RESUMO
Pityriasis rubra pilaris (PRP) is a rare inflammatory dermatosis characterized by hyperkeratotic follicular papules and erythematous-desquamative plaques that tend to progressively evolve into erythroderma. Treatment is challenging given that international guidelines are not available and large-scale trials do not exist. Traditionally, many topical and systemic drugs had been used as consolidated agents; recently, biologicals are gaining increasing importance, promisingly dominating the therapeutic scenario ahead. Herein, we present a case series showing the "past" and the "future" therapeutic approaches to erythrodermic PRP, one case treated with acitretin and nb-UVB phototherapy combination, while the other with ustekinumab, performing also a throughout literature review.

Atopic dermatitis (AD) is a chronic, relapsing, highly pruritic inflammatory skin disease. AD long-term treatment is usually required to control and prevent flares, and patients need a treatment that is safe and efficacious when applied continuously or intermittently over a prolonged period of time. The treatment options should be chosen according to age, clinical features and severity of the disease in every single patient. For the treatment of a chronic disease like AD, sustained tolerability and efficacy of the applied medications are essential. A topical immunomodulator, tacrolimus ointment, provides an alternative to topical corticosteroids without the associated adverse events. Tacrolimus is a macrolide lactone with unique immunomodulatory properties and strong anti-inflammatory activities and can be used without increasing the risk of infection or other non-application site adverse events, and without loss of effectiveness, in patients with AD.
