[|Human|] I have an odd rash on my lower stomach about where my bra sits, underneath it, and its starting to spread to my stomach, near my shoulders and on my back.  I have had this rash for about 6 months now.  It itches, but is not raised.  Its splotchy and circular.  They appear to grow larger and connect over time.  The color is a faded reddish pink.  I am allergic to anything with sent or dye in them, but have not switched detergent, perfume or anything that comes in contact with that area.  I was wondering what this might be and if I should be worried.
[|AI|]  Hi, As per your descriptions it seems to be a Tina corporal or tricolor, a topic dermatitis, psoriasis, impetigo or herpes or candidiasis. You can undergo routine blood investigations with skin swab tests from the itch area for culture microscopic examination. Treatment is mainly depended on the diagnosis, but you may require topical corticosteroid(clobetasol or beclomethasone) with antifungal cream (fluconazole or itraconazole) with other supportive treatment. You must consult skin specialist for complete clinical examination. Thanks and take care
