Summary The effectiveness of a simple PCR protocol performed on paraffin‐embedded tissues, obtained from histopathologically and culturally diagnosed cases of dermatophytic pseudomycetoma DPM was tested. The specimens were investigated using previously described primers (DH1L and DH1R) targeting the 18S rDNA gene and amplifying a 183‐bp fragment. Microsporum canis was identified from all samples. The PCR protocol described in the present work demonstrated a 100% concordant result comparing the molecular characterisation with phenotypic characterisation of dermatophytes. Molecular biology could represent a valid identification tool in dermatophytic deep infections, when diagnosis cannot be achieved by cultural methods.
