World literature suggests parapharyngeal space lesions account for only 0.5% head and neck tumours and the majority of the minor salivary gland tumours are malignant. The parapharyngeal space is very rare site for this tumour.
Two cases of primary pleomorphic adenomas arising de novo from minor salivary glands in the para pharyngeal space are reported. Review of literature, clinical features, pathology, radiological findings and treatment of these tumours are discussed.
Pleomorphic adenoma arising de novo in the parapharyngeal space is of rare occurrence. High index of suspicion and an adequate clearance of the tumour with a cuff of surrounding dispensable normal tissues is the key to successful treatment of such tumours.
世界文献表明咽旁间隙病变仅占头颈部肿瘤的 0.5%，且大多数小唾液腺肿瘤为恶性。咽旁间隙是这种肿瘤非常罕见的部位。
报告了 2 例原发于咽旁间隙小唾液腺的多形性腺瘤。讨论了这些肿瘤的文献复习、临床特征、病理、影像学发现和治疗。
原发于咽旁间隙的多形性腺瘤较为罕见。高度怀疑和充分清除肿瘤，并保留周围可牺牲的正常组织袖套是成功治疗此类肿瘤的关键。
