Study Design. Case report. The authors documented a patient presenting with multiple cellular schwannomas along the sciatic nerve. The patient had no stigmas of neurofibromatosis. Thirteen tumors were resected via both anterior and posterior approaches.
Objectives. To point out that presacral cellular schwannoma can display multiple occurrences.
Summary of Background Data. Cellular schwannoma, which is a well-recognized variant of benign schwannoma, is often misdiagnosed as sarcoma. The tumor is usually a solitary lesion.
Materials and Methods. Medical history, physical findings, imaging features, and histologic findings were reviewed in a case of multiple cellular schwannomas in the presacral regions.
Results. A 39-year-old woman without any evidence of neurofibromatosis underwent removal of presacral multiple tumors along the sacral nerve root. Nineteen years after the surgery, the tumors recurred with multiple fashion. Thirteen tumors were resected via both anterior and posterior approaches. Immunohistochemical analysis of S-100 protein and Ki-67 were beneficial with respect to differentiation of cellular schwannoma from malignant peripheral nerve sheath tumor.
Conclusions. The present case illustrated that multiple cellular schwannomas can develop in nonneurofibromatosis patients.
