||Skin reactions induced by experimental exposure to setae from larvae of the northern pine processionary moth (Thaumetopoea pinivora)

||This study aimed to evaluate the skin reactions following exposure to setae from larvae of the northern pine processionary moth (Thaumetopoea pinivora, TP). A drop of setae suspension was applied on the forearm of six volunteers. The local skin reactions were studied by microscopy and skin perfusion using laser Doppler (LD) scanning. Setae penetrated into the skin, and LD scanning showed a marked increase in blood perfusion in all subjects. In two subjects, having a history of severe symptoms, microscopic vacuoles developed around setae, followed by desquamation and severe symptoms. In the remaining individuals with only light symptoms during previous exposure, there were only mild reactions that disappeared within three weeks. No immunoglobulin (Ig) E or IgG4 antibodies to larval antigens were found in any of the volunteers.
