Oncocytomas are rare tumors; they occur most often in the parotid gland and here behave in a benign fashion. Few of these tumours have been described arising from tissues of the upper jaw. The reviews of the literature in these cases often appear incomplete. It has been suggested that outside the major salivary glands oncocytomas should be considered to be low-grade adenocarcinomas.
We present a case of a 78-year-old woman with a frankly malignant oncocytoma of the lateral nasal wall, treated with radical local excision. A search of the world literature was undertaken and a review conducted.
We found a total of 19 cases affecting the upper jaw, in a wide age distribution, 10 male and 9 female. Thirteen cases were malignant, 3 with metastases.
When affecting the upper jaw, these tumors must be considered malignant. Radical surgical excision is the treatment most often employed.
嗜酸细胞瘤是罕见肿瘤；最常发生于腮腺，且在腮腺表现为良性。仅有少数此类肿瘤被描述为起源于上颌组织。这些病例的文献综述往往不完整。有人提出，在大唾液腺之外，嗜酸细胞瘤应被视为低级别腺癌。
我们报告一例78岁女性患者，其外侧鼻壁发生了明确的恶性嗜酸细胞瘤，接受了根治性局部切除术。我们检索了世界文献并进行了综述。
我们共发现19例累及上颌的病例，年龄分布广泛，男性10例，女性9例。13例为恶性，3例有转移。
当累及上颌时，这些肿瘤必须被视为恶性。根治性手术切除是最常采用的治疗方法。
