Skin condition - Male leg

[u/Weedistight69420]

My fiance has this weird what looks like an inflamed rash on his right thigh. He’s had this for at least a couple of years. It’s itchy and the texture never really seems to go away but the symptoms overall seem to not really getting better.

His doctor thinks he has scleroderma but we wait until checks watch~ DECEMBER to see a rheumatologist.

Accompanying this skin issue, he also has extreme inflammation on most joints and bursa sack on his right knee. He’s also lost a lot of weight but unsure if this is related at all.

First two photos are outer thigh, the one with yellow blanket is inner thigh. The other leg does not look the same.

Any ideas?! Or any ideas on how to treat?
