Aspects of dermatological treatment in psoriasis, acne and hydradenitis chronica suppurativa and skin cancer will be highlighted in this issue. In psoriasis, not only the health care insurance costs but also the out-of-pocket costs are relevant. Costs may differ considerably in different areas of the world. In this issue, the costs in the USA will be presented. In psoriasis, combination treatment is prescribed to the large majority of patients. We have prescribed combination therapy decades ago, but what is the evidence that these combinations are effective and safe? In this issue, the combination of low-dose cyclosporin with calcipotriol betamethasone will be presented.
