Pityriasis rubra pilaris (PRP) is a rare skin condition that is of unknown etiology. We present an unusual case of a patient with PRP as the sole initial manifestation of hepatocellular cancer. The course of the patient's illness and management of this case is discussed. Possible reasons for this association are presented.

Erythroderma is a severe and heterogeneous inflammatory skin condition with little guidance on the approach to management in cases of unknown etiology. To guide therapeutic selection, we sought to create an immunophenotyping platform able to identify aberrant cell populations and cytokines in subtypes of erythroderma. We performed high-parameter flow cytometry on peripheral blood mononuclear cells (PBMCs) and whole blood of a patient with refractory idiopathic erythroderma, erythrodermic patients with Sézary syndrome and pityriasis rubra pilaris, and healthy controls.

Ponatinib, a tyrosine kinase inhibitor used for chronic myeloid leukemia and acute lymphoblastic leukemia, can cause rare cutaneous side effects. In this case, a 63-year-old woman developed a pityriasis rubra pilaris-like eruption 1 month after starting the drug. The skin reaction improved with dose reduction and recurred more mildly at a lower dose.

Background: While IL-23 inhibitors, which include guselkumab, tildrakizumab, and risankizumab, are currently FDA-approved solely for the treatment of psoriasis, several other inflammatory skin conditions have been associated with elevated IL-23 levels. The purpose of this review is to summarize and interpret the literature surrounding the off-label uses of IL-23 inhibitors in dermatologic practice.
Methods: We conducted searches on PubMed and for clinical trials, observational studies, case series, and case reports assessing use of the three IL-23 inhibitors for non-psoriatic dermatologic conditions.
