[Dermatitis and arthropods (Anobium punctatum and Cimex lectularius) in summer: three case reports]. / Dermatites et arthropodes (Anobium punctatum et Cimex lectularius) en période estivale : à propos de trois cas.

ABSTRACT

We report three cases of pruritic dermatitis with erythematous maculopapules, having a similar clinical presentation, in summer, and caused by two different arthropods. In wandering diagnosis since sometimes several months, patients have made entomologic investigations in their home. Two of three samples, have shown an infestation by Anobium punctatum, the common furniture beetle, a xylophagous beetle (usually harmless for human). It may be parasited by Pyemotes ventricosus, a mite known since the 19th century to cause this type of hurt. The third sample contained Cimex lectularius or bedbug, haematophagous insect, classically looked for in endemic zone.
