下鼻甲多形性腺瘤1例

One case of pleomorphic adenoma originates from inferior nasal turbinate

患者,女,59岁,以右侧鼻腔阻塞3年加重1年为主诉就诊于我院。患者3年前无明显诱因出现右侧鼻腔持续性阻塞,伴右侧鼻腔间断性黄浓涕、间断性头闷胀感、右侧嗅觉障碍,无右侧鼻腔反复出血、鼻部疼痛、头痛等症状。1年前患者感右侧鼻阻渐进性加重。入院检查：外鼻无畸形,鼻中隔未见明显偏曲,右侧下鼻甲肥大完全阻塞前鼻孔,使用麻黄素收缩下鼻甲后未见明显缩小;左侧鼻腔内、鼻腔后部及鼻咽部未见明显异常。入院后鼻窦冠状位CT（图1）示：右侧鼻腔息肉可能;右侧鼻窦、双侧后鼻孔区正常,CT未见鼻腔明显骨质浸润。

Pleomorphic adenoma（PA）is the most common benign tumor of the salivary glands.Originating from the nasal cavity is very rare.This paper reports one case of pleomorphic adenoma of the inferior nasal turbinate to analyze the clinic characteristic of this disease.Although these tumors are rarely seen in everyday practice,one should consider this possibility as an uncommon aetiology when confronted with an intranasal mass.
