The accessory submandibular gland is a rare anatomic variant and the incidence of pathology reported within an accessory submandibular gland is even rarer. This report describes the case of a 22-year-old woman who presented with a slowly enlarging mass in the submandibular triangle, which on ultrasound examination suggested that it was close to, but not arising from, the submandibular gland. Fine-needle aspiration cytology was consistent with a pleomorphic adenoma. At surgery, the tumor was found to be entirely separate from the submandibular gland. This case presents an extremely rare occurrence of an accessory submandibular gland and, to the authors' knowledge, is the first report of a pleomorphic adenoma occurring within an accessory submandibular gland.
副下颌下腺是一种罕见的解剖变异，而报道的副下颌下腺内发生病变的情况更为罕见。本报告描述了一名22岁女性的病例，该患者下颌下三角区有一缓慢增大的肿块，超声检查显示该肿块靠近下颌下腺，但并非起源于下颌下腺。细针穿刺细胞学检查结果符合多形性腺瘤。手术中发现肿瘤与下颌下腺完全分离。该病例呈现了极为罕见的副下颌下腺情况，据作者所知，这是首例关于副下颌下腺内发生多形性腺瘤的报告。
