髂骨弥漫性腱鞘巨细胞瘤一例报告

摘要：Objective To analyze the epidemiology, diagnosis and treatment of the giant cell tumor of the diffuse tendon sheath ( D-TGCT ). Methods A rare clinical study of iliac bone D-TGCT was retrospectively analyzed and the foreign literatures in recent years were reviewed. Results A 12-year-old female with 3 days' right hip pain was admitted to the hospital. After imaging and preoperative examinations, the right iliac bone needle biopsy was performed on the right side. Pathological diagnosis: iliac D-TGCT. Cancellous bone allograft grafting was applied in the tumor cavity. During the operation, it was found that tumors were near the right sacroiliac joint, soft bone cortex, inward destruction of the sacroiliac joint, tenacious sclerotic bone antrum around the iliac bone, unclear boundary, irregular shape. Tumors were removed 2mm against the wall. The tumor cavity was inactivated by iodine and ethanol, and rinsed with distilled water. Allogeneic cancellous bone grafting was conducted. No recurrence or metastasis occurred in the 6 months' follow-up. Conclusions D-TGCT involving the iliac bone is rare. The specificity of imaging is not high and the diagnosis mainly depends on pathology and immunohistochemistry. Radiotherapy and chemotherapy effects are uncertain. Postoperative recurrence rate is high and the patient is in close follow-up.
