摘要

源性纖維瘤為一罕見良性顎骨腫瘤，僅占顎骨齒源性腫瘤0.1%。齒源性纖維瘤生長緩慢，多造成顎骨無痛性腫大。放射線檢查多呈現單囊性放射線穿透影像，某些案例會導致牙根吸收或移位。齒源性纖維瘤對手術刮除反應良好，惡性轉變及復發之比率極低。本病例報告一53歲女性於下顎右側第一大臼齒區發現一無痛腫脹區域數月，門診檢查口內上皮完整，抽吸檢查並未抽取出任何內容物。環口攝影X光片下發現一邊界不清，放射線穿透混合放射線不透之病灶，斷層掃描顯示此病灶呈現3×3公分不規則邊緣之實心腫塊。切片病理檢查高度懷疑為齒源性纖維瘤，遂於全身麻醉下採手術刮除治療，術後病理檢查證實為齒源性纖維瘤，術後病患復原情形良好，門診追蹤迄今一年無復發情形。

Odontogenic fibroma is a rare benign odontogenic tumor in jaw bones which accounts for only 0.1% to 1.5% of all odontogenic tumors and 6.1% if odontomas were not taken into account. Odontogenic fibroma is classified as central and peripheral types according to its location in the jaw bones. Slow growth is a classic feature of this tumor, although cortical bone expansion is seen sometimes, pain is not usually experienced. Apparent swelling or displacement of adjacent tooth and sometimes nerve paralysis are the common reasons for the tumor to be discovered. The treatment choice for odontogenic fibroma is excision, the prognosis is excellent and recurrence is uncommon. Until 2010, only 80 cases of central type odontogenic fibroma were reported in English literature, which outlines its unique entity. Therefore, here we report a case of odontogenic fibroma.
