[|Human|] I have problem with my skin on both legs. On rt leg, there is a distinct round shape, centrally pigmented (same as my skin color) and outer circle has less pigmented than my skin color and its bit shiny but not itchy. Initially, about a 6 months back, it was round, very dry, very itchy and when I scratch it used to become white in color and the skin in the area would fall as flakes. I started using steroids but I still have this problem. On the other leg, it was just the same but there were two circles. Now the two circles have joined and became like an elongated shape. It has similar characteristics: shiny, centrally pigmented (same as my skin color) and the outer regions have lighter skin color. I feel it is spreading outwards. Please advise. i appreciate any response. Thank you.
[|AI|]  Hello, Welcome to Chat Doctor. From your description, the possibilities of your skin problem include psoriasis and Chat Doctor.  You need to consult a dermatologist to confirm the same. A skin biopsy may also be required. Both the conditions benefit for a topical steroid for a few days and also moisturizers. Both have remissions and relapses. However, psoriasis can become more widespread. Hope this helped. Take care.
