Two hyperplastic esophagogastric polyps in a child with neurofibromatosis type 1 (NF-1).
Hyperplastic esophagogastric polyps usually occur in the distal esophagus or gastroesophageal junction and have been associated with damage to the esophageal mucosa. Histologically these polyps show hyperplastic gastric foveolar and/or squamous epithelium with inflamed stroma. Reports of esophagogastric polyps in the pediatric population are rare. Most of these reports only describe chronic inflammation within the lamina propria of the polyp, with only rare reports specifying the presence of epithelial hyperplasia. There have been 2 previous cases of hyperplastic esophagogastric polyps occurring in the context of neurofibromatosis type 1 (NF-1) in a single article. Here we report a 3rd case of hyperplastic esophagogastric polyps occurring in an 11-year-old male with NF-1. This case is unique in that there were 2 polyps in the same patient and in that the polyps showed hyperplastic gastric peptic glands in addition to foveolar-type and focal squamous epithelium. The case is discussed and literature reviewed.
