Synchronous gastric leiomyoma and intramuscular abdominal wall granular cell tumor with similar imaging features: A case report
Conclusion Laparoscopic-endoscopic cooperative surgery can be an effective minimally invasive approach to resect some lesions. This is first report of the patient with a synchronous gastric leiomyoma and an intramuscular granular cell tumor in the abdominal wall.
To identify significant clinical and CT features for the differentiation of gastrointestinal stromal tumors (GISTs) from leiomyomas in the esophagogastric junction (EGJ). One hundred thirty six patients with pathologically proven GISTs (n = 87) and leiomyomas (n = 49) in the EGJ were enrolled. And preoperative CT images were available in 73 GISTs cases and 34 leiomyoma cases. Two radiologists reviewed the CT images by consensus with regard to tumor size, shape, growth pattern, surface, enhancement pattern, enhancement degree, attention at each phasic image and the presence of surface ulcer, calcification, and intr...
Conclusions: Clear exposure of gastric SETs during MCB may improve the diagnostic rate of such examinations. PMID: 32053861 [PubMed - as supplied by publisher]

CT imaging fe...
ConclusionsER is effective and safe for patients with GS with favorable long-term outcomes.
ConclusionTotal laparoscopic surgery was effective for colonic leiomyoma with an abdominal mesh to avoid mesh-related complications.
Conclusions: RLSD precisely locates gastric benign tumors during laparoscopic-endoscopic rendezvous procedures.
ConclusionsThis pilot study showed the potential of radiomics to distinguish GIST from other GI tumors, but no potential in predicting c-KIT mutational status and mitotic index of GISTs. Further optimization and validation of the radiomics model is required to incorporate radiomics in the diagnostic routine of GISTs.AcknowledgementM.J. Timbergen and M.P.A.

ConclusionsAlthough a majority of the subepithelial lesions in the cardia of the stomach are benign, 20% of the cases diagnosed with GIST have a high malignant potential. Preoperative EUS-FNB might be a useful tool for decision-making regarding the ultimate management and outcomes of these lesions.
Conclusions: : APCT showed a lower overall accuracy than EUS; however, APCT remains a useful modality for malignant/potentially malignant gastric SETs. PMID: 31311912 [PubMed - as supplied by publisher]
Esophageal submucosal tumors (SMTs) are tissue protuberances covered with normal mucosa, usually without clinical symptoms. In esophagus, leiomyomas and gastrointestinal stromal tumors (GISTs) are two common SMTs and originate from the muscularis propria (MP) layer. The most are benign, but 10.8% leiomyomas might turn into leiomyosarcomas. GISTs are reported to be potentially malignant, especially with the large size or irregular boundary. Submucosal tunneling endoscopic resection (STER) and endoscopic submucosal excavation (ESE) are recently introduced to remove submucosal tumors (SMTs) originating from the muscularis propria (MP) layer.
