<s>[INST] Sudden onset of rash 49 years of age. Male. Elevated monocytes, consistently elevated WBC , slightly elevated HGB. Rash first appeared aprox. 3 years ago. Come and go quickly without treatment. Started on face and appeared as dermatitus. Also somtimes looked like red blotches and streaks. Next appeared on hands and seemed to be eczema . Currently on arms and legs. Buttocks . Now being told it is psoriasis . Itching intense and antihistamines do not help. Current ointments (various) no effect and somtimes make it worse. I do not believe the dermatologist is correct. What does this sound like and who should I consult? [/INST] Hi psoriasis will not be due to sudden onset.it lesions are very typical round to oval patch with slivery white scales and on removing pinpoint bleeding occurs.ur description does not suite psoriasis.it can be infective  eczematous dermatitis.apply regular moisteriser and topical antibiotic over the lesions.antihistamine and antibiotic can cure it </s>
