title: [Neoplastic lumbosacral plexopathy and "hot foot"].
abstract: Neoplastic lumbosacral plexopathy is a frequent and disabling complication in subjects with cancer. Its clinical presentation is characterized by pain, muscle weakness, sensory complaints in one or occasionally both limbs associated with the tumoral symptoms. The presence of autonomic symptoms is less frequent; one of these is the "hot and dry foot". We present two patients, one with prostatic cancer and the other with myxoid liposarcoma, who developed a lumbosacral plexopathy as a manifestation of the extension of the neoplastic process; in both cases there was in addition a clear difference in the temperature of the affected limb. Although infrequent, the "hot and dry foot" it constitutes an early sign of metastatic plexopathy which facilitates the differential diagnosis with preforaminal lumbosciatic radiculopathies.
