TWO CASES OF ESOPHAGEAL PAPILLOMA

-USING THE ULTRASONHC ENDOSCOPE AND THE ELECTRONIC ENDOSCOPE-

Abstract

Two cases of esophageal papilloma were reported. Case 1. A 67-year-old male patient was admitted to our hospital, complaining of abdominal fullness. Upper GI series and endoscopic examination revealed a protruded lesion covered with a granular surface in the middle esophagus. In application of ultrasonic endoscope, we could correctly diagnose the width and depth of the lesion. Furthermore, the electronic endoscope by means of the method of "WATER LOADING" was useful for judgement of its form. The size of the resected tumor by endoscopic polypectomy was 7 × 2 × 8mm. Histological finding disclosed esophageal squamous cell papilloma. Case 2. A 71-year-old female was admitted to our institution with a complaint of epigastric discomfort. Upper GI series and endoscopic examination revealed a polypoid lesion of Yamadatype III in the lower esophagus. The biopsy specimens showed esophageal squamous cell papilloma. The esophageal papilloma was treated by laser, because of inadequate condition such as heart failure with arrhythmia for endoscopic polypectomy. To our knowledge, only 27 cases of esophageal papilloma have been reported in Japan including our 2 cases. However, it seems that esophageal papilloma will be potentially malignant. Therefore, it is absolutely necessary to collect suitable number of cases and follow these cases for long term.
