          Abstract

          Resumen Introducción: El eritema exudativo multiforme es una reacción de hipersensibilidad retardada poco frecuente asociada con medicamentos. Las manifestaciones provocadas por hidroxicloroquina son excepcionales; sin embargo, debido al incremento de su prescripción, por la reciente pandemia de SARS-CoV-2, las reacciones adversas se han exacerbado. Reporte del caso: Paciente femenina de 60 años, que acudió al servicio de Urgencias por un cuadro de exantema eritematoso de una semana de evolución, con afectación hacia el tronco, la cara y las palmas de las manos. Los estudios de laboratorio informaron: leucocitosis con neutrofilia y linfopenia, sin eosinofilia ni alteración de las enzimas hepáticas. Las lesiones continuaron descendiendo hacia las extremidades, con posterior descamación. Se le indicó prednisona 15 mg/24 h durante tres días, con disminución a 10 mg/24 h, hasta su nueva valoración, además de antihistamínicos. Dos días posteriores aparecieron nuevas lesiones maculares en la zona preesternal y en la mucosa oral. Los estudios de laboratorio de control no mostraron alteraciones. La biopsia cutánea informó: dermatitis de interfase vacuolar con espongiosis y paraqueratosis, compatible con eritema multiforme. Se llevaron a cabo pruebas epicutáneas con meloxicam e hidroxicloroquina al 30% en agua y vaselina, ocluidos dos días e interpretados a las 48 y 96 horas, con resultado positivo para esta última. Se estableció el diagnóstico de eritema exudativo multiforme por hidroxicloroquina. Conclusión: Este estudio confirma la eficacia de las pruebas epicutáneas en pacientes con reacciones de hipersensibilidad retardada a hidroxicloroquina.

          Abstract Introduction: Multiform exudative erythema is a rare delayed hypersensitivity reaction associated with medications. The manifestations caused by hydroxychloroquine are exceptional; however, due to the increase in its prescription due to the recent SARS-CoV-2 pandemic, adverse reactions have been exacerbated. Case report: A 60-year-old female patient, who attended the Emergency Department for a picture of erythematous rash of one week of evolution, with involvement of the trunk, face and palms of the hands. Laboratory studies reported: leukocytosis with neutrophilia and lymphopenia, without eosinophilia or abnormal liver enzymes. The lesions continued to descend towards her extremities, with subsequent desquamation. She was prescribed prednisone 15 mg/24 h for three days, tapering to 10 mg/24 h, until her new assessment, in addition to antihistamines. Two days later, new macular lesions appeared in the presternal area and on the oral mucosa. Control laboratory studies did not show alterations. Skin biopsy reported: vacuolar interface dermatitis with spongiosis and parakeratosis, compatible with erythema multiforme. Epicutaneous tests were carried out with meloxicam and 30% hydroxychloroquine in water and vaseline, occluded for two days and interpreted at 48 and 96 hours, with a positive result for the latter. The diagnosis of multiform exudative erythema due to hydroxychloroquine was established. Conclusion: This study confirms the efficacy of patch tests in patients with delayed hypersensitivity reactions to hydroxychloroquine.

          Erythema Multiforme and COVID-19: What Do We Know?

          Background: Erythema multiforme (EM) is an acute cutaneous eruption often associated with infections and more rarely with drugs. This review aimed to evaluate the association between erythema multiforme and coronavirus disease 2019 (COVID-19). Methods: A systematic search of PubMed/MEDLINE, Scimago Scopus, and ISI/Web of Science was performed. Original articles, case series, or case reports were evaluated and selected. Results: Fourteen articles were selected, describing a total of 70 patients. EM is a cutaneous eruption rarely occurring in COVID-19 and is, in most cases, associated with a hypersensitivity reaction to the virus. In these cases, EM seems to affect patients younger than 30 years or older than 55 years. Infrequently, some drugs used in the management of COVID-19 may induce EM, especially hydroxychloroquine. The three groups of patients seem to have different clinical characteristics and courses. Conclusions: From these data, it is possible to preliminarily propose that EM or EM-like eruptions linked to COVID-19 might be divided into three types: the virus-related juvenile type (affecting patients <30-year-old), the virus-related older type (affecting patients >55 years), and the drug-induced type. The occurrence of a skin rash does not seem to be related to the severity and clinical course of COVID-19.

              The safety profile of hydroxychloroquine: major cutaneous and extracutaneous adverse events.

              Hydroxychloroquine is an established therapy for several rheumatological disorders, and very recently it has been proposed as a possible treatment for the new coronavirus disease 2019 even if recent randomised trials did not prove any benefit. Notably, hydroxychloroquine has been associated with a heterogeneous range of cutaneous and extra-cutaneous adverse events. We carried out a narrative review of the literature up to November 1st, 2020, related to the safety of hydroxychloroquine. In particular, cutaneous and extra-cutaneous adverse events associated with hydroxychloroquine were reviewed. The following databases were consulted: PubMed, Embase, Google Scholar and ResearchGate. The research of articles was conducted by using the following search terms: ''hydroxychloroquine," ''adverse event/effect,'' "cutaneous", "skin", "cardiotoxicity", "retinopathy", gastrointestinal and neurological toxicity". The main indication for which hydroxychloroquine was used in the reports was an immune mediated disorder. Adverse events were described mostly in females over 50 years of age. The most common cutaneous adverse effect was maculopapular and erythematous rash occurring within 4 weeks of initiating hydroxychloroquine and disappearing within few weeks of discontinuation. Gastrointestinal symptoms and headache were the most frequent extracutaneous manifestations. Rarer cutaneous manifestations include hyperpigmentation, psoriasiform dermatitis, photodermatitis, stomatitis, melanonychia and hair loss. More severe conditions were acute generalised exanthematous pustulosis, drug rash with eosinophilia and systemic symptoms, Stevens-Johnson syndrome/toxic epidermal necrolysis, and among extra-cutaneous adverse events cardiotoxicity and retinopathy. Since hydroxychloroquine is widely prescribed in rheumatology, it is important for rheumatologists to be familiar with its safety profile.
