We reviewed the topic of atypical lipomatous tumors including definition, diagnosis and management, with special emphasis on head and neck location and to report on the management of a rare case located in the temporalis muscle. Atypical lipomatous tumors/well-differentiated liposarcomas (ALT/WDLS) are rarely reported in the head and neck. Their behavior dictates a complete resection. Resection with a safety margin is sometimes needed according to the histological characteristics. Tumors located to the masticator space can be accessed through a mucosal approach achieving relative safety to the facial nerve. ALT constitute a group of tumors of a borderline behavior. Their management can be affected by some histological criteria and by their location in the head and neck region where vital structures can be affected.
我们回顾了非典型脂肪瘤性肿瘤的相关主题，包括定义、诊断和治疗，特别强调了头颈部的发病部位，并报告了一例位于颞肌的罕见病例的治疗情况。头颈部非典型脂肪瘤性肿瘤/高分化脂肪肉瘤（ALT/WDLS）的报道较少。其生物学行为要求进行完整切除。根据组织学特征，有时需要切除安全切缘。位于咀嚼肌间隙的肿瘤可通过黏膜入路进行手术，以确保对面神经的相对安全。ALT属于一组生物学行为介于良恶性之间的肿瘤。其治疗可能会受到一些组织学标准以及肿瘤位于头颈部这一可能影响重要结构的部位的影响。
