* Premycotic phase: A scaly, red [[rash]] in areas of the [[body]] that usually are not exposed to the sun. This rash does not cause symptoms and may last for months or years.
* Patch phase: Thin, reddened, [[eczema]] -like rash.
* [[Plaque]] phase: Small raised [[Bumps on skin|bumps]] ([[Papule|papules]]) or hardened lesions on the skin, which may be reddened.
* [[Tumor]] phase: Tumors form on the [[skin]]. These tumors may develop [[Ulcer|ulcers]]<nowiki/>and the skin may get infected.

Overview

Differential Diagnosis

Disease Rash Characteristics Signs and Symptoms Associated Conditions Rash Appearance
Cutaneous T cell lymphoma/Mycosis fungoides[3]
  • Premycotic phase: A scaly, red rash in areas of the body that usually are not exposed to the sun. This rash does not cause symptoms and may last for months or years.
  • Patch phase: Thin, reddened, eczema -like rash.
  • Plaque phase: Small raised bumps (papules) or hardened lesions on the skin, which may be reddened.
  • Tumor phase: Tumors form on the skin. These tumors may develop ulcersand the skin may get infected.

Pityriasis rosea[4]
  • Pink or salmon in colour, which may be scaly, termed as "herald patch"
  • Oval in shape
  • Long axis oriented along the clevage lines
  • Distributed on the trunk and proximal extremities
  • Squamous marginal collarette and a “fir-tree” or “Christmas tree” distribution on the posterior trunk
  • Develops after viral infection
  • Resolves spontaneously after 6-8 weeks

Pityriasis lichenoides chronica
  • Recurrent lesions are usually less evenly scattered than psoriasis
  • Brownish red or orange-brown color
  • Lesions are capped by a single detachable opaque mica-like scale
  • Often leave hypopigmented macules

Nummular dermatitis[7]
  • Lesions commonly relapse after occasional remission or may persist for long periods
  • Pruritis

Secondary syphilis[8]
  • Round coppery red color lesions on palms and soles
  • Papules with collarette of scales

Bowen’s disease[9]
  • Erythematous little scaly plaque, which enlarges over time in an erratic manner
  • Scale is usually yellow or white and it is easily detachable without producing any bleeding
  • Well defined margins

Exanthematous pustulosis[11]

Hypertrophic lichen planus[13]
  • Chronic pruritis
  • Scaling
  • May be asymptomatic

Sneddon–Wilkinson disease[15]
  • Flaccid pustules that are often generalized and have a tendency to involve the flexural areas
  • Have an annular configuration

Small plaque parapsoriasis[19]
  • Erythematous plaques which are covered with fine scale.
  • May present with elongated, finger-like patches symmetrically distributed on the flanks, also known as digitate dermatosis
  • Lesions may be asymptomatic
  • May be mildly pruritic
  • May fade or disappear after sun exposure during the summer season, but typically recur during the winter

Intertrigo[21]
  • Red and fleshy looking lesion in skin folds
  • Itching
  • oozing
  • May be sore

Langerhans cell histiocytosis[22]
  • Scaling and crusting of the scalp
