2 % agarose gel showing the specimen control size (SCS) ladder HPyV6 DNA-PCR and SCS ladder for keratoacanthoma (KA), results HPyV6 DNA-PCR: a reveals adequate DNA quality of KA in order to proceed with HPyV6 testing. b HPyV6 DNA PCR results of selected KA, showing amplification of the 123 bp fragment of the VP1 gene (123 bp) while using the primers according to Schowalter et al. [12] with the 123 pb positive controle. c Summary of the HPyV6-DNA PCR results on (KA), trichoblastoma (TB), basal cell carcinoma (BCC) and squamous cell carcinoma (SCC)
