Abstract：
Salivary gland neoplasms account for 3% of all head and neck tumours. Pleomorphic adenoma (PA) is the most common salivary gland tumour that mainly occurs in the parotid gland, followed by minor salivary glands of the oral cavity, however, the occurrence of PA inside the jaw bones is exceedingly rare and very few cases have been reported in the literature. Inside jaw bones these lesions tend to imitate large osteolytic lesions encompass a diagnostic challenge. An exhaustive review of the literature revealed only 10 cases of central pleomorphic adenoma. We present a rare case of primary PA that occurred inside the mandible and was provisionally diagnosed as ameloblastoma.
摘要：
唾液腺肿瘤占所有头颈部肿瘤的3%。多形性腺瘤（PA）是最常见的唾液腺肿瘤，主要发生在腮腺，其次是口腔的小唾液腺，然而,下颌骨内PA的发生极为罕见，文献中报道的病例很少。在颌骨内部，这些病变倾向于模仿大型溶骨性病变，这包括诊断挑战。详尽的文献回顾显示仅10例中央多形性腺瘤。我们介绍了一例罕见的原发性PA病例，该病例发生在下颌骨内部，并被暂时诊断为成釉细胞瘤。
