Brote de leishmaniasis cutánea en el municipio de Fuenlabrada / Outbreak of Cutaneous Leishmaniasis in Fuenlabrada, Madrid

Introducción: La leishmaniasis, infección endémica en España, está causada por protozoos del género Leishmania. Durante los años 2010-2012 hubo un brote de leishmaniasis cutánea y visceral en Fuenlabrada, Madrid. Objetivos: Describir los casos de leishmaniasis cutánea (LC) diagnosticados durante 17 meses en el Servicio de Dermatología del Hospital de Fuenlabrada. Material y métodos: Estudiamos variables epidemiológicas, clínicas, histológicas, microbiológicas y terapéuticas de cada caso. Resultados: Se recogieron 149 pacientes. Encontramos una incidencia similar en varones que en mujeres, la edad más frecuente fue entre 46-60 años. El tiempo de evolución presentaba un pico de máxima frecuencia entre los 2 y 6 meses. La forma clínica más habitual fue la de pápulas y placas eritematosas sin costra (52%). En el 57% de los casos las lesiones eran múltiples. La localización más común fue en áreas fotoexpuestas. El estudio histológico mostró en el 67% de los pacientes una dermatitis granulomatosa no necrotizante sin parásitos con tinciones habituales. La reacción en cadena de la polimerasa (PCR) para Leishmania confirmó el diagnóstico en el 98% de los casos. En los demás el estudio histológico de la piel identificó cuerpos de leishmanias. Los antimoniales pentavalentes intralesionales fueron los fármacos más empleados (76%), con resultado satisfactorio. Conclusiones: Presentamos una serie amplia de casos de LC en el contexto de un brote. La forma más habitual fue la aparición de múltiples pápulas, y la forma histológica la dermatitis granulomatosa no necrotizante, en la que no se observaron leishmanias. La PCR en piel fue la prueba más importante para alcanzar el diagnóstico (AU)

Introduction: Leishmaniasis, an endemic infection in Spain, is caused by protozoan parasites of the Leishmania genus. Between 2010 and 2012, there was an outbreak of cutaneous and visceral leishmaniasis in Fuenlabrada, Madrid. Objectives: To describe the cases of cutaneous leishmaniasis diagnosed over a 17-month period at the dermatology department of Hospital de Fuenlabrada. Material and methods: We analyzed the epidemiological, clinical, histological, and microbiological features of each case and also evaluated the treatments administered and outcomes. Results: We studied 149 cases. The incidence of cutaneous leishmaniasis showed a peak in the age range between 46 and 60 years and was similar in men and women. At the time of consultation, the lesions had been present for between 2 and 6 months in the majority of patients. The most common clinical presentation was with erythematous plaques and papules without crusts (52% of cases). Lesions were most often located in sun-exposed areas and were multiple in 57% of patients. In 67% of cases, the histological study showed non-necrotizing granulomatous dermatitis with no evidence of parasites using conventional staining methods. Diagnosis was confirmed by polymerase chain reaction (PCR) in 98% of patients. In the remaining cases, the histological study revealed Leishman-Donovan bodies in the skin. Intralesional pentavalent antimonials were the most commonly used drugs (76% of cases) and produced satisfactory results. Conclusions: We have presented a large series of cases of cutaneous leishmaniasis diagnosed in the context of an outbreak. Multiple papules were the most common clinical presentation, with histology that showed non-necrotizing granulomatous dermatitis with no evidence of parasites. PCR of skin samples was the test that most frequently provided the diagnosis (AU)

Eosinophilic, polymorphic and pruritic eruption associated with radiotherapy (EPPER) in two patients with breast tumour.

Eosinophilic polymorphic and pruritic eruption associated with radiotherapy (EPPER) is a rare entity that appears in oncological patients after radiotherapy. We describe two patients with breast tumour who presented with EPPER in a different area from the one that had been irradiated. One of them needed different types of treatment, topical and systemic corticosteroids, antihistamines and narrowband ultraviolet B. The other one responded to the application of topical corticosteroids. We suggested that this eruption could be more frequent than has been reported.
