[|Human|] Hi. My 18 yr old son noticed his left epitrochlear node swollen on June 15th while we vacationed in Cayman. He was on 40 mg accutane twice a day. He admitted to drinking while there. He had drastic increase in liver enzymes. He has been off accutane for a month. The numbers are back to normal now on July 22. However, he has lost 10% of his body weight and is tired all the time. What could be the cause of the node being swollen?
[|AI|]  According to the history given in the case, the symptoms and the lab findings are suggestive of some sort of liver disorders like Hepatitis A or B. The causes of isolated enlarged lymph node (epitrochlear) are many. In the setting of raised liver enzymes with a history of alcohol intake and significant weight loss of about 10% are indicative of some chronic disease which has to be ruled out by consulting the physician or gastroenterologist. Regards!
