“…Corticosteroids also inhibit the transcription of a broad spectrum of genes including those encoding monocyte or T cell‐derived cytokines and several hemopoietic growth factors 9 . Therefore, in the present case, immunosuppressive therapy may have disturbed the natural balance of growth factors and cytokines required for ulcer healing, which led to the development of a larger hyperplastic polyp than was previously reported 3 . A recent report by Amaro et al.…”

A 59-year-old man underwent endoscopic mucosal resection (EMR) for gastric adenoma. He had suffered from end-stage renal disease for several years and had received renal transplantation some 5 months before EMR. Subsequently, he took immunosuppressive agents. Follow-up gastrofiberscopy 6 months after EMR showed a sessile polyp at the resection site twice as large as the original adenoma; biopsy specimens revealed a hyperplastic nature. At the time of writing, this hyperplastic polyp has neither increased in size nor developed adenomatous or carcinomatous changes by histological examinations over the past 5 years. Therefore, this is a case of hyperplastic polyp occurring at the gastric adenoma resection site, and suggests the possible effect of immunosuppressive therapy on the post-EMR healing process and hyperplastic polyp development.

“…When an elevated lesion is encountered at the resection site, it may be assumed to be due to tumor recurrence. However, hyperplastic polyps occasionally develop at resection sites after EMR for gastric adenoma 3 …”

“…Our case occurred at the ESD resection site, and we hypothesized that it may have occurred during the healing process of an ulcer created therein. In some case reports, there are reports of hyperplastic polyps occurring at the endoscopic resection site [ 10 ]. However, GCT-ST differs macroscopically from hyperplastic polyps in its smooth surface and multinodular polypoid mass.…”

Background A giant cell tumor (GCT) is a benign neoplasm characterized by mixture of mononuclear cells and multinucleated cells. A GCT of soft tissue (GCT-ST) is developed in various extraosseous sites, but GCT-ST of the gastrointestinal tract is very rare. GCT-ST usually has a benign course, but rare cases reported malignant potential of the tumor. Therefore, complete resection is required to prevent local recurrence or distant metastasis. Case presentation A 53-year-old woman was admitted for follow-up colonoscopy who underwent the colorectal endoscopic submucosal dissection (ESD) of a laterally spreading tumor at the hepatic flexure 6 months ago. A colonoscopy showed a polypoid mass about 3.5 × 2.5 cm at the previous ESD site. As endoscopic finding showed a smooth multi-nodular tumor without submucosal invasion, we performed endoscopic mucosal resection. Based on pathological and immunohistochemical findings, the lesion was diagnosed as a GCT-ST in the colon. Follow-up colonoscopy performed 6 months later revealed no evidence of recurrence. Conclusion This is the first report of a GCT-ST identified in the colon. Although GCT-ST generally has a benign clinical course, complete resection should be performed to prevent local recurrence and metastasis.
