Pruritus: An Overlooked Symptom of Spinal Tumors
Abstract
Background
Chronic itch is often associated with pain due to its complex nature. Neuropathic pruritus is defined as a debilitating form of chronic itching, about which not much is known to date. This condition may develop as a result of various neurological events and is associated with damage to the somatosensory nervous system, accounting for approximately 10% of chronic itching cases. Syringomyelia, transverse myelitis, radiculopathies, thoracic spine masses, brain tumors, strokes, and abscesses are among the conditions associated with neuropathic itching to date.
Case presentation
A 65-year-old female patient, with no known diseases and no regular medication usage, presented with a complaint of itching that had been ongoing for the past two years. Itching initially started in approximately five cm areas on the bilateral below-knee flexor surfaces. The patient, whose complaints persisted, was referred to the internal medicine outpatient clinic by dermatology. On physical examination, erythematous excoriated papules were observed in the areas affected by itching. The patient's blood sugar, liver and kidney function tests, complete blood count, erythrocyte sedimentation rate, thyroid function tests, urinalysis, stool parasitology were all normal or negative. The patient reported a sensation of coldness in the same area, was referred to neurosurgery to investigate the etiology of possible neuropathic itching. The patient's spinal imaging, revealed a spinal mass. She underwent surgery performed by a neurosurgeon, during which the spinal mass was completely removed. She reported that her itching had completely disappeared post-operatively.
Conclusions
The concept of itching as a variant of pain is not very new. Any damage occurring in the central nervous system or peripheral nervous system that affects the neurons responsible for transmitting and processing itch can lead to neuropathic itching. Focusing on spinal cord pathologies, any condition that damages the spinal cord may cause itching, depending on the level of damage. In cases of itching with dermatomal localization, where pain, hot or cold sensations, and paroxysmal itching are present, additional imaging methods or investigations for etiology should be performed.
