鼻腔及鼻竇之倒生性乳頭狀瘤-兩例報告

Inverted Papillomas of the Nasal Cavity and Paranasal Sinuses - Report of Two Cases

摘要


倒生性乳頭狀瘤(inverted papilloma)是一種較罕見的腫瘤,它的特點在於1.復發率高,2.局部侵犯性,3.伴隨惡性腫瘤,4.多發的傾向。 臺北醫學院附設醫院耳鼻喉科自12年來經歷的14個鼻腔或鼻竇內倒生性乳頭狀瘤的病中選取兩例提出報告。其中1例伴隨類上皮癌(epidermoid carcinoma),於術後接受放射線治療。另1例鼻腔及鼻竇內倒生性乳頭狀瘤侵犯硬腦膜及右側眼眶內上壁,並發現1顱內囊腫,內含氣體液體界面(air-fluid level)。經會診神經外科醫師後,聯手施行右側額部顱骨切開術(frontal craniotomy),清除腫瘤後情況穩定,至今無復發現象,特提出報告。

Inverted papilloma is a relatively uncommon lesion of the nasal cavity and paranasal sinuses. It is characterized by a high recurrence rate, local invasiveness, association with malignancy, and tendency to be multicentricity. We hereby reported two cases from 14 cases of inverted papilloma of the nasal cavity and paranasal sinuses encountered in TMCH during 1980-1992 perid. One was associated with epidermoid carcinoma and received radiotherapy after surgery. The other was diagnosed as inverted papilloma of the right nasal cavity and paranasal sinuses with invasion of the dura and medio-superior wall of the right orbit. Moreover, a well-defined space-occupying lesion with air-fluid level was noted in the right frontal lobe. The tumor was removed via right frontal craniotomy by the cooperation of ENT doctor and neurosurgeon. The post-operative course was uneventful. There has been no evidence of recurrence until now.
