[|Human|] My maid has rashes on the skin, which starts as a small spot and then on itching,it becomes a big rash spot @ 1" -2".  It also becomes black in color.  The spot does not have any swelling.  This condition seems to be exists for 6 months now. It has started to show more prominently since last 2-3 months. She has seen a couple of doctors. She was prescribed Tri-o-bloc cream. She used it for 2 -3 weeks and stopped it since its expensive.  The next doctor prescribed Tenovate NM cream, Laveta tab, Betnesol tab and AF 400.  The condition has not improved.  Please advice.
[|AI|]  Tithe data you have provided is insufficient. The most important data here is site. Where is the black spot located? If on face then we are dealing with plasma. But from what I can guess from history you have provided is that the patient has Tina incognito. But ti tell with certainty I need the location of the lesion and if possible a photograph. Treatment of this condition is oral and or topical antifungals for appropriate duration. Incomplete treatment will lead to relapse. Hope it helps Regards Chat Doctor.
