case_images: On colonoscopy, an incidental 7 mm submucosal nodule was seen in the proximal rectum at 12 cm from the anal verge (Figure 1).
case_images: Rectal endoscopic ultrasound (EUS) showing a localized hypoechoic submucosal lesion with tiny hyperechoic bands without muscularis propria invasion. Muscularis mucosae (yellow arrow), submucosa (blue arrow), and muscularis propria (red arrow).

case_images: Two hemostatic clips were placed to close the mucosal defect (Figure 4).
case_images: Pathology images of the traumatic rectal neuroma. (a) Low-power view. Note the mucosa on the top (M), the muscularis mucosae (MM), and the submucosa (SM). The lesion contained in the submucosal (arrow). (b) High-power view of the neural cells in the submucosa comprised of haphazardly proliferating spindle cells.

case_images: Pathology of the specimen revealed a well-circumscribed 4 mm submucosal traumatic neuroma comprised of haphazardly proliferating spindle cells consistent with Schwann cells embedded in a fibrous stroma (Figure 5).
