Summary
Neoplastic lumbosacral plexopathy, a cancer complication, can cause limb pain and weakness. The "hot and dry foot" is an uncommon but early indicator of metastatic plexopathy, aiding diagnosis.
Area of Science:
- Neurology
- Oncology
- Medical Complications
Background:
- Neoplastic lumbosacral plexopathy is a common, disabling cancer complication.
- Symptoms include limb pain, weakness, and sensory changes, often with tumoral symptoms.
- Autonomic symptoms, like the "hot and dry foot", are less frequent.
Observation:
- Two patients with cancer (prostatic and myxoid liposarcoma) developed lumbosacral plexopathy.
- Both cases presented with a noticeable temperature difference in the affected limb.
- The "hot and dry foot" was observed in these patients.
Findings:
- The "hot and dry foot" is an infrequent autonomic symptom of neoplastic lumbosacral plexopathy.
- This sign can manifest as a clear difference in limb temperature.
- It serves as an early indicator of metastatic plexopathy.
Implications:
- The "hot and dry foot" can be an early diagnostic sign for metastatic plexopathy.
- Recognizing this sign aids in differentiating plexopathy from lumbosciatic radiculopathies.
- Early diagnosis facilitates timely and appropriate cancer treatment strategies.
