Erythrodermic psoriasis is a rare and potentially fatal skin condition. We present the case of a 68-year-old woman, with no prior dermatologic history, who was treated with steroid injection for an insect bite one month prior to presentation and subsequently developed a diffuse erythematous rash. She presented to a military medical center in shock, with weeping, coalesced plaques covering the majority of her skin. Skin biopsies revealed pustular psoriasis, and treatment with infliximab was initiated for erythrodermic psoriasis. After six weeks and three infliximab infusions, the cutaneous lesions had nearly completely resolved.

Erythrodermic psoriasis (EP) is a life-threatening variant of psoriasis. In this study, we contrasted the vascular endothelial cells (ECs) in EP lesions against those in psoriasis vulgaris and healthy controls. Utilizing single-cell RNA sequencing, immunofluorescence, and flow cytometry on human and mouse samples, we observed a marked increase and activation of EP ECs, which upregulated genes relative to angiogenesis, leukocyte adhesion and antigen presentation.

Erythrodermic psoriasis (EP) is a rare and challenging-to-diagnose severe form of psoriasis. Its presentation can have similarities with other inflammatory skin conditions, complicating subsequent management. We present a case of a 76-year-old woman with EP who presented with fever, tachycardia, leg swelling with pain and redness, and reduced consciousness.

Psoriasis (PsO) is a chronic, systemic, and autoimmune dermatologic condition characterized by dry, scaly, and erythematous plaques on the skin. PsO can present in various forms, including guttate (small, round lesions commonly over the upper trunk and extremities that can be raised and scaly), inverse (smooth plaques of inflamed skin within skin folds of the groin, buttock, and breasts), pustular (white painful pustules within red inflamed blotches widespread over the body), and erythrodermic (red rash present over most of the body). Individuals with PsO can present differently, with unique symptoms and patterns on the skin.

Background: Chronic erythroderma is a potentially life-threatening condition that can be caused by various diseases, but approximately 30% of cases remain idiopathic, often with insufficient treatment options.
Objective: We sought to establish a molecular disease map of chronic idiopathic erythroderma (CIE).
Methods: We performed single-cell RNA sequencing combined with T-cell receptor sequencing of blood and skin from 5 patients with CIE and compared results with 8 cases of erythrodermic cutaneous T-cell lymphoma (eCTCL), 15 cases of moderate to severe atopic dermatitis, 10 cases of psoriasis, and 20 healthy control individuals.

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.
