[Gustatory sweating demonstrated by infrared thermography].
A 35-year-old man, previously healthy except for a grade 1 goitre, sustained a spontaneous left pneumothorax treated with a Bülau drain. When the left pneumothorax recurred 2 months later a left thoracotomy was performed. Two bullae at the lung apex were resected and a pleurodesis performed. After the operation the patient noted hypaesthesia of the dorsum of the left upper arm, mild ptosis of the left eyelid as well as reduced sweat secretion over the left half of the face and the left rib cage. The hypaesthesia improved, but the sympathetic nerve deficits remained. There were no other neurological signs. 9 months later, within one minute of eating a sour apple, the patient developed severe sweating over the left half of the face and the left chest. The reaction was confirmed by infra-red thermography which proved that the skin temperature in the sweating region had fallen to 3 degrees C. The likely cause of localized gustatory sweating is intra-operative damage of the stellate ganglion or its preganglionic nerve connections. Treatment is limited to avoidance of the precipitating gustatory stimulus.
