We report herein a case of Schwann cell hamartoma with surficial multinodular tactile corpusclelike bodies on the dorsum of the tongue in a 22-year-old female. The patient had noticed a tumorous swelling with irregular surface on the right side of tongue since her childhood. She visited our department in the hope of resolving the swelling in 2011. Subtotal resection was performed to achieve cosmetic reduction of the lesion. The surgical specimen showed proliferating Schwann cells underneath the mucosal epithelium, which were localized in the lamina propria with no copsulation. The proliferating cells showed positive immunoreactivity for S-100 and SOX10. There was no cellular nor nuclear atypism. These findings corresponded to Schwann cell hamartoma. There has been no growth of the lesion in the seven years after operation.
