AI Article Synopsis
- Villous tumors of the stomach are rare, with only about 100 cases documented, and they have a high risk of malignant transformation (up to 72%).
- These tumors often occur multiple times and can be associated with other gastrointestinal cancers, including an independent gastric carcinoma in 30% of cases.
- A case study highlights a 64-year-old man with significant symptoms, where imaging and biopsy confirmed a gastric villous tumor that had undergone carcinomatous changes.
Article Abstract
Villous tumors of the stomach are somewhat rare with approximately 100 cases only reported in the literatures and have tendency to undergo malignant transformation as high as 72%. They are frequently multiple and associated with other gastrointestinal neoplasm. Thirty percent of them are associated with an independent gastric carcinoma. Gastric villous tumor has certain radiologic characteristics that may permit a preoperative diagnosis and also some distinctive clinicopathologic features which make early diagnosis and proper treatment possible. We experienced a 64-year-old man who complained of prolonged general weakness, weight loss for several months and left upper quadrant pain for four days. Esophagogastroduodenoscopy and barium study of upper gastrointestinal tract demonstrated typical, irregular, frond-like surfaced villous tumor occupying nearly whole gastric lumen and located eccentrically along the lesser curvature side. Endoscopic biopsy of the tumor revealed a gastric villous tumor with carcinomatous change.

Background: McKittrick-Wheelock syndrome is an uncommon and severe disorder caused by large hypersecretory tumors located in the distal colorectal area. Excessive secretion from adenomas is an unusual clinical manifestation that leads to severe electrolyte and fluid depletion, subsequently resulting in kidney injury. Successful treatment relies on quick and cooperative decision-making for timely intervention.

Introduction: Immune checkpoint inhibitors (ICI) are used to treat various malignancies. They block the inhibitory signals of tumor cells and enhance the inflammatory cascade, which results in tumor killing. However, this can lead to unchecked inflammation throughout the body, leading to various adverse effects.

Article Synopsis
- - During pregnancy and lactation, mammals experience significant changes in their intestinal epithelium, leading to an increase in intestinal surface area through the expansion of villi.
- - The RANK-RANKL molecular pathway is crucial for this process, protecting gut cells from death and promoting intestinal stem cell activity, which results in villous elongation.
- - Mice lacking RANK in their intestinal epithelium have offspring that are heavier and more prone to glucose intolerance, highlighting the importance of RANK-RANKL in both immediate and long-term health outcomes for offspring.
