Published: June 2016

We report the case of a 55-year-old woman with a tumor in the greater curvature of the upper gastric body. The tumor was incidentally found on an upper gastrointestinal X-ray series performed during a routine medical examination. Whereas endoscopy revealed a gastric submucosal tumor (SMT), endoscopic ultrasonography demonstrated a heterogeneous tumor with small, cystic, hypoechoic spots originating from the second layer. The patient was clinically asymptomatic, with no contributory family history or abnormal laboratory data. The results of a physical examination, abdominal computed tomography, and plain chest radiography were all unremarkable. Although the endoscopic tumor type was determined to be SMT, the tumor was successfully resected by endoscopic submucosal dissection (ESD) and subsequently diagnosed as a gastric hamartomatous inverted polyp (GHIP). The findings of the present case highlight the importance of considering GHIP as a diagnosis and indicate the utility of en bloc resection of GHIP with ESD.

Peutz-Jeghar syndrome (PJS) is an inherited condition that puts people at an increased risk for developing hamarotmatous polyps in the digestive tract as well as cancers of the breast, colon, rectum, pancreas, stomach, testicles, ovaries, lung and cervix. With typical presentation, majority cases of PJS can be diagnosed in childhood. PJS is inherited by mutation in the STK II gene, also known as LKB1 gene.

Multigene panel testing has allowed for the detection of a growing number of inherited pathogenic/likely pathogenic variants in people at high risk of cancer, including endometrial cancer (EC). Hereditary syndromes associated with EC include Lynch syndrome, PTEN hamartoma tumor syndrome, and Peutz-Jeghers syndrome. This manuscript provides the latest recommendations from the NCCN Guidelines for Genetic/Familial High-Risk Assessment: Colorectal, Endometrial, and Gastric on the screening and management of EC in patients at high risk for these syndromes, as well as the advantages and limitations of multigene panel testing.

Article Synopsis
  • A 58-year-old woman with a stomach lesion underwent tests revealing a lobulated mass, leading to a fine needle biopsy that suggested an inflammatory fibroid polyp.
  • The patient had laparoscopic surgery, and the postoperative analysis identified the lesion as a gastric hamartomatous inverted polyp (GHIP) due to its specific growth patterns and tissue characteristics.
  • The study emphasizes the importance of distinguishing between fibrous tumors and GHIPs based on ultrasound echo patterns, which can aid in accurate diagnosis.

Article Synopsis
  • Brunner's gland hamartoma (BGH) is a benign tumor found in the duodenal bulb, often asymptomatic but can sometimes lead to anemia.
  • A 76-year-old male patient with prostate cancer was monitored for anemia over 10 years, during which a polyp in the duodenum was noted and assessed through multiple endoscopies.
  • Eventually, due to significant growth of the polyp and worsening anemia, an endoscopic polypectomy was performed, confirming the tumor as BGH.
