Accessory parotid gland (APG) is seen in around 21%-56% of individuals. Tumors of accessory parotid are uncommon with an incidence rate of 1%-8% of all parotid tumors. Ductal carcinoma of APG is rare, so no reported incidence was seen in the literature. However, salivary gland ductal carcinoma is reported to be 1% of all salivary gland neoplasms. We report here a case of salivary duct carcinoma of APG. Clinical presentation, investigation, and management are discussed. A 69-year-old female presented with a history of the left cheek progressive swelling of 6 years' duration. Computed tomography and magnetic resonance imaging showed heterogeneous lobulated ill-defined mass over the left masseter. Fine needle aspiration was inconclusive. Excision of the mass showed salivary duct carcinoma. Ductal carcinoma of APG is an aggressive tumor which needs to be managed aggressively. Standard parotidectomy incision approach seems to be a safe and efficient way of management.
约21%-56%的人存在副腮腺（APG）。副腮腺肿瘤并不常见，占所有腮腺肿瘤的发病率为1%-8%。APG的导管癌罕见，文献中未见报道的发病率。然而，据报道涎腺导管癌占所有涎腺肿瘤的1%。我们在此报告一例APG涎腺导管癌病例。讨论了临床表现、检查及治疗。一名69岁女性，有左侧面颊进行性肿胀6年病史。计算机断层扫描和磁共振成像显示左侧咬肌上方有不均匀分叶状边界不清的肿块。细针穿刺结果不明确。肿块切除显示为涎腺导管癌。APG的导管癌是一种侵袭性肿瘤，需要积极治疗。标准腮腺切除术切口入路似乎是一种安全有效的治疗方法。
