<s>[INST] My husband seems to get this blotchy rash on his face, back, chest and it's starting to go on his arms when he drinks. It always starts in his ears and face and he complains about being hot when the rash starts. He only drinks beer and he could have 2 beers or 6 beers, it happens either way. It seems to go away faster if he drinks a lot of water. The rash doesn't itch or hurt, and it's not bumpy. I also have noticed that it has gotten much worse as he ages. Any idea what this is? [/INST] Hi,It may be pellagra like dermatitis due to alcohol. Consult the dermatologist for the perfect diagnosis and proper treatment. I would recommend to give him niacin containing tablets and apply mild steroid cream. Exposure to sun rays should be avoided. Tell him to stop alcohol.. even beer.Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Ilyas Patel, Dermatologist </s>
