Liposarcomas are the most common type of mesenchymal neoplasm in soft tissue sarcomas. Although they frequently develop at the lower limbs or retroperitoneum, cases arising from the mediastinum are rare. Furthermore, the incidence of the inflammatory subtype of well-differentiated liposarcoma is known to be low. We experienced a case of a middle mediastinal liposarcoma in a 68-year-old woman. The tumor, which was completely resected, was 92 mm in diameter. The tumor consisted of two different imaging components that showed different growth and which were diagnosed as the lipoma-like subtype and inflammatory subtype of well-differentiated liposarcoma. To the best of our knowledge, this is the first report of a well-differentiated inflammatory liposarcoma arising from the middle mediastinum.
脂肪肉瘤是软组织肉瘤中最常见的间充质肿瘤类型。尽管它们常发生于下肢或腹膜后，但起源于纵隔的病例很少见。此外，已知高分化脂肪肉瘤的炎症亚型发病率较低。我们遇到了一例68岁女性的中纵隔脂肪肉瘤病例。该肿瘤被完整切除，直径为92毫米。肿瘤由两种不同的影像学成分组成，表现出不同的生长方式，被诊断为高分化脂肪肉瘤的脂肪瘤样亚型和炎症亚型。据我们所知，这是首例起源于中纵隔的高分化炎症性脂肪肉瘤报告。
