We describe a case of a 57-year-old man referred to an oral maxillofacial surgeon for a nontender, large intramuscular tongue mass. A computed tomography scan with contrast showed a homogenous right tongue intramuscular fatty mass measuring 3.8 cm × 2.8 cm in the axial dimension and 2.2 cm in the craniocaudal dimension. Histologic examination revealed multiple lobulated sections of mature adipocytes and occasional entrapped skeletal muscle fibers. The final pathologic diagnosis was intramuscular lipoma. Although lipomas account for approximately 50% of all soft tissue neoplasms, intramuscular (infiltrating) lipoma of the tongue is exceedingly rare.
我们描述了一例57岁男性患者，因舌部出现一个无痛性、较大的肌内肿物而被转诊至口腔颌面外科医生处。增强计算机断层扫描显示，在轴向层面上，右侧舌部肌内有一个均匀的脂肪性肿物，大小为3.8厘米×2.8厘米，颅尾径为2.2厘米。组织学检查显示，肿物由多个分叶状的成熟脂肪细胞组成，偶尔可见包绕的骨骼肌纤维。最终病理诊断为肌内脂肪瘤。尽管脂肪瘤约占所有软组织肿瘤的50%，但舌部的肌内（浸润性）脂肪瘤极为罕见。
