Gastrointestinal Tactile Corpuscle-Like Bodies: Report of Two Cases and Review of the Literature.

Gastrointestinal tactile corpuscle-like bodies are a rare, incidental, entirely benign finding. It is mainly reported in the colorectum and esophagus/gastro-esophageal junction. Rare cases have been documented in the stomach. Here, we present two cases of gastric and colonic tactile corpuscle-like bodies of a 38-year-old female and a 55-year-old male, respectively. Endoscopically, the colonic lesion was resected as an adenomatous polyp, while the gastric biopsies were taken to rule out Helicobacter pylori (H. pylori) gastritis. Microscopically, both specimens revealed the same histopathologic aspects of eosinophilic fibrillary material with round to oval cells and peripherally placed nuclei. Immunohistochemically, these lesions were positive for anti-S100, confirming the diagnosis of tactile corpuscle-like bodies. A thorough literature review is provided.
