The topic Cellular Neurolemoma you are seeking is a synonym, or alternative name, or is closely related to the medical condition Cellular Schwannoma.

Quick Summary:

• Schwannomas are a group of tumors that arise from the Schwann cells around the nerves; these tumors are essentially nerve sheath tumors. They are commonly seen in young, middle-aged, and slightly older adults
• There are various histological types of schwannomas, which include:
  • Cellular Schwannoma
  • Plexiform Schwannoma
  • Microcystic (Reticular) Schwannoma
• Cellular Schwannoma is a subtype of schwannoma that has certain characteristic features, when examined under a microscope by a pathologist. The tumor is mostly located around the vertebra (paravertebral sites), in the pelvis, or in the retroperitoneal region
• Cellular Schwannomas are typically benign like conventional schwannomas. Currently, no causative factors have been identified for tumor formation. In case of multiple tumors (that are in a minority), the risk factors for the tumor include the presence of NF2 and a positive family history
• Cellular Schwannomas may be asymptomatic (in many cases) or symptomatic. The signs and symptoms are commonly based upon the location of the tumor and can be wide-ranging. It depends on the nerve or region being affected
• In very rare cases, Cellular Schwannomas are known to develop into malignant tumors. The tumors can also compress the nerve on which it lies and cause nerve dysfunction
• In a majority of cases, a complete excision by surgery can be curative and the prognosis of Cellular Schwannoma is excellent. However, the prognosis may be influenced by factors that include the tumor location, the presence of NF2, and if any malignant transformations are noted
