Symmetrical lipomatosis is characterized by symmetrical infiltration of adipose tissue into the head, neck, or upper trunk. By contrast, oral involvement is extremely rare. The present report describes a case of symmetrical lipomatosis of the tongue (SLT) presenting as macroglossia. The patient was a 63-year-old Japanese male who developed progressive dysarthria secondary to enlargement of the tongue. The patient's medical history was notable for alcoholic hepatitis and hyperlipidemia. Marginal glossectomy was performed on both sides of the tongue to achieve volume reduction and restore normal speech. Histopathologic examination of the resected tissue revealed diffuse infiltration with adipose tissue lacking a fibrous capsule. The patient's postoperative course was uneventful, and he remained free of recurrence or regrowth and functional deficits at the 6-year follow-up time point.

We studied the effects of electro acupuncture stimulation of Baxie on local tolerance as an index of cold induced vasodilation (CIVD). The subjects consisted of 22 healthy adult volunteers. The skin temperature and skin blood flow in the middle finger were simultaneously examined before, during, and after immersion of the finger in cold water. Electroacupuncture stimulation at 1 Hz with a 66 to 100V intensity was performed for 5 minutes. Experiments of no stimulation and electroacupuncture stimulation were conducted on the same subject on different days.
The results revealed the following:
1. CIVD was caused by rapid increase of skin blood flow during immersion of the finger in cold water.
2. The minimum skin temperature, minimum skin blood flow, maximum skin blood flow, mean skin temperature in the rising phase of skin temperature, and the index of resistance to frostbite of the electroacupuncture stimulated group were higher than those of the unstilmulated group, and rates of skin temperature increase and decrease during immersion of the finger in cold water in the electroacupuncture stimulated group were significantly higher. These results show that electroacupuncture stimulation increases local cold tolerance in the finger.
