Help!! What is this?? I am 22 weeks pregnant and had Morphea in same spot as a teenager - the discoloration and scarring has been there for 15+ years but the red circle rash is new. When this rash first appeared I also had a small itchy bumpy patch on my arm, I’m still itchy on the side/back of my neck, and I’m super itchy where I have stretch marks forming on my hips and thighs. This area on my boob was full of little red bumps originally but it’s smoother looking now. I’ve applied topical steroid cream I had from my last rash for at least 5 days now and nothing is really happening with it. 

I originally thought it was some kind of contact dermatitis but I really have no idea. I stayed at a friends house 2 weekends ago and it is dirty there and they have dogs - my house is significantly cleaner 😬 I also used their soaps/shampoos which are not hat I normally use. The only other net new thing I can think of is I got a pregnancy pillow but I had been using that prior to rash onset. 

Last time I went to the derm was during first trimester and I had a much more widespread rash with small red patches all over my torso that looked nothing like this but was also very itchy. Biopsy came back as spongiotic dermatitis with notes stating it was consistent with eczematous dermatitis.
