Desmoid tumors (DTs) are rare locally aggressive benign soft tissue tumors with an estimated annual incidence of two to four new cases per million people. The giant intra-abdominal mass presents a diagnostic challenge that includes a broad differential diagnosis of gastrointestinal stromal tumor (GIST), fibrosarcoma, retroperitoneal fibrosis, and other malignancies from adjacent organs. We report a case of a 38-year-old male patient with a giant intra‑abdominal mass. Magnetic resonance imaging (MRI) of the abdomen and pelvis indicated mucinous cystic neoplasm or gastrointestinal stromal tumor (GIST), but histopathology confirmed it to be a desmoid tumor. The patient was discharged, and on follow-up five months until now, there is no recurrence. This case highlighted the importance of including DT in the differential diagnosis of very large intra‑abdominal masses.
韧带样瘤（DTs）是罕见的局部侵袭性良性软组织肿瘤，估计年发病率为每百万人中有2至4例新发病例。巨大的腹腔内肿块带来了诊断挑战，包括对胃肠道间质瘤（GIST）、纤维肉瘤、腹膜后纤维化以及来自相邻器官的其他恶性肿瘤进行广泛的鉴别诊断。我们报告一例38岁男性患者，其腹腔内有巨大肿块。腹部和骨盆的磁共振成像（MRI）显示为黏液性囊性肿瘤或胃肠道间质瘤（GIST），但组织病理学证实为韧带样瘤。患者已出院，截至目前随访五个月，无复发情况。该病例凸显了在非常大的腹腔内肿块鉴别诊断中纳入韧带样瘤的重要性。
