Secondary reactions to fungi (trichophytes, epidermophytide, microsporide) or other infectious agents in hyperergic immune states.
Dermatophyte infection is a hyperergic immune condition that leads to antigen resorption and finally to an antigen-antibody reaction. From an immunological point of view, this is a type IV reaction. The Id reaction usually occurs far away from the focus.
Dyshidrosiform, nodular or multiform erythema, mostly on the extremities.
A special form is the Lichen trichophyticus: It is a symmetrical, disseminated sowing of follicular papules located on the stem.
Testing of the immune status is not recommended.
With effective treatment of causative mycosis or other infectious disease very good.
