Erythrodermic Psoriasis: A Case Report Highlighting Clinical Features and Management

Abstract

Background: Erythrodermic psoriasis (EP) is a rare and severe variant of psoriasis that presents as widespread erythema, scaling, and systemic complications such as fever, dehydration, and electrolyte imbalances. It requires urgent medical attention due to the risk of life-threatening complications, including sepsis and multi-organ failure. The condition can arise de novo or as an exacerbation of pre-existing psoriasis, often triggered by medication withdrawal, infections, or systemic inflammation. Case Presentation: We report the case of a 31-year-old male who presented with generalized erythematous, scaly rashes affecting almost his entire body, accompanied by fever and signs of mild malnutrition. His history revealed multiple untreated episodes of similar symptoms over the past six years. Clinical examination confirmed severe erythrodermic psoriasis with acute-on-chronic plaque progression. Initial management with topical emollients failed to provide relief, necessitating a comprehensive treatment regimen consisting of cyclosporine, methotrexate, apremilast, and a macrolide antibiotic (roxithromycin). The patient showed significant improvement within six days, with reduced scaling, erythema, and no reported adverse effects.

Discussion: Erythrodermic psoriasis poses a unique therapeutic challenge, as first-line treatments such as topical corticosteroids and moisturizers often provide inadequate relief. Systemic therapies, including immunosuppressants (methotrexate, cyclosporine) and newer targeted treatments like apremilast, play a crucial role in disease management. This case aligns with previous reports emphasizing the importance of early diagnosis, aggressive treatment, and a multidisciplinary approach to prevent life-threatening complications. Long-term disease control requires patient education, adherence to treatment, and lifestyle modifications to reduce the risk of recurrence.

Conclusion: This case highlights the importance of early intervention, individualized treatment strategies, and continuous monitoring in managing erythrodermic psoriasis. While systemic therapies have shown effectiveness, there remains a need for further research into biologics and precision medicine to improve long-term outcomes. By integrating timely diagnosis, personalized treatment plans, and patient-centered care, clinicians can significantly enhance the quality of life for individuals affected by this debilitating condition.
