Lipomas are superficial tumors that occur primarily in the subcutaneous region and very rarely occur deeply within or between the muscle layers. No reports to date have described cervical lipomas in patients with head and neck cancer who underwent neck dissection. We herein report a case involving a 72-year-old woman with supraglottic carcinoma complicated by a cervical lipoma who underwent simultaneous neck dissection and lipoma removal. The lipoma was a deep-seated intermuscular lipoma arising in the longus cervicis muscle. We initially considered that the lipoma would be removed en bloc with neck dissection, but the imaging findings clearly indicated that the tumor was located more deeply than the prevertebral layer of the deep cervical fascia and outside the range of neck dissection. The lipoma was removed by incision of the prevertebral fascial layer following neck dissection, and no complications occurred.
脂肪瘤是主要发生在皮下区域的浅表肿瘤，极少发生在肌层内或肌层之间。迄今为止，尚无关于接受颈部清扫术的头颈癌患者发生颈部脂肪瘤的报道。我们在此报告一例病例，一名72岁声门上癌合并颈部脂肪瘤的女性患者同时接受了颈部清扫术和脂肪瘤切除术。该脂肪瘤是起源于颈长肌的深部肌间脂肪瘤。我们最初认为脂肪瘤将与颈部清扫术一并整块切除，但影像学检查结果清楚地表明，肿瘤位于颈深筋膜椎前层的更深处，超出了颈部清扫的范围。在颈部清扫术后，通过切开椎前筋膜层切除了脂肪瘤，未发生并发症。
