I wouldn't say this was classical PRP histology, but there is a hint of alternating ortho- and para-keratosis in the vertical, but not the horizontal plane, at least in the sections we are shown.  If it is PRP, in a patient of this age the classical juvenile presentation should have spontaneously abated by now.  If this is PRP, and I think it is going to be more a clinical than histological diagnosis, then it must be the atypical, juvenile onset variety.
