Rôle du laboratoire dans le diagnostic étiologique d'une lésion cutanée d'origine infectieuse au retour d'une zone tropicale

Skin lesions of infectious diseases after a tropical travel is a very large thematic. The majority of these infections may contract in tropical areas but also in temperate countries. Only major or current infections are covered in this article. For bacteriology: scratching superinfection, borreliosis-rickettsiosis; for virology: dengue chikungunya and zika; for mycology: pityriasis versicolor, dermatophytiosis, moths and candidiasis; for parasitology: larbish, schistosomiasis, leishmaniasis and for entomology: chip, myiasis, scabies, bed bugs, mosquitoes, ticks, fleas. When biology is possible, a collaboration between “biologist and physician” is paramount in order to target the relevant infections and examinations.
