- Abstract: A 20-year-old female patient presented with erythema and pustules on both hands accompanied by itching for 1 month. Skin examination showed patchy erythema on the thenar eminence and little finger of each hand, covered with yellow crusts; on the basis of erythema, soybean- to broad bean-sized pustules were observed, with turbid pustular fluids and flaccid pustular walls, but without rupture. Fungal microscopy of skin scales revealed the presence of hyphae. The hedgehog spines and the patient's skin scales were both subjected to fungal culture, and microscopy showed septate hyphae in both colonies; the sequencing of the two colony samples mentioned above both indicated Trichophyton erinacei, and the homology was as high as 99.8%. Finally, the patient was diagnosed with Trichophyton erinacei-induced tinea incognito. The patient′s symptoms subsided after 2-week treatment with itraconazole and naftifine hydrochloride.
