Porokeratoma is a rare, relatively newly described and still unclear entity. Here, we describe the case of a 52-year-old male patient who presented with four well-defined, verrucous and hyperkeratotic lesions. Microscopically, one of the lesions showed acanthopapillomatosis overlying compact orthokeratosis. Prominent broad and confluent cornoid lamellae were present, with no granular layer and some dyskeratotic keratinocytes. PCR sequencing and in situ hybridization revealed the presence of human papillomavirus (HPV) type 16 in the lesion. The association of porokeratoma and HPV infection has not previously been reported.
