Celluar schwannoma is a very rare benign tumor involving peripheral nerves.
mimicking mailgnant nerve sheath tumor in histological appearance. it is a
clinico-pathological variant of benign schwannoma characterized by a high cellularity.
increased mitotic figures and occasional presence of bone destruction. A 6-month-old
female patient was admitted with progressive quadriparesis. Magnetic resonance imaging
of the cervical spine showed a well-enhancing extramedullary mass on the C4 to C6
area. Total laminectomy was performed on C4-7, and intradural extramedullary tumor
was removed. histologically, the tumor was composed of proliferated spindle cells. Most
of the tumor was composed of Antoni A area with hypercelliar spindle cells arrnaged in
fascicular pattern. The tumor cells showed mild atypism with mitotic figure upto
4/10HPF and diffuse, strong S-100 protein immunostaining. The patient was improved
postopernatively.
