中文摘要 | 周邊型齒釉細胞瘤為相為少見的骨外齒源性腫瘤, 外國文獻中迄今只有 50 餘例 的報導。好發位置大多在牙床附近的軟組織。周邊型齒釉細胞瘤的臨床表現和中央型(骨內 發生)不同,比較少侵犯周圍組織,所以經常以完整的外生性硬塊出現。組織學上,兩者類 似,大多呈良性。不過,仍有惡性變化或轉移的可能。治療上以外科方式完整切除主。局部 復發或轉移很少發生。本病例報告的腫瘤發生於罕見的左上頜竇,臨床上以流鼻血來表現, 腫瘤經左側鼻切開術及內側上頜摘除術切除,病理切片證實為周邊型齒釉細胞瘤,腫瘤週圍 骨質仍然完整。病患術後情況良好,門診追蹤迄今已 19 個月,未發現局部復發或遠處轉移 。 |
英文摘要 | Peripheral ameloblastoma is a rare extraosseous odontogenic tumor arising from the tooth-bearing soft tissue of the mandible and maxilla. Fifty- three cases have been recorded so far. Their clinical pictures do not manifest as aggressive and invasive as the central one. Most of them are usually firm, sessile and exophytic. Peripheral ameloblastoma has the similar histologic characteristics of their counter part, mostly benign. Malignant change or distal metastasis is rare. Surgical excision with free safety margin is adequate for the treatment. We reported a rare case of left maxillary sinus tumor with the initial presention of epistaxis. The tumor was removed by left lateral rhinotomy and medial maxillectomy. Microscopic examination revealed peripheral ameloblastoma. No bony invasion was found. The post-operative coure was uneventful. No regional recurrence or distal metastasis has been found for 19 months. |
