Parakeratotic foci alternating with orthokeratosis in both vertical and horizontal directions. Original cornified layer still preserved. Slight epidermal hyperplasia with thick suprapapillary plates. These findings are those of pityriasis rubra pilaris.

A checkerboard pattern in the stratum corneum with preservation of the stratum granulosum drives me to agree with Romualdo's diagnosis of pityriasis rubra pilaris. I would feel more comfortable if shoulder parakeratosis at the edges of follicular ostia and keratotic follicular plugs were present in the sample.

PRP in absence of clinical hx or other images to the contrary. Checkerboard parakeratosis paired with minimal perivascular chronic inflammation, psoriasiform wide rete pegs, and hypergranulosis.
