颌下腺和咽旁间隙同时出现多形腺瘤是稀有的。我们报道了一例65岁男性在西北总医院耳鼻喉门诊部就诊，患有颌下腺和咽旁间隙的多形腺瘤。患者来诊时左侧颌下腺瘤并排外口腔检查发现左侧腭扁桃体向内压迫。颈部CT检查显示左侧咽旁间隙完全分开的肿块，针吸细胞检查表明颌下腺瘤有黏液表皮样癌的病理表现。首先切除了浅表颌下腺瘤，接着经口内手术进行咽旁间隙肿瘤切除。病理学检查证实两个肿瘤都是多形腺瘤。我们需要提高对同步唾液腺肿瘤的认识，这是一种罕见的情况，需要进行全面的手术切除和适当的管理。

Synchronous pleomorphic adenoma in the parotid gland and parapharyngeal space are rare. We report a case of simultaneous pleomorphic adenoma in parotid gland and parapharyngeal space in a 65-year-old male presenting to the ENT outpatient department at Northwest General Hospital, Peshawar. The patient presented with a left parotid lump, intra oral examination of which revealed the left palatine tonsil to have been pushed medially. CT of the neck showed a completely separate lump in the left parapharyngeal space, and FNAC of the parotid lump was suggestive of mucoepidermoid carcinoma. The superficial parotid lump was excised first, and the parapharyngeal growth was accessed intraorally and excised. Histopathology revealed both the growths to be pleomorphic adenomas. It is important to raise awareness of synchronous salivary gland tumours, which are a rare occurrence, to highlight its optimal investigation to ensure complete surgical excision, and appropriate management.
