肌纖維瘤藉由纖維母細胞,肌纖維母細胞或二者之增生為一異質疾病。孤立型肌纖維瘤與多發型肌纖維瘤病具有相同臨床及組織病理學特徵。它們典型地發生於早嬰兒期且有時發生於成人期。它們典型地好犯皮下組織,但有時肌肉,骨頭,肺,腸,或顱內延伸亦可見。但肌纖維瘤於口腔內罕見。本病例報告提出一位六歲男孩罹患左下頜肌纖維瘤,經切除後癒後良好,現仍門診追蹤治療,因病例之稀少,提出報告。
Myofibroma is a heterogenous disorder characterized by the proliferation of fibroblasts, myofibroblasts, or both. Solitary form myofibroma and multiple form myofibromatosis possess the same clinical and histopathological features. They typically occur in early infancy and sometimes in adult. They typically involve skin and subcutaneous tissues, but sometimes muscle, bone, lung, intestine or intracranial extension. But, myofibroma is rarely found in the oral cavity. In this case report, we report a case of oral myofibroma of a six- year-old boy. Because the rarity of the case, we report it.
