Preferred Label : Trombiculosis;
ICD-11 definition : A pruritic, papular or papulovesicular skin eruption due to bites by the larvae of
trombiculid mites (harvest mites or chiggers). The larva injects digestive enzymes
into the skin in order to facilitate feeding from host tissue. The cutaneous response
is considered to be due both to an irritant effect of the larval saliva and an acquired
hypersensitivity to salivary antigens. Areas favoured by the mites are those where
the skin is thin (genital region, axillae, limb flexures).;
ICD-11 synonym : Harvest mite infestation; scrub itch; trombiculiasis; trombiculid mite infestation; trombidiosis; trombicula infestation; harvest itch; chigger bites; chigger infestation;
