Massive Gastric Juvenile Polyposis: A Clinicopathologic Study Using SMAD4 Immunohistochemistry.

Objectives: Juvenile polyps involving the stomach are uncommon. Massive gastric juvenile polyposis is even rarer.

Methods: We describe the clinicopathologic features of nine cases of massive gastric juvenile polyposis.

Gastric hyperplastic polyps in post transplant patients: a clinicopathologic study.

Gastric hyperplastic polyps in organ transplant recipients have been recently described; however, the clinical significance of hyperplastic polyps in this setting remains unclear. The aim of this study is to further characterize the clinical presentation and histopathology of gastric hyperplastic polyps in organ transplant recipients as compared to hyperplastic polyps in non-transplant individuals. All gastric hyperplastic polyps diagnosed in our institute from 1999 to 2005 were retrieved.
