MRI showed that an elliptical abnormal signal was observed over the infrapatellar region of the right knee. We directly do arthroscopy to remove the tumor. An oval irregular mass of about 2.0 cm × 1.5 cm × 1 cm in the right knee joint was found. It was hard and had a dark red surface and the pedicle of the mass was connected with the joint capsule and infrapatellar fat pad. Nodular GCT-TS occurs less frequently in large joints than the small joints of the fingers and toes. The current report demonstrates the unique characteristics of the GCT-TS that extends around the ankle and invades the knee and proximal humerus.展开更多

Histologically these tumors are composed of multinucleated giant cells, polyhedral histiocytes, fibrosis and hemosiderin deposits. Marginal excision of giant cell tumor of the tendon sheath is the treatment of choice. We present a case of xanthoma of flexor pollicis longus tendon presented as a single enlarging mass in volar aspect of left thumb. After clinical diagnosis, work-up is done with ultrasound, FNAC and excision biopsy.展开更多

目的探讨腱鞘纤维瘤(fibroma of tendon sheath,FTS)的临床病理学特征。方法对39例FTS的临床表现、影像学及病理学特征进行观察。结果男性24例(61.54%),女性15例(38.46%),男女比为1.6∶1,年龄5~69岁,平均34.56岁。74.36%的病例累及上肢...目的探讨腱鞘纤维瘤(fibroma of tendon sheath,FTS)的临床病理学特征。方法对39例FTS的临床表现、影像学及病理学特征进行观察。结果男性24例(61.54%),女性15例(38.46%),男女比为1.6∶1,年龄5~69岁,平均34.56岁。74.36%的病例累及上肢,尤以掌指部为主。临床上,66.67%病例表现为局部无痛性缓慢生长的肿块,33.33%病例伴局部压痛、肿痛症状。10.26%病例曾有局部外伤史,患者术后复发率为14.29%。以MRI为代表的影像学成像显示病变与肌腱、腱鞘或关节囊紧密相连。大体上,病变包膜纤薄或无包膜。镜下病变呈分叶状,每个小叶由稀疏散在的纤维母细胞、裂隙状血管腔隙和大量玻璃样变胶原间质所组成。部分病变形态多样,局部与促结缔组织增生性纤维母细胞瘤、纤维组织细胞瘤或纤维瘤病、结节性筋膜炎及微静脉型血管瘤病变相似。免疫组化示所有成分均表达vimentin,部分梭形及星形细胞表达α-SMA、calponin及CD163,少数病变局灶弱阳性表达β-catenin(胞质)、CD68、MSA及h-Caldesmon,裂隙状腔隙内衬扁平细胞表达CD34、CD31及FⅧRAg,提示为血管性腔隙。结论 FTS是一种相对少见的发生于肌腱、腱鞘或关节滑囊的良性纤维母/肌纤维母细胞增生性病变。典型的FTS多发生于青年人及成年人,以男性居多,好发于上肢,掌指部占多数,少数病变切除后可复发。展开更多
