Case Reports
Castleman's disease in the retroperitoneal space mimicking a paraspinal schwannoma: a case report.
Castleman's disease is a rare disease characterized by lymph node hyperplasia. Its occurrence in the retroperitoneal space has rarely been reported, making its preoperative diagnosis difficult. Here, we report a case of retroperitoneal Castleman's disease, which radiologically resembled paraspinal schwannoma. ⋯ Although a dumbbell-shaped mass in a paraspinal region is indicative of a schwannoma for orthopedic surgeons, the possibility of Castleman's disease should be considered if a central low-signal area in fissured and a radial pattern is detected on computed tomography or magnetic resonance imaging. Appropriate preparation for massive bleeding during the treatment of Castleman's disease, including angiography and embolization, would be helpful for performing surgical procedures safely.

Comparative Study
A comparison of cyst wall curettage and en bloc excision in the treatment of aneurysmal bone cysts.
The recurrence rate after aneurysmal bone cyst (ABC) treatment is quite high despite its benign nature. In ABC therapy, curettage is the treatment of choice; en bloc excision results in a lower recurrence rate, but more extensive reconstructive surgery is needed with associated morbidity. The aim of the present study was to compare the outcomes of the two treatment options. ⋯ Curettage is a standard procedure in ABC management. En bloc excision is another option, albeit more technically demanding, that may be considered in recurrent lesions with extensive bone destruction or for cysts in an expendable location.
