Is this Post Inflammatory Hyperpigmentation or something else?

Please help. I am a 13 year-old African American female. I had a bad allergic reaction to a soap I was using and my skin had gotten red, felt like my skin was buring, and I was scratching my skin to the point of welps. Soon after my skin healed , these spots are all over my body. They donot  itch or irratate in any way. My dermotologist prescribed Minocyclin, it did help after 2 weeks but I had to stop taking it due to side effects. They are also not quite sure what really caused it. It's really been hard on me with my skin like this. Any suggestions?

Please and Thankyou.

Hello,
Apart from post inflammatory hyperpigmentation and pityriasis versicolor, schamberg’s disease or vasculitis also needs evaluation and should be ruled out by means of a biopsy skin. It is benign dermatoses with purpura due to leaking from capillaries close to the skin surface.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

Well can Schamberg's disease cause low iron due to the leaking blood vessels?

[Bhupinder Kaur, MD]

Hello,
Schamberg disease is caused by leaky blood vessels and is basically caused by caused by bleeding of tiny capillaries in the skin. This will not cause anemia because the process occurs gradually. When the leaked blood is reabsorbed yellow-brown iron deposits are left in the skin which cause a brown stain.

I hope it helps. Take care and regards.
