源自倒生性乳頭狀瘤之上頜竇鱗狀細胞癌-病例報告

Squamous Cell Carcinomas of the Maxillary Sinus Arising from Inverted Papilloma - Case Report

摘要


鼻腔或鼻竇之倒生性乳頭狀瘤是一種發生於外胚層Schneider氏黏膜的良性腫瘤。由於它在組織學上的表現是以增生的上皮向下侵入結締組織的基質,形成倒生的現象,因而得名。自1854年Ward及1855年Billroth首次描述及提出報告之後,這種具有局部侵犯性,且合併高復發機率及惡性變化的罕見腫瘤,一直是學者們興趣討論的對象。本院在1993年6月經歷一名由倒生性乳頭狀瘤轉變成為上頜竇鱗狀細胞癌之病例,經由病理組織切片,可看到由乳頭狀瘤轉變為鱗狀細胞癌的轉變區而予以證實,特提出報告供讀者參考。

Inverted papillomas of the nose and paranasal sinuses are found to be associated with squamous cell carcinomas in a small percentage of cases. In June 1993, we had an unusual experience in an old male who presented with the symptoms of epistaxis and a palpale mass over the right cheek for 6 months. CT and MRI revealed an expansive mass completely filling the right maxillary sinus with mild destruction of the lateral posterior wall and anterior wall. The patient then received subtotal maxillectomy and ethmoidectomy. The histopathological diagnosis was proved as squamous cell carcinoma arising from inverted squamous papilloma. The terminology, clinical presentation, treatment and outcome of inverted papillomas and squamous cell carcinomas in association with inverted papillomas were discussed.
