Angioleiomyoma in Right Lingual Gingiva-A Case Report
下顎舌側牙齦之血管平滑肌瘤－病例報告
摘要
平滑肌瘤(leiomyoma)為一種源由於肌肉細胞所形成之良性軟組織腫瘤，在三種平滑肌瘤中，衍生於動靜脈血管之血管平滑肌瘤(angioleiomyoma)的原發性口腔病變亦是少見。根據文獻統計，口腔平滑肌瘤約只佔所有腫瘤之0.06%，其中約66%屬於血管平滑肌瘤。臨床表現多呈現為單一且緩慢生長之型態，極少疼痛。早期惡性轉變機率低，亦少致死。診確定斷須由特殊之鏡下表徵，包含增生肌肉細胞群，圍繞著擴大之血管腔。本病例報告－中年女性，求診時為下顎齒齦區之慢速增生牙齦腫塊，經入院詳察後診斷為血管平滑肌瘤。本文將就血管平滑肌瘤之臨床表現、病理組織表徵及治療方式作一討論。
並列摘要
Leiomyomas are benign soft tissue neoplasms that arise from smooth muscle. There are three distinct types of leiomyomas: piloleiomyomas, angioleiomyomas, and genital leiomyomas, which reflect the most origin of the smooth muscle tumor and correspond to the histologic or anatomic site. Angioleiomyomas, as we present here, originate from smooth muscle within the walls of arteries and veins. Although some cases are reported in the gastrointestinal tract, larynx, and brain, oral angioleiomyomas are infrequently found. Malignant transformation probably does not occur, and therefore, they do not affect mortality directly. However, careful histologic examination is still necessary to distinguish these benign lesions from their malignant counterparts due to different prognosis. Here, we present a case of angioleiomyoma found attached to the lower gingival. Clinical and histological presentation of angioleiomyomas with its treatment will be discussed in this article.
