title: Oncocytoma of the Submandibular Gland: Diagnosis and Treatment Based on Clinicopathology.
abstract: Background. Submandibular oncocytomas are rare benign salivary gland neoplasms. They are typically found in Caucasian patients aged 50-70 years with no gender preference. Due to the overlapping histological and clinical features of head and neck tumors, they are often misdiagnosed.Methods. We report a case of unilateral submandibular gland oncocytoma in a 63-year-old Caucasian man.Results. The patient underwent unilateral submandibular gland resection and histopathologic analysis of the tumor specimen. On follow-up at 2 weeks and 1 year, no recurrence was identified.Conclusion. Submandibular oncocytomas are best diagnosed with preoperative FNA and CT imaging and have distinctive findings on cytology and histology. CT followed by fine-needle aspiration cytology would be the preferred diagnostic modalities. Due to its low rate of malignant transformation and recurrence, the best treatment is local resection with follow-up as necessary.
