RESUMO
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. CONCLUSIONS: This study confirms the efficacy of patch tests in patients with delayed hypersensitivity reactions to hydroxychloroquine.
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 DE 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. CONCLUSIONES: Este estudio confirma la eficacia de las pruebas epicutáneas en pacientes con reacciones de hipersensibilidad retardada a hidroxicloroquina.

Introduction: Eosinophilic esophagitis (EoE) is a chronic esophageal atopic disease because sensitization to aeroallergens and foods allergens is very common. Objectives: This study is the first work that studies multiple characteristics of EoE in the southeast of Spain to know whether EoE in the patients of this region is similar to that of other regions of Spain in terms of demography, symptoms, and atopic characteristics. Method: It is an observational prospective study of patients diagnosed with EoE at Granada (Spain). We recorded demographic data (age, sex, and personal history of atopy), clinical data (impaction and dysphagia), allergologic data (prick test and specific immunoglobulin E) to foods, aeroallergen, and pan-allergens, and other endoscopichistologic data and comorbidities. Results: The demographic, allergologic, and endoscopic characteristics of patients with EoE in Granada were similar to the rest of Spain, except the higher frequency of sensitization to olive pollen, food allergy, and anaphylaxis reactions. Conclusions: The higher frequency of sensitization to olive pollen and food allergy with severe clinical manifestations (anaphylaxis) in patients with EoE in Granada could have a negative impact on patients quality of life (AU)
