Liposarcoma is the most common soft tissue malignant tumor. It mostly arises in the subcutaneous tissue of shoulders, limbs and neck, and retroperitoneal space, but head occurrence is very rare. Atypical lipomatous tumor (ALT) is a well-differentiated liposarcoma (WDLPS) and constitutes 40-45% of all liposarcoma cases. A case of 57-year-old woman with a tumor of the left cheek, causing a discreet face asymmetry is presented. The tumor was soft and caused no tenderness. The patient reported no previous injury of the region. Fine-needle aspiration biopsy (FNAB) revealed atypical cells suspected of liposarcoma. MR examination showed fascicles of adipose tissue, which made the left cheek prominent. The patient was operated under general anaesthesia. Adipose tissue of the left cheek was removed. Postoperative course was uneventful. The final histopathological diagnosis - was atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDLPS). The patient remains under laryngological care. No recurrence of the disease has been observed during the 5 years follow-up.
脂肪肉瘤是最常见的软组织恶性肿瘤。它大多起源于肩部、四肢和颈部的皮下组织以及腹膜后间隙，但发生于头部的情况非常罕见。非典型脂肪瘤性肿瘤（ALT）是一种高分化脂肪肉瘤（WDLPS），占所有脂肪肉瘤病例的40 - 45%。本文介绍了一例57岁女性，其左脸颊有一肿瘤，导致面部轻微不对称。肿瘤质地柔软，无压痛。患者称该区域既往无损伤史。细针穿刺活检（FNAB）显示怀疑为脂肪肉瘤的非典型细胞。磁共振检查显示脂肪组织束，使左脸颊突出。患者在全身麻醉下接受手术。切除了左脸颊的脂肪组织。术后过程顺利。最终组织病理学诊断为非典型脂肪瘤性肿瘤/高分化脂肪肉瘤（ALT/WDLPS）。患者仍在接受喉科护理。在5年的随访期间未观察到疾病复发。
