Solitary fibrous tumors (SFTs) are a rare type of sarcoma and ubiquitous in nature, occurring anywhere in the body. Although only a few hundred cases have been described so far, certain histological features, such as hypercellularity and high mitotic index, have been associated with a more malignant course. Tumor sizes larger than 10 cm have also been associated with higher recurrence rates. There are clinical recommendations for two distinct patient groups, those with small and benign SFTs or those with large and malignant SFTs. There are few that acknowledge the unique group of those with large but benign tumors. A case involving a 62-year-old man who underwent surgical resection of a large but benign solitary fibrous tumor of the pelvis is described.
孤立性纤维性肿瘤（SFTs）是一种罕见的肉瘤类型，在自然界中普遍存在，可发生于身体的任何部位。尽管迄今为止仅描述了数百例病例，但某些组织学特征，如细胞增多和高有丝分裂指数，与更恶性的病程相关。肿瘤大小超过10厘米也与更高的复发率相关。对于两个不同的患者群体有临床建议，即患有小的良性SFTs的患者或患有大的恶性SFTs的患者。很少有人认识到患有大的但良性肿瘤的独特群体。本文描述了一例涉及一名62岁男性的病例，该患者接受了盆腔大的但良性的孤立性纤维性肿瘤的手术切除。
