What causes red dry patches spots on my arms and on scrotum?
Patient: Hi I have itchy red dry patches and spots on my arms and I have one single patch on my scrotum they have been there for about a month, I have had the same thing about a year ago but only on my arms and was diagnosed with pityriasis rosea was wondering if this could be the same thing Doctor: Hi,Most probably you may be having contact allergic dermatitis. Consult the Dermatologist for the perfect diagnosis and proper treatment. As there is itching, allergy is more likely possibility then pityriasis rosea. Apply steroid cream and take oral steroid in tapering dose and antihistaminic under observation of doctor.Hope this helps.Dr.Ilyas Patel, Dermatologist
