RESUMO
Hidradenitis suppurativa (HS) is an inflammatory skin disease showing a chronic-remitting course. It has been rarely reported that long-term inflammation in HS could lead to serious complications like cutaneous squamous cell carcinoma. Cemiplimab is a fully human antibody immunotherapy that inhibits programmed cell death protein-1, approved for the treatment of locally advanced squamous cell carcinoma, or metastatic squamous cell carcinoma, in patients not eligible for curative surgery or radiotherapy. Herein, we report the case of a 56-year-old patient developing an invasive SCC on longstanding and unresponsive HS lesions successfully treated with cemiplimab.
RESUMO
Circinate (Lapière) psoriasis represents a rare variety of generalized subacute pustular psoriasis clinically characterized by rapid onset of annular circinate lesions with micro-pustules at the borders without classic plaque psoriasis manifestations. Most reported cases have been described in childhood with a relative benign course, fast and long-term remission after treatment. However, the recalcitrant course may result in an important negative impact on patients' quality of life. Many systemic treatments have been reported for the management of moderate to severe forms, with variable clinical outcomes. However, data about the use of biologics in this rare psoriasis subtype are still lacking. Herein, we report the first case of circinate psoriasis unresponsive to methotrexate and almost all classes of biologics approved for psoriasis (anti-tumour necrosis factor (TNF), anti-interleukin (IL)-12/23, and anti-IL-17) which was successfully treated with risankizumab (anti-IL-23).

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.
