Methods： Between January 1951 and September 2004, 81 patients with retroperitoneal schwannoma were retrospectively analyzed. Results： All cases received operative therapy. Sixty cases （74.1%） received a total resection; 12 cases （14.9%） subtotal resection, and 9 cases （11.1%） exploration. During the surgical operation, a single tumor was found in 77 cases （95.1%）, and multiple tumors in 4 cases （4.9%）. Most of the retroperitoneal schwannomas located beside the spine. The tumor was a fusiform, round or oval mass that was sharply circumscribed and encapsulated. Pathologic results showed all 81 cases were benign schwannoma. In the 4 cases of multiple tumors, 2 （2.5%） were diagnosed as double-primary tumors associated with ascending colon adenocarcinoma and lung squamous-cell cancer. One case recurred postoperatively. Conclusion： Retroperitoneal schwannoma was rare and preoperative diagnosis was difficult. Most of retroperitoneal schwannoma were benign and the surgical treatment was the first choice.展开更多
