I have small brown pigmented lesions around my ankles which have been there for a couple of years. I do have itching around my ankles rarely, but not too often. I do have sensitive skin and my epidermis gets peeled off if I scratch too vigorously after an insect bite. I don't have any such pigmentation anywhere else on the body. I also don't have a job in which I am required to stand at one place for a long time. Please if you have any idea what problem it might be, please tell me the differentials. Thanks.
