This study aimed to address the article by Yang et al., titled “.” The authors reported an extremely rare case of a large atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDL) arising in the gallbladder, diagnosed through imaging and histopathological findings. However, due to the tumor’s exceptional size, the positional relationship between the gallbladder and the tumor remains unclear. In such cases, it is essential to histologically analyze the interface between the tumor and the gallbladder. Additionally, imaging revealed both fatty and non-fatty components, necessitating consideration of dedifferentiated liposarcoma as a differential diagnosis. In light of these factors, this study discusses the specific information required for further evaluation and accurate diagnosis.
本研究旨在探讨Yang等人发表的题为“.”的文章。作者报告了一例极为罕见的发生于胆囊的巨大非典型脂肪瘤性肿瘤/高分化脂肪肉瘤（ALT/WDL），通过影像学和组织病理学检查确诊。然而，由于肿瘤尺寸异常，胆囊与肿瘤之间的位置关系仍不明确。在此类病例中，对肿瘤与胆囊之间的界面进行组织学分析至关重要。此外，影像学显示肿瘤既有脂肪成分又有非脂肪成分，因此需要将去分化脂肪肉瘤作为鉴别诊断考虑在内。鉴于这些因素，本研究讨论了进一步评估和准确诊断所需的具体信息。
