Hello. Thank you for writing to us at Chat Doctor Psoriasis is a chronic skin condition characterized by red, scaly plaques on various body sites particularly extensor skin surfaces like elbow, knee, lower back, scalp etc. Nevertheless, It can involve widespread body areas like the whole of arms and legs and the whole of torso. The disease may relapse after a seemingly complete cure. Extensive psoriasis requires systemic treatment apart from topical treatment. Systemic treatment options include Oral Methotrexate, Oral Cyclosporin, Phototherapy, Oral retinoids e.g. Accretion etc. These systemic treatment options can be used either solely Or may be combined to produce the desired results. Topical treatment modalities for treatment of psoriasis are Emollients, topical potent steroid creams/ointments/lotions (with or without salicylic acid), topical vitamin D analogue ointment/lotions (with or without topical steroids). I suggest him to visit a dermatologist in his region. The doctor will be able to assess the severity of his skin condition and advice accordingly. Regards
