瘤细胞瘤(oncocytoma)是一种来源于上皮的不常见的肿瘤,约占唾液腺肿瘤的1％以下,此肿瘤可发生于身体各不同部位,但多数发生于腮腺,少数发生于颌下腺,小的唾液腺或粘液腺,亦可发生于腭部、扁桃体窝、喉部、鼻腔并可扩展到鼻窦和泪腺。本文作者报告一例上颌窦瘤细胞瘤,并复习世界文献,尚未见到类似报告。病例报告摘要: 病者男性,64岁,左侧颊部和上牙感觉异常、不适二年,近二月来,伴有疼痛。临床检查,头颈部未见异常。X线常规照像,左侧上颌窦显影混浊,未见骨质破坏,诊断鼻窦炎,应用抗菌素治疗,症状未见减轻,并持续存在,遂行左侧上颌窦Caldwell-Luc探查术和造孔,术中 Oncocytoma is an uncommon tumor that originates from the epithelium and accounts for about 1% of salivary gland tumors. This tumor can occur in various parts of the body, but most occur in the parotid gland, and a few occur in the submandibular gland. Small Salivary glands or mucous glands can also occur in the ankle, tonsil fossa, larynx, nasal cavity and can be extended to the sinus and lacrimal gland. The authors report one case of a maxillary sinusoidal cell tumor and review the world literature. No similar report has been reported. Case Report Abstract: The patient is male, 64 years old. His left cheek and upper teeth are abnormal and discomfort for two years, and in the past two months, accompanied by pain. Clinical examination showed no abnormalities in the head and neck.
