• A patient who had lost weight and had chills, fever, and cough had an enlarging nodule in the upper part of the left lobe of the lung and hyperhidrosis of the right side of his head and trunk. There was no evidence of Horner's syndrome. A lymph node biopsy specimen obtained by mediastinoscopy showed a poorly differentiated metastatic adenocarcinoma. Systemic tumors may induce unilateral hyperhidrosis by stimulation of the contralateral cervicothoracic sympathetic chain.
