While patch-stage MF can mimic eczema, it is distinguished by its resistance to standard therapy, occurrence in non-flexural areas (buttocks), and bizarre, arcuate shapes.
PRP is characterized by a distinctive salmon-pink color, prominent follicular papules, and islands of skin sparing, features not typical of MF.
Psoriatic plaques have a much thicker, silvery scale and a preference for extensor surfaces, whereas MF plaques are often thinner, more atrophic, and less scaly.
