title: Schistosomiasis japonica identified by laparoscopic and colonoscopic examination.
abstract: A 45-year-old Philippine woman who came from Mindanao Island was admitted to our hospital with a complaint of epigastric discomfort. Abdominal ultrasonography and computed tomography demonstrated a network pattern and linear calcification in the liver. Laparoscopic examination showed numerous yellowish, small speckles over the liver surface. The liver surface was separated into many small blocks by groove-like depressions, demonstrating a so-called tortoise shell pattern. Conventional colonoscopy and narrow-band imaging showed irregular areas of yellowish mucosa, and diminished vascular network and increased irregular microvessels extending from the descending colon to the rectum. Liver biopsy showed many Schistosoma japonicum eggs in Glisson's capsule and colon biopsy showed many S. japonicum eggs in the submucosal layer. These findings established a diagnosis of schistosomiasis japonica. The present case is imported schistosomiasis japonica. Even though new cases have not occurred recently in Japan, we should remain aware of schistosomiasis japonica for patients who came from foreign epidemic areas.
