[Human peripheral neurolymphomatosis (reticuloendothelial polyradiculoneuritis)]

Area of Science:

• Neurology
• Pathology
• Oncology

Background:

• Reticulo-endotheliosis is a rare condition affecting the nervous system.
• Peripheral neurolymphomatosis presents a diagnostic challenge, often mimicking other neuropathies.

Observation:

• A 53-year-old female presented with facial palsy, progressive limb weakness, paresthesiae, and pain.
• Clinical findings included polyradiculoneuritis with cranial nerve involvement (oculomotor, facial, trigeminal).
• Autopsy revealed pathological changes limited to cranial and spinal roots and ganglia.

Findings:

• Histopathology showed intense infiltration by lymphocytes, histiocytes, plasmocytes, and macrophages with increased reticulin.
• Specific nerves and ganglia affected included the oculomotor nerve, Gasserian ganglia, trigeminal nerve, and lumbosacral nerves/ganglia.
• The patient succumbed to bronchopneumonia 10 months after symptom onset.

Implications:

• This case highlights the importance of considering peripheral neurolymphomatosis in the differential diagnosis of polyradiculoneuritis.
• Accurate diagnosis is essential for appropriate management and treatment strategies.
• Further research into neurolymphomatosis can improve patient outcomes and understanding of rare neurological conditions.
