[|Human|] my 11 year old son was diagnosed with lichen planus for almost a year now. The symptoms appeared on the arms and legs and have covered a wide area. he is about 1.7 metres tall and weighs about 48kg. His has always had a clean bill of health, with the exception of sensitive skin that he would often break by scratching. the use of dermovate has helped but left stretch marks on the skin. Someone just brought me calamine lotion and dermarest psoriasis. Can i use them on the skin?
[|AI|]  If your son has had lichen plans for a year, it's better to do a biopsy and confirm it because it can be diagnosed specifically by biopsy of the lesion, a simple procedure. Once the diagnosis is confirmed, It's simple to manage with antihistamines to stop the itchiness and if large lesions derogate will surely help .as long as it is limited to skin and not involved oral mucosa, flagyl is not needed.
