Hello, I have been to several doctors and dermatologists and no one has been able to help my situation. I was always prescribed creams and even tried some home remedies but nothing seems to work.About 7 to 8 years ago, around the age of 10, I started going through puberty. Around the same time, i started developing what seemed to be a rash on my breast. It was dark, brownish red. I assumed it was a bruise and ignored it. Overtime, I noticed it to be growing larger and very itchy, to the point where the itchiness was unbearable. I took it to the experts and they all assume i was born with it, like a birth mark. This brownish red discoloration now take up almost my whole left breast and is now growing on my neck and near my nipple on my right breast. I was told it could be several thing, fungal infection,diabetes... I've done about 4-6 blood tests, they all came out normal. The discoloration is not elevated, there are no bumps or anything risen. The texture is smooth but it is very displeasing to see. Have you ever heard of anything this could possibly be? I would be happy to include pictures since i know my description might not sound like what it truly is. I believed it was acanthosis nigricans but it does not have the folds and what i have is more reddish. My dermatologist also said it wasn't it, but she has no idea what it could be. Any information would be deeply appreciate. Thank you for your time and i look forward to hearing back from you.
