摘要

肌纖維瘤是一種非尋常的肌纖維母細胞增生性腫瘤。可呈現單一或多個腫瘤結節於軟組織、骨質、及內臟器官等。顎骨病灶的臨床及影像特徵與許多齒源性和非齒源性腫瘤相似。顎骨肌纖維瘤多為界限清晰，亦偶有浸潤破壞或輪廓不清現象導致誤診及不當治療。本文報告一例發生於十歲女童的下顎肌纖維瘤。病患僅接受局部廣泛性切除手術，術後六年未曾復發。由於相關文獻資料貧乏，故報告本病例詳細臨床徵象，組織病理發現與治療過程以供參考。

Myofibroma is an uncommon neoplasm characterized by myofibroblastic proliferation. The tumor may present as single or multiple nodules of soft tissue, bone, or internal organs. When encountered in the jaws, the lesions exhibit clinical and radiographic features suggestive of several odontogenic and non-odontogenic neoplasms. Myofibromas of the jaws are usually well-demarcated, but sometimes can be poorly delineated or infiltrated that may result in misdiagnosis and mistreatment. In this article, a case of myofibroma of the mandible of a 10-year-old Taiwanese girl is reported. The patient received local wide excision of the lesion and remained disease free with regular follow-up for 6 years. Details of the clinical features, histopathologic diagnosis, and management of the case are provided to augment the paucity of literature available to clinicians managing the rare disease.
