A mycid or dermatophytid is understood to mean a hyperergic hematogenous scattering reaction of the skin in a mycosis , e.g. B. athlete's foot . Remote arises from the actual skin fungus stove, usually occur on the hands as hypersensitivity reaction to dermatophytes - antigen a maculopapulöser, partly vesicular rash or a thickened, coarsened skin ( lichenification ). There is excruciating itching in these areas. No fungi can be detected in the Mykid. A recurrent course is possible. It is an often underdiagnosed disease.

There are only sporadic reports of this disease in the literature. This may be due to the fact that mykids are only diagnosed occasionally in practice.

therapy

Treatment of the primary focus, e.g. B. athlete's foot and treatment of the mycid with ointments containing antifungal-glucocorticosteroid combinations or terbinafine. Initially, the itching may intensify during therapy. A single treatment with triamcinolone can also lead to the healing of the mycid before the actual skin fungal focus heals.

Differential diagnosis

Dyshidrosis, dyshidrotic atopic eczema or dyshidrotic, also hematogenous contact eczema. Erythema exudativum multiforme.
