I have rare sarcoid disease, probable lupus, suffer scalp/ears seborrhea that’s out of control?

46yo female I have autoimmune disease-rare form of sarcoid and probable lupus. In the last year I have had an impossible scalp/ears seborrhea that nothing will help and its spreading now to almost entire scalp. In the last 6 mos developed a couple of lesions; derm was slightly dismissive about my concerns of all this being related to my autoimmune processes. Bx showed psoriasform spongyatic dermatitis; now I am developing them everywhere….its like my skin is out of control. Are these problems likely systemic and related to the sarcoid or lupus?
