Abstract
BACKGROUND
Submucosal tumor (SMT)-like early-stage gastric cancer (GC) has rarely been reported. It is difficult to consider the possibility of GC and differentiate it from other submucosal lesions.
CASE SUMMARY
We present the case of a 50-year-old male patient with a 1.6 cm SMT-like flat elevated lesion covered by congested mucosa on the gastric angle. Magnifying endoscopy with narrow-band imaging, endoscopic biopsy, endoscopic ultrasound, and computed tomography were performed for diagnosis. Endoscopic submucosal dissection and gastrectomy with lymph node dissection were performed. The post-resection pathological analysis led to a final diagnosis of GC (Bormann type I, T1bN2M0).
CONCLUSION
GC should be considered when detecting an SMT-like lesion in the stomach.
Core tip: Gastric adenocarcinoma showing features of a submucosal tumor is unusual. Preoperative diagnosis is difficult due to the generally deep location of the tumor and non-specific and overlapping features on imaging studies. In this case, esophagogastroduodenoscopy revealed a 1.6 cm type 0-Is lesion covered by congested mucosa on the gastric angle. Endoscopic ultrasound and computed tomography reveal no swollen lymph nodes and the usual biopsy cannot give a definite diagnosis. After endoscopic submucosal dissection and gastrectomy with lymph node dissection, this patient was diagnosed with GC (Bormann type I, T1bN2M0).
