A patient with an intramuscular lipoma (infiltrating lipoma) located within the tongue is presented. There is only one previously reported case of an intramuscular lipoma located within the oral cavity. Because of its infiltrating nature, this tumor may be mistaken for a liposarcoma. Here, as in other sites, the important characteristics serving to distinguish an infiltrating lipoma from a liposarcoma are the absence of lipoblastic proliferation, myxoid differentiation, cellular pleomorphism, increased vascularity, and mitotic activity. Achievement of adequate surgical margins is essential, as the recurrence rate may be as high as 62.5% without complete excision.
本文报告了一例舌部肌内脂肪瘤（浸润性脂肪瘤）患者。口腔内肌内脂肪瘤此前仅有一例报道。由于其浸润性，该肿瘤可能被误诊为脂肪肉瘤。在此处，与其他部位一样，用于区分浸润性脂肪瘤与脂肪肉瘤的重要特征是不存在脂肪母细胞增殖、黏液样分化、细胞多形性、血管增多和有丝分裂活性。获得足够的手术切缘至关重要，因为若未完全切除，复发率可能高达62.5%。
