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

These include a variety of diagnoses with certain lesions (for example, ganglion) being more common than others. Some may even be familiar as they are often site-specific. This article aims to provide general practitioners with clear and concise information regarding swellings to be ruled out before suspecting giant cell tumor of tendon sheath. Swellings of the hand are commonly encountered in a general practice with different diagnosis. They may arise from any tissue in the hand including skin, subcutaneous fat, muscle, nerves, vessels, tendon, bone and cartilage. Fortunately, most are benign, asymptomatic and may not require surgical intervention. Ganglions, epidermoid inclusion cysts, giant cell tumours of the tendon sheath, and swellings associated with arthropathy comprise the majority of lesion. This study includes 16 cases which are presented with similar history and presentation of finger swellings as that of giant cell tumor tendon sheath but the final diagnosis has varied.展开更多
