Mucosal Schwann Cell Hamartoma Mimicking a Colon Polyp
A rectal polyp is found during a routine colonoscopy of a 34-year-old male. He has no known significant family history of inherited disorder. Endoscopic findings reveal a 5-mm JNET 2A polyp in the rectum which is removed via forceps polypectomy. The microscopic examination shows a polypoid colonic...

A rectal polyp is found during a routine colonoscopy of a 34-year-old male. He has no known significant family history of inherited disorder. Endoscopic findings reveal a 5-mm JNET 2A polyp in the rectum which is removed via forceps polypectomy. The microscopic examination shows a polypoid colonic mucosa with fairly circumscribed proliferation of low-grade spindle cells in the lamina propria, separating the crypts. The individual spindle cells are uniform in size with abundant eosinophilic cytoplasm. No mitotic figures, nuclear atypia, pleomorphism and necrosis are noted. Likewise, the crypts do not exhibit serrated architecture.
