摘要

造釉細胞纖維齒瘤為一罕見之混合齒源性顎骨腫瘤，好發於兒童及年輕人。此腫瘤多位於顎骨內，且為無臨床症狀而生長緩慢之腫塊。好發於下顎骨之骨體及上行枝區，於射線影像呈現一周界清晰、內含一個或許多放射不透過性的小塊。
本病例為一12歲男性患者，於下顎骨後牙區發生之造釉細胞纖維齒瘤，直徑約5.5公分。治療方式探外手術，經口外切線將腫瘤分割摘除。病理組織檢查顯示腫瘤以原始結締組織為基質，伴有索狀齒源性上皮組織及分化良好之牙釉質、牙本質結構。患者傷口癒合良好，術後至今九個月，無復發跡象。

Ameloblastic fibro-odontoma is a tumor of mixed odontogenic origin infrequently encountered within the jaw. It occurs predominantly in children and the youth. The tumor is usually asymptomatic and slow-growing. The mandibular body-ramus area is the favored location. Radiographically, the lesion is well circumscribed and radiopaque.
Herein we reported a case of mandibular ameloblastic fibro-odontoma in a 12-year-old boy. Complete extirpation of the rumor was performed via an extraoral approach. Histologically, the tumor was composed of a myxoid connective tissue with strands of odontogenic epithelium and differentiated tissue such as enamel and dentin. Wound healing was uneventful with no evidence of recurrence after a nine-month period of follow-up.
