Abstract
An 88-year-old woman was referred to our hospital for the evaluation of the esophagealtumor, which was found by her family physician. Endoscopy demonstrated a round protrusionwith approximately about l cm in diameter on the thoracic segment of the esophagus.Histological diagnosis of the biopsy specimen was squamous cell carcinoma. The depth of thetumor invasion was found to be as deep as submucosa lay endoscopic ultrasonography. Sincethe patient and her families refused the treatment by surgical resection, endoscopic mucosalresection was perfarmed. The resected specimen was found to be an esophageal carcinoma of O-I pl. (plateau) type with the histblogy of mucoepidermoid carcinoma, a subtype ofadenosquamous carcinoma. The clinical course of the patient is uneventful and she shows nolocal recurrence and distant metastasis for more than five years after the endoscopic treatment. We report this rare case since endoscopic resection was useful for the treatmgnt ofesophageal mucoepidermoid carcinoma found in elderly case.
