. 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. . We report a case of unilateral submandibular gland oncocytoma in a 63-year-old Caucasian man. . 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. . 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.
下颌下腺嗜酸性细胞瘤是罕见的良性涎腺肿瘤。它们通常见于50至70岁的白种人患者，无性别差异。由于头颈部肿瘤在组织学和临床特征上存在重叠，它们常被误诊。我们报告一例63岁白种男性单侧下颌下腺嗜酸性细胞瘤病例。该患者接受了单侧下颌下腺切除术及肿瘤标本的组织病理学分析。在术后2周和1年的随访中，未发现复发。下颌下腺嗜酸性细胞瘤最好通过术前细针穿刺抽吸活检（FNA）和CT成像进行诊断，在细胞学和组织学上有独特表现。CT检查后行细针穿刺抽吸细胞学检查将是首选的诊断方法。由于其恶变和复发率低，最佳治疗方法是局部切除并根据需要进行随访。
