摘要

骨性迷芽細胞瘤為罕見之頭頸部良性腫瘤。本篇報告討論一位21歲女性病患因舌上一無痛突起物而求診，詳細理學檢查後發現為一含柄狀之突起物於舌根處。經全身麻醉手術切除病灶後，病理報告證實為骨性迷芽細胞瘤。術後一年追蹤並無復發病灶。骨性迷芽細胞瘤於組織切片鏡檢是正常組織異位增生所致，常與舌側軟組織類似，唯一差異是病理組織切片下可見在複層上皮下，有已發育的哈氏管。骨性迷芽細胞瘤在手術切除後極少復發。提出此病例以供研究及治療之參考。

Osseous choristoma is a rare benign lesion in head and neck region. Here, we report a case of osseous choristoma on dorsum of the tongue in a 21 year-old female who presented with an asymptomatic pedunculated nodule on the posterior third of the tongue. She underwent total excision of the lesion under general anesthesia and there were no complications upon 2 weeks follow-up and no recurrence noted 1 year post-operatively. In reviewing previous articles, osseous choristomas are proliferations of the histopathologically normal tissue in an ectopic location. They may mimic other benign lingual soft tissue swellings and the only determinant of these lesions is their histopathology where it consists of developed harversian canal system beneath the stratified epithelium. They are benign and rarely recur after excision.
