Ossifying Fibromyxoid Tumor of the External Ear Canal-A Case Report
外耳道骨化性類纖維黏液瘤－病例報告
摘要
軟組織骨化性類纖維黏液瘤是近來提出一少見的間質性腫瘤。此腫瘤雖在臨床表現上為良性，但也可能惡性變化，後者突生的機會較少。之前關於骨化性類纖維黏液瘤的病例報告多為發生在四肢且病灶生長緩慢，此腫瘤雖然看似無侵襲性，但是易局部復發。我們提出一軟組織骨化性類纖維黏液瘤的病例報告，此病例為發生在外耳道之病灶，為之前所未曾提出過的發生位置。病患主訴右耳聽障合併持續耳漏及疼痛，在接受手術切除此右外耳道腫瘤後，病患症狀改善，術後追蹤情況良好。文章中並針對此疾病過去其它文獻上的內容作整理。

Ossifying fibromyxoid tumor (OFMT) of the soft parts is an uncommon, recently described mesenchymal neoplasm. Clinical behavior of this rare neoplasm probably varies from benign to truly malignant, although the latter possibility is extremely low. Prior reports of OFMT characterized it as a slow-growing lesion with a propensity to occur in both the upper and lower extremities. Although this is an indolent tumor, local recurrence has been reported. We report on a 14-year old boy with OFMT in the external ear canal, a hitherto unreported location of this neoplasm. This patient complained of right-sided hearing impairment with persistent otorrhea and ear pain. There was no local recurrence 6 months after complete local excision of the mass. In addition, we review some current knowledge of this distinct neoplasm.
