Tongue squamous cell carcinoma metastasis to percutaneous endoscopic gastrostomy site: A case report of an unusual cause of gastrointestinal bleeding.

Percutaneous endoscopic gastrostomy tubes are often placed in patients with head and neck malignancy for long-term nutritional support. Though rare, head and neck squamous cell carcinoma can metastasize to the percutaneous endoscopic gastrostomy tube site and may initially present as a developing mass or as bleeding at the percutaneous endoscopic gastrostomy site. Patients with head and neck squamous cell carcinoma should be evaluated diligently before and after percutaneous endoscopic gastrostomy placement in order to avoid this rare but life-threatening complication. We present a case of tongue squamous cell carcinoma that metastasized to the percutaneous endoscopic gastrostomy tube site causing gastrointestinal bleeding.

McKittrick-Wheelock syndrome: A rare cause of chronic diarrhea treated with endoscopic polypectomy.

Chronic diarrhea is a commonly encountered complaint and a principal cause of health care utilization worldwide. Although there are various etiologies of chronic diarrhea, McKittrick-Wheelock syndrome is a rare syndrome defined as a large villous adenoma with secretory diarrhea causing severe fluid imbalances. We report a case of a patient with McKittrick-Wheelock syndrome who was successfully treated with endoscopic resection. Our case aims to add information to the current literature supporting the endoscopic management of McKittrick-Wheelock syndrome.
