十二指腸に濾胞性リンパ腫，リンパ濾胞過形成，リンパ管腫およびリンパ管拡張を合併した1 例

Title Alternative	Four types of duodenal white lesions (follicular lymphoma, lymphoid hyperplasia, lymphangiectasia, and lymphangioma) : A case report
FullText URL	133_175.pdf
Author	Iwamuro, Masaya\| Tanaka, Takehiro\| Okada, Hiroyuki\|
Abstract	A 70-year-old Japanese man underwent esophagogastroduodenoscopy that revealed multiple whitish duodenal granules. The histopathological analysis of the biopsied specimen led to the diagnosis of duodenal-type follicular lymphoma. The lesion showed spontaneous improvement ; however, 14 months later a few small whitish granules were observed by esophagogastroduodenoscopy. Observation under magnification revealed slightly elevated opaque white spots and whitish granular protrusions of roughly the same size that were uniformly distributed in the duodenal bulb. The duodenal bulb lesions were histopathologically diagnosed as lymphoid hyperplasia. The patient also exhibited lymphangiectasia (which presented as scattered white spots) and lymphangioma (which presented as a soft submucosal tumor with white spots on the surface) in the second portion of the duodenum. This patient presented with four white lesions in the duodenum : duodenal-type follicular lymphoma, lymphoid hyperplasia, lymphangiectasia, and lymphangioma. Careful endoscopic evaluation enabled a prompt diagnosis in this case.

Reality of Gastric Cancer in Young Patients: The Importance and Difficulty of the Early Diagnosis, Prevention and Treatment

FullText URL	74_6_461.pdf
Author	Kono, Yoshiyasu\| Kanzaki, Hiromitsu\| Iwamuro, Masaya\| Kawano, Seiji\| Kawahara, Yoshiro\| Okada, Hiroyuki\|
Abstract	Gastric cancer usually arises in middle-aged to older patients, and is rarely found in younger patients. The clin-ical characteristics, etiology, prognosis, preventive methods and treatment of gastric cancer in young patients have not been fully investigated because of its low prevalence. In this review, we discuss the current under-standing and clinical problems associated with gastric cancer in young patients. Helicobacter pylori (H. pylori), which is a major cause of gastric cancer, especially in older populations, is closely associated with gastric cancer in young patients as well as in older patients. Gastric cancer in young patients tends to be diagnosed at an advanced stage with alarm symptoms. However, young patients with advanced gastric cancer tend to have a favorable general condition and organ function, so they can tolerate intensive systematic chemotherapy. Unfortunately, the prognosis of gastric cancer in young patients with an advanced stage is not favorable. We should not take this rare disease lightly, given its poor prognosis if patients are diagnosed at an unresectable stage. The evaluation of the H. pylori infection status and performance of H. pylori eradication therapy to prevent gastric cancer in young patients as well as the development of more intensive chemotherapy regimens for unre-sectable gastric cancer in young patients are warranted.
