INTRODUCTION Ductal papillomas are rarely seen in salivary glands. Ductal papillomas are benign papillary tumors and originate from the neoplastic proliferation of any epithelium of the ductal system. Intraductal papilloma is a rare lesion and mostly arises from the major lactiferous duct (1-3). CASE REPORT A 65-year-old male patient referred to the otolaryngology department with the complaint of a mass in the right cheek for 3 years. There was no pain. Head and neck examination revealed the presence of an easily noticeable mass in both skin and mucosal surfaces of the right cheek. Bi-manual examination showed a 4x2 cm oval-shaped, firm, and mobile mass. Under general anesthesia, via a buccal mucosal incision, the tumor was removed without any complication and sent to the pathology department. Radiologic Features The patient was referred to the radiology department for magnetic resonance (MR) exam. MR exam was performed with a 1.5-T system MR scanner (Intera, Philips Medical Systems, Best, The Netherlands). Axial, coronal, and sagittal T1 TSE -T2 TSE weighted images, axial T2 weighted SPIR images, diffusionweighted series, and post-contrast series were taken. Postcontrast images were acquired after administration 0.1 mmol/ kg gadolinium diethylenetriamine pentaacetic acid. On MR imaging, a 42x28x14 mm multilobulated, T1WS isointense, T2WS hyperintense, heterogeneous subcutaneous mass adjacent to right corpus mandibula (Figure 1a-b). Diffusion was restricted, and the lesion showed homogeneous contrast enhancement on contrast series (Figure 2). There was no mandibular bony defect. The lesion was excised, and the specimen was sent for histopathological evaluation. Microscopic features (Figures 3,4): a dilated, unicystic structure was located below the mucosal surface. Cystic space was CASE REPORT Cite this article as: Yalçın Ö, Polat Y, Arslan G, Vural Ç, Kulduk G, Düşmez Apa D. Intraductal Papilloma of Buccal Mucosa Minor Salivary Gland Origin.
