamous epithelium, in which abnormal cells have not breached the basement membrane and have not invaded into the underlying stroma.
In general, high-grade squamous intraepithelial lesion of the esophagus refers to dysplastic changes in the esophageal mucosa that involve or nearly involve the full thickness of the epithelium. A detailed analysis is as follows:
High-grade squamous intraepithelial lesion of the esophagus is considered a precancerous condition. This finding may indicate severe atypical hyperplasia in the esophageal squamous epithelium, in which abnormal cells have not breached the basement membrane and have not invaded the underlying stroma. It may result from damage to the esophageal mucosal layer or long-term erosion, leading to cellular changes within the epithelium. This can potentially cause mucosal rupture and bleeding, resulting in symptoms such as dysphagia, hematemesis, and melena.
If patients experience any discomfort, they should promptly seek medical attention at a qualified hospital. Under the guidance of a physician, treatment options such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) may be performed. Following surgery, additional therapies such as chemotherapy or radiotherapy may be recommended in combination to help control disease progression and improve the patient's quality of life.
Patients experiencing symptoms should seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
