Hello.  About 2 weeks ago, my daughter noticed a smooth rash like skin condition that was covering her  groin and upper thigh area.  Aslo behind one knee.  It doesnt itch or bother her in any way.  She said she wouldnt know it was there if she couldnt see it.  Her skin is very sensitive and she has a severe case of karatosis polaris, so I figured she was just having a reaction to something.  However, it has not gone away.  It has lightened some and looks sort of like light brown bruising...like could be caused by gripping the skin too tightly.  The skin looks like it has tiny, faded blood dots..like its been pinched.  Can you please tell me if this sounds at all familiar.  Thank you!!
Hi, Welcome to Chat Doctor forum.  It appears to be the ring worm, or eczema, she may need to use antifungals, and steroid combination creams.  So I advise you to consult a dermatologist for diagnosis and treatment.  I usually prescribe to my patient with such symptoms grisofulvin 500 mg, and dexamethasone, fluconazole, and Neo main. For local application.  Wishing for a quick and complete recovery. Thank you.
