Intraductal papilloma is a rare benign epithelial neoplasm of the salivary duct system, characterized by papillary proliferation of ductal epithelium into a cystic lumen. It predominantly occurs in minor salivary glands, particularly in the lips and buccal mucosa, and is rarely found in the mandibular region. We report a case of intraductal papilloma in the left retromolar trigone of a 46-year-old woman. Clinically, the lesion presented as a painless, well-circumscribed bluish submucosal mass. Radiographic findings were nonspecific, and a provisional diagnosis of hemangioma was made. The lesion was surgically excised under general anesthesia. Histopathological examination revealed a cystic cavity lined by cuboidal to columnar epithelial cells with intraluminal papillary projections, consistent with intraductal papilloma. Scattered mucous-producing cells were also noted. No evidence of recurrence was noted at the 24-month follow-up. This case highlights the importance of histopathological confirmation in diagnosing intraoral submucosal lesions.
