Abstract

Diethylthiourea, like other thioureas, is often used by the rubber industry and in the manufacture of neoprene. We present a patient who suffered allergic contact dermatitis to diethylthiourea in a neoprene wader and who required admission to hospital and systemic treatment. We review the literature on allergy to diethylthiourea. Thioureas are not included in the standard GEIDAC (Spanish Contact Dermatitis Research Group) battery of patch tests. In these cases, it is necessary to use a special battery of rubber allergens, which includes thiourea compounds, for diagnosis of the disease and to ensure that cases of contact allergic dermatitis to thioureas do not go undiagnosed.

Key words:
allergy
contact dermatitis
rubber
neoprene
diethylthiourea
patch tests
Resumen

La dietiltiourea, como otros compuestos del grupo de las tioureas, se usa frecuentemente en la industria de las gomas y en la fabricación de neopreno. Presentamos un caso de dermatitis alérgica de contacto (DAC) por dietiltiourea en un traje de pesca de neopreno que precisó ingreso hospitalario y tratamiento sistémico y revisamos la literatura publicada de alergia a dietiltiourea. Las tioureas no están incluidas en la batería estándar del GEIDAC (Grupo Español de Investigación en Dermatitis Alérgica de Contacto). En estos casos debe utilizarse una batería especial de gomas, que contenga compuestos de tiourea, para llegar al diagnóstico etiológico de la enfermedad y evitar que los casos de DAC por tioureas queden sin diagnosticar.

Palabras clave:
alergia
dermatitis de contacto
gomas
