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.
肿瘤性腰骶丛神经病是癌症患者常见且致残的并发症。其临床表现的特征为疼痛、肌肉无力、单肢或偶尔双肢出现感觉异常并伴有肿瘤症状。自主神经症状较少见，其中之一是“热足与足干”。我们报告两名患者，一名患有前列腺癌，另一名患有黏液样脂肪肉瘤，他们均发生了腰骶丛神经病，作为肿瘤进展的一种表现；在这两个病例中，患侧肢体温度均有明显差异。“热足与足干”虽不常见，但它是转移性丛神经病的早期体征，有助于与椎间孔前腰骶神经根病进行鉴别诊断。
