benign collagen rich epithelioid nerve sheath tumor in cervical spinal cord: a case report

Tumors that originate from the nerve sheath comprise diverse groups -perineuroma,neurofibroma and schwannoma. the epithelioid variant of these tumors is uncommonand mostly seen in malignant counterparts. although this type of morphology is wellrecognized in peripheral nerve sheath tumors, its presence in the central nerves is rarelyreported. very few cases of nerve sheath tumors have been reported with collagen-richstroma. here we report an extremely rare case of nerve sheath tumor with epithelioidmorphology and collagen rich stroma. to the best of our knowledge this finding in thespinal cord has not been reported thus far.
