Cytokine Profiling of Erythroderma Biopsies Reveals Types 2 and 17 Immune Activation Status.

Background: Erythroderma is a dermatologic condition characterized by widespread red and scaly skin. The causes include, but are not limited to, psoriasis, eczema, drug eruptions, pityriasis rubra pilaris (PRP), and cutaneous T-cell lymphoma. Most of these are typified by Type 2 (e.

Off-label dermatologic uses of IL-23 inhibitors.

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.

Uncommon Presentation of Pityriasis Rubra Pilaris of the Scalp: Clinical, Trichoscopic, and Histopathologic Features and Review of the Literature.

Pityriasis rubra pilaris (PRP) presents a diagnostic challenge due to its varied clinical manifestations and the scarce literature on scalp involvement. This article presents a case report of a 59-year-old female with PRP solely affecting the scalp, detailing its clinical, trichoscopic, and histopathological features. Trichoscopy revealed a novel finding of white-silvery scales forming hair casts with a triangular shape, distinct from the existing literature.

Erythroderma in the elderly.

Erythroderma is the end-stage condition caused by various inflammatory diseases, presenting with widespread generalized coalesced erythema on the trunk and extremities. Erythroderma is not a disease itself, but rather is a symptom expressing erythrodermic condition, which is frequently associated with inguinal lymphadenopathy, chills, and mild fever. The clinical characteristics include sparing the folds of the trunk and extremities (deck-chair sign), and cobblestone-like disseminated grouping prurigo; however, the deck-chair sign is not specific to papulo-erythroderma (Ofuji disease).

Long-Standing Remission After Tildrakizumab Treatment in a Case of Refractory Type I Pityriasis Rubra Pilaris in a Breast Cancer Patient.

Pityriasis rubra pilaris (PRP) is a rare chronic inflammatory skin disease characterised by follicular keratotic papules and perifollicular erythema coalescing into orange-red scaly plaques, and palmoplantar keratoderma. Characteristic islands of sparing are usually observed. A standardised therapeutic approach is lacking owing to the infrequent occurrence of this disease.

Pityriasis Rubra Pilaris and underlying malignancy.

A 59-year-old man presented with a five-month history of widespread, salmon-colored, scaly plaques. Skin examination revealed salmon-colored plaques with "islands of sparing" on the trunk and waxy keratoderma on the palms and soles. Histopathology of the lesion showed alternating orthokeratosis and parakeratosis in vertical and horizontal directions, consistent with a diagnosis of pityriasis rubra pilaris (PRP).

Pityriasis rubra pilaris with eosinophilia in a young patient: a case report.

Introduction And Importance: Pityriasis rubra pilaris is a rare inflammatory papulosquamous disorder which manifests in six clinical subtypes affecting both pediatric and adult populations.

Presentation Of Case: A 14-year-old female presented with multiple itchy scaly lesions on her hands and legs which began as vesicles 9 days after birth. Histopathological examination confirmed the diagnosis of pityriasis rubra pilaris.

Guselkumab - In Psoriasis and Beyond.

Introduction: Guselkumab is an interleukin 23p19 inhibitor, and the first in this group, to be approved by the US Food and Drug Administration for the management of moderate to severe psoriasis. Apart from its utility in psoriasis, there are a number of other dermatologic conditions where guselkumab has demonstrated value.

Objectives: The aim of this narrative review is to describe the utility of guselkumab in psoriasis as well as its implication in off-label dermatologic disorders.
