Differentiating Psoriasis from other Diseases

• Psoriasis must be differentiated from other diseases causing papulosquamous or erythematosquamous rash especially when the psoriatic lesions are localized in particular sites for example, palms, soles, scalp, body folds, penis and nails.
• The differentials include:
  • Cutaneous T cell lymphoma/mycosis fungoides
  • Pityriasis rosea
  • Pityriasis rubra pilaris
  • Pityriasis lichenoides chronica
  • Nummular dermatitis
  • Secondary syphilis
  • Bowen’s disease
  • Exanthematous pustulosis
  • Hypertrophic lichen planus
  • Sneddon–Wilkinson disease
  • Small plaque parapsoriasis
  • Intertrigo
  • Langerhans cell histiocytosis
  • Dyshidrotic dermatitis
  • Tinea manuum/pedum/capitis
  • Seborrheic dermatitis
