Atypical presentation of a cushion sign-positive stomach gastrointestinal stromal tumor with cystic formation: A case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Gastrointestinal stromal tumors (GIST) typically appear as solid masses, and cystic formation is uncommon. Most stomach GISTs with cystic formation progress outside the gastric wall and are frequently misdiagnosed as epigastric cystic tumors derived from pancreas or liver. An asymptomatic 72-year-old male underwent esophagogastroduodenoscopy, which revealed a submucosal tumor (SMT), approximately 50 mm in diameter, at the anterior wall of the gastric angle. The SMT was very soft with positive cushion sign. Endoscopic ultrasonography and contrast-enhanced computed tomography revealed that the SMT was a cystic tumor with solid component. Laparoscopic and endoscopic cooperative surgery were performed to remove the tumor. Histopathological analysis revealed that the tumor was a GIST with cystic formation. To the best of our knowledge, this the first documented case of a cushion sign-positive stomach GIST with cystic formation, which had mainly developed inside the stomach. This case suggests that we should keep in mind the possibility of cystic formation of GIST when the tumor has a solid component, even if it appears as a cushion sign-positive SMT.
