[1] The skin rash of tinea versicolor (pityriasis versicolor) is also due to infection by this fungus.
A skin biopsy can be performed to test for EAC; tests should be performed to rule out other possible diseases such as: pityriasis rosea, tinea corporis, psoriasis, nummular eczema, atopic dermatitis, drug reaction, erythema migrans and other rashes.
