[A case of XXXX with rapid growth in a short term].

@entity1 @entity6552 @entity5 @entity1066 @entity418 @entity674 @entity356
A 75-year-old @entity1 was admitted to our hospital with massive @entity6552 . Upper gastrointestinal endoscopy revealed a submucosal @entity356 with @entity1066 , about 30 mm in diameter, in the anterior wall of the @entity418 . Pathological findings of biopsy specimens showed a @entity674 ( @entity674 ) of the stomach. Abdominal computed tomography (CT) showed an extramural low density mass, measuring 27 mm, in the @entity418 . From these findings, we thought we should be performing a wedge resection of the stomach for this @entity5 . After one month from the first examination, preoperative upper gastrointestinal endoscopy revealed a growth of the @entity5 . Abdominal CT also showed an obvious growth of the @entity5 , measuring 50 mm. Thus, laparoscopy-assisted proximal gastrectomy was performed, because the @entity5 was close to the @entity418 . Postoperative diagnosis of the @entity5 was pathologically confirmed to be a @entity674 with a high malignant potential. The case report of @entity674 that shows rapid growth for a short term is rare. We herein describe a case of @entity674 with rapid growth during one month before the operation.
