[A retrospective endoscopic case of adenoid cystic carcinoma of the esophagus].

We report a case of a 64-year-old Japanese man with adenoid cystic carcinoma. An elevated lesion covered by intact epithelium in the thoracic esophagus was found in September, 2007 and been followed. After dysphagia appeared follow-up endoscopy was performed in January, 2010, and morphological change into a protruding tumor was recognized.

[A case of eosinophilic gastroenteritis with ring-like discoloration in the lower end of the esophagus].

We report the case of a 15-year-old Japanese boy with eosinophilic gastroenteritis. The patient complained of abdominal pain and watery diarrhea and had a history of allergic rhinitis. Laboratory data on admission showed leukocytosis with remarkable eosinophilia.

Clinical significance of primary lesion FDG uptake for choice between oesophagectomy and endoscopic submucosal dissection for resectable oesophageal squamous cell carcinomas.

Objectives: To correlate primary oesophageal squamous cell carcinoma (SCC) (18)F-fluoro-deoxyglucose (FDG) uptake with pathological factors and examine its significance regarding choice of therapy.

Methods: We retrospectively examined the factors affecting visible and non-visible FDG uptake in 37 primary lesions in 32 oesophageal SCC patients who underwent PET/CT before oesophagectomy or endoscopic submucosal dissection (ESD). We divided the lesions into pathological depth invasion ≥sm2 oesophagectomy (n = 18) and ≤sm1 ESD (n = 19) indicated groups and compared the diagnostic accuracy of FDG-PET with that of endoscopic ultrasound (EUS) performed for 23 superficial lesions to discriminate between these groups.

Early gastric carcinomas in the cardiac region: diagnosis with double-contrast x-ray studies.

Background: The ratio of early to advanced gastric carcinomas in the cardiac region is significantly low. It is necessary to establish methods of early diagnosis of gastric carcinomas in the cardiac region.

Methods: Twenty cases (21 lesions) of early gastric carcinomas in the cardiac region were resected between 1997 and 2001.

Minute carcinoma of the pancreas presenting as pancreatic pleural effusion.

A 70-year-old Japanese man with no history of pancreatitis visited his local practitioner, complaining of dyspnea on effort. Left massive pleural effusion was detected and he was then referred to our hospital. A plain chest film showed marked left pleural effusion.
