Extraoral type of intraductal papilloma in sublingual gland: A case report

Abstract

INTRODUCTION: It is rare for intraductal papilloma (IDP), a benign papillary tumor, to occur in the sublingual gland (SLG). CASE SUMMARY: A 55-year-old man incidentally found a painless mass in his left submandibular region (SMR). He had a history of two surgeries for bilateral SLG cyst. Contrast enhanced ultrasound (CEUS) and magnetic resonance imaging (MRI) were performed. The patient received trans-cervical excision of left residual SLG in combination with excision of left submandibular gland (SMG). The postoperative course was uneventful and no signs of recurrence during 5 months of follow-up. DISCUSSION: For a SMR mass, extraoral type of IDP in SLG should be considered in the differential diagnosis.
