ABSTRACT

El eritema flagelado es una erupción cutánea poco frecuente con múltiples causas, dentro de las cuales se encuentra la ingesta de hongos shiitake crudos o semicrudos. Se postula que es secundario a una reacción de hipersensibilidad Th-1 producida por el lentinan, un polisacárido termolábil de la pared celular del hongo. En años recientes ha aumentado su incidencia en el mundo occidental debido a la creciente popularidad de la comida asiática, en la que los hongos shiitake son un ingrediente muy utilizado. El cuadro clínico se caracteriza por la aparición de lesiones eritematosas lineales pruriginosas principalmente en tronco y extremidades, de curso autolimitado. El diagnóstico es principalmente clínico, basado en el antecedente de ingesta reciente de hongos shiitake y el rash característico y el tratamiento es sintomático con antihistamínicos y corticoides tópicos u orales. A continuación, presentamos un caso de eritema flagelado en una mujer joven, secundario a ingesta de hongos shiitake, que se resolvió completamente en 2 semanas.


Flagellate erythema is a rare skin eruption with many causes, including the ingestion of raw or undercooked shiitake mushrooms. It is thought to be a Th-1 hypersensitivity reaction produced by lentinan, a thermolabile polysaccharide found in the cell wall of the mushroom. In recent years, there has been an increase in the number of cases due to the growing popularity of Asian cuisine, in which shiitake mushrooms are a central ingredient. The clinical presentation is characterized by the appearance of linear, erythematous, pruritic lesions mostly on the trunk and extremities, of self-limited course. Diagnosis is mainly clinical, based on the history of recent shiitake mushroom ingestion and the characteristic rash, and treatment is symptomatic, with antihistamines and topical or systemic steroids. In this report, we present a case of flagellate erythema in a young woman, that appeared after the ingestion of shiitake mushrooms, and resolved completely after 2 weeks.
