[|AI|]  Hello, Thanks for the query to H.M. Forum. A case of COPD, prostate cancer (operated), with arthritis and main complaint is brownish purplish coloration with pain in left arm.  This sign (symptoms) over the left arm may be due to involvement of lymph node of left arm due to secondaries of prostate carcinoma. I in my few case have seen such type of discoloration, so please consult your oncologist and get his opinion and advise. Rosacea usually spread over face and color is red (cherry type). 2nd reason of these symptoms may be due to sulfa Chat Doctor.
