Abstract:
Patients with neurolymphomatosis show lymphoma cells within the peripheral nerves, nerve root/plexus, or cranial nerves. However, most neurolymphomatosis patients show lymphomatous infiltration not only in the peripheral nervous system (PNS), but also in the meninges, Virchow-Robin space, and brain parenchyma. Here, we report a 74-year-old woman with diffuse large B-cell lymphoma presenting with motor-sensory-autonomic polyneuropathy and multiple cranial neuropathies. A diagnosis of neurolymphomatosis was made by sural nerve biopsy. Postmortem examination indicated that lymphoma cell infiltration in the nervous system was confined to the PNS with no involvement of the central nervous system, including the meninges. This was a very rare case of B-cell neurolymphomatosis with lymphomatous infiltration confined to the PNS, suggesting specific affinity of the lymphoma cells for the PNS in this patient.

Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...
