A patient with a well-differentiated liposarcoma at the base of the tongue is reported. The patient experienced many local recurrences over 37 years yet remained free of metastases. Liposarcomas of the oral cavity are rare and are not usually included in the differential diagnosis of soft tissue masses in the oral region. As these tumors may occur anywhere that adipose tissue is found, the possibility of a slowly enlarging asymptomatic, grossly well-defined, soft to firm mass being a liposarcoma must be remembered. Because of the difficulties sometimes experienced in histologically distinguishing between low-grade well-differentiated liposarcoma and certain lipomas, any recurrence of a lipoma should be viewed with a great deal of suspicion about the original diagnosis.
本文报道了1例舌根部高分化脂肪肉瘤患者。该患者在37年中经历了多次局部复发，但未发生转移。口腔脂肪肉瘤罕见，通常不包括在口腔区域软组织肿块的鉴别诊断中。由于这些肿瘤可发生于任何有脂肪组织的部位，因此必须记住，缓慢增大、无症状、边界清晰、质地由软至硬的肿块有可能是脂肪肉瘤。由于在组织学上有时难以区分低级别高分化脂肪肉瘤和某些脂肪瘤，因此对于脂肪瘤的任何复发都应高度怀疑最初的诊断。
