Lipomas are adipose tumors that are often located in the subcutaneous tissues of the head, neck, shoulders, and back. Lipomas have been identified in all age groups but usually first appear between 40 and 60 years of age. These slow-growing, nearly always benign, tumors usually present as nonpainful, round, mobile masses with a characteristic soft, doughy feel. Rarely, lipomas can be associated with syndromes such as hereditary multiple lipomatosis, adiposis dolorosa, Gardner's syndrome, and Madelung's disease. There are also variants such as angiolipomas, neomorphic lipomas, spindle cell lipomas, and adenolipomas. Most lipomas are best left alone, but rapidly growing or painful lipomas can be treated with a variety of procedures ranging from steroid injections to excision of the tumor. Lipomas must be distinguished from liposarcoma, which can have a similar appearance.
脂肪瘤是脂肪性肿瘤，常位于头部、颈部、肩部和背部的皮下组织。各年龄组均有脂肪瘤病例报告，但通常首次出现于40至60岁之间。这些生长缓慢、几乎总是良性的肿瘤通常表现为无痛性、圆形、可移动的肿块，触摸起来有典型的柔软、面团样的感觉。脂肪瘤很少与遗传性多发性脂肪瘤病、痛性肥胖症、加德纳综合征和马德隆病等综合征相关。此外还有血管脂肪瘤、异型脂肪瘤、梭形细胞脂肪瘤和腺脂肪瘤等变体。大多数脂肪瘤最好不予处理，但快速生长或疼痛的脂肪瘤可以通过从类固醇注射到肿瘤切除等多种方法进行治疗。脂肪瘤必须与外观可能相似的脂肪肉瘤相鉴别。
