Solitary gastric juvenile polyp in an adult patient: A rare case report and review of the literature

Juvenile polyps are benign hamartomatous lesions usually seen in children, most often in the colorectal region. Solitary gastric juvenile polyps in adults without features of polyposis syndromes are exceedingly rare, with fewer than five cases reported in the literature. We describe a 31-year-old male presenting with weight loss and intermittent painless rectal bleeding. Upper endoscopy revealed a solitary pedunculated polyp in the gastric antrum, which was removed via endoscopic mucosal resection. Colonoscopy showed internal hemorrhoids and a solitary rectal ulcer, which were likely the source of bleeding, while small bowel imaging was unremarkable. Histopathology confirmed a juvenile polyp. This case emphasizes the importance of recognizing this rare entity and the role of endoscopy in diagnosis and management.
