According to Khosravi et al. The clinical presentations vary widely from noninflammatory, scaling plaques to inflammatory pustules. Dermatophytes are classified according to body region. Tinea These variations depend on the infecting organism and host corporis is defined as dermatophytosis of glabrous parts of immune responses.
Geophilic and zoophilic species are more body, face, neck, and limbs. Any of the dermatophyte apt to cause inflammatory lesions that can range from species are capable of causing tinea corporis. We report a patient who suffered skin lesion on her neck. Based on clinical and histopathological findings, it was sug- gested that she was involved with DLE. For this reason she was treated with local and systemic corticosteroids and hydroxychloroquine sulfate.
The inflammatory reaction was decreased for a few days but the plaques and scaling relapsed and the lesion became remarkable with some new vesicles; thus she was examined for dermatophyte infection. Laboratory examination confirmed T.
It seems that dermatophyte infection was transmitted from a hospitalized patient suffering from tinea corporis. In acute dermatophytosis due to severe inflamma- tory reaction a little fungal element can be found into the lesion, for this reason in PAS staining we could not show the dermatophyte conidia or hyphae.
Corticosteroid and hydro- xychloroquine therapy leads to local and systemic immune system deficiency and the clinical signs could be changed to Figure 3 Terminal and intercalary chlamydoconidia of moderate or chronic; in this condition dermatophytes can T.
