hi. i am on accutane and this is my 3rd month and in the first month of taking accutane a small coin size patch of raised skin appeared on my back. i asked the dermatologist what it was he said it was nummular eczema the first time and gave me vanos but it didnt really help. the following appointment (the second month) it was 3 times larger..i have never had eczema before and there is no family history of it. i have been using lotrimin because the doctor told me it was or could be ringworm, it sorta help with the itching but the size grew. Could this just be eczema caused by accutane or something else?
