Dedifferentiated liposarcomas (DDLPS) are rare, high-grade malignancies that usually originate in the retroperitoneum. Frequently, they present as asymptomatic masses, abdominal distention, abdominal pain, and weight loss. They tend to grow significantly and are usually large in size at the time of diagnosis. Surgical resection is the mainstay of treatment; however, local recurrence is common. When unresectable, they can invade local structures and produce a significant mass effect on the adjacent organs. Here we present the first case of malignant gastric outlet obstruction (MGOO) and acute pancreatitis from a retroperitoneal DDLPS.
去分化脂肪肉瘤（DDLPS）是一种罕见的高级别恶性肿瘤，通常起源于腹膜后。它们常表现为无症状肿块、腹胀、腹痛和体重减轻。肿瘤往往生长迅速，确诊时通常体积较大。手术切除是主要的治疗方法；然而，局部复发很常见。当无法切除时，它们可侵犯局部结构并对邻近器官产生明显的占位效应。在此，我们报告首例由腹膜后DDLPS引起的恶性胃出口梗阻（MGOO）和急性胰腺炎病例。
