Differentiating diseases that cause erythematous or papulosquamous rash[edit | edit source]

Disease	Rash Characteristics	Signs and Symptoms	Associated Conditions
Cutaneous T cell lymphoma/Mycosis fungoides^[1]	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, erythematous, eczema-like rash. Plaque phase: Small raised bumps (papules) or hardened lesions on the skin, which may be erythematous. Tumor phase: Tumors form on the skin. Infection secondary to ulcers.	Epidermal atrophy or poikiloderma Generalized itching (pruritus) Pain in the affected area of the skin Insomnia Red (erythematous) patches scattered over the skin of the trunk and the extremities Tumor-like lobulated outgrowths form on the skin in the latter phase of the disease Weight loss Lymphadenopathy Malaise and fatigue Anemia May progress to Sezary syndrome (skin involvement plus hematogenous dissemination)	Sezary syndrome
Pityriasis rosea^[2]	Pink or salmon in color, which may be scaly; referred to as "herald patch" Oval shape Long axis oriented along the cleavage lines Distributed on the trunk and proximal extremities Squamous marginal collarette and a “fir-tree” or “Christmas tree” distribution on posterior trunk Secondary to viral infections Resolves spontaneously after 6-8 weeks	Preceded by a prodrome of: Sore throat Gastrointestinal disturbance Fever Arthralgia	Infection by any of the following:^[3] HHV-6 HHV-7 HHV-8
Pityriasis lichenoides chronica	Recurrent lesions are usually less evenly scattered than in cases of psoriasis Brownish red or orange-brown in color Lesions are capped by a single detachable, opaque, mica-like scale Often leave hypopigmented macules	High fever Malaise Myalgias Paraesthesia Pruritus	Infection by any of the following:^[4] Epstein-Barr virus (EBV) Toxoplasma gondii Human immunodeficiency virus (HIV)
Nummular dermatitis^[5]	Multiple coin-shaped eczematous lesions Commonly affecting the extremities (lower>upper) and trunk May ooze fluid and become dry and crusty	Often appears after a skin injury, such as a burn, abrasion (from friction), or insect bite Lesions commonly relapse after occasional remission or may persist for long periods Pruritus	Associated with: Dry skin Emotional stress Allergens (rubber chemicals, formaldehyde, neomycin, chrome, mercury, and nickel) Staphylococcus infection Seasonal variation Alcohol Drugs Atopy
Secondary syphilis^[6]	Round, coppery, red colored lesions on palms and soles Papules with collarette of scales	Fever Generalized lymphadenopathy Sore throat Patchy hair loss Headache Weight loss Myalgia Fatigue	Associated with: Condylomata lata Corona verinata Positive VDRL test
Bowen’s disease^[7]	Erythematous, small, scaly plaque, which enlarges erratically over time Scale is usually yellow or white and it is easily detachable without any bleeding Well-defined margins	Pruritus Pain Bleeding lesions	Associated with:^[8] Erythroplasia of Queyrat (Bowen's disease of the penis) Squamous cell carcinoma Solar radiation and ultraviolet (UV) exposure Radiotherapy Immunosuppression Arsenic exposure Human papilloma virus (HPV) type 16 Merkel cell polyomavirus Sjögren’s syndrome
Exanthematous pustulosis^[9]	Numerous small, primarily non-follicular, sterile pustules, arising within large areas of edematous erythema	Fever Leukocytosis Intracorneal, subcorneal, and/or intraepidermal pustules with papillary dermal edema containing neutrophils and eosinophils	Associated with:^[10] Antibiotics (penicillins, sulfonamides, tetracyclines) Carbamazepine Calcium channel blockers (Diltiazem) Hydroxychloroquine
Hypertrophic lichen planus^[11]	Classically involves shin and ankles and is characterized by hyperkeratotic plaques and nodules covered by a scale Lesions may transform into hyperkeratotic thickened, elevated, purplish or reddish plaques and nodules	Chronic pruritus Scaling May be asymptomatic	Associated with Hepatitis C virus infection^[12]
Sneddon–Wilkinson disease^[13]	Flaccid pustules that are often generalized and have a tendency to involve the flexural areas Annular configuration	Pruritus May be asymptomatic	Associated with: Monoclonal gammopathy, usually an IgA paraproteinemia^[14] Crohn's disease^[15] Osteomyelitis Adalimumab^[16]
Small plaque parapsoriasis^[17]	Erythematous plaques with fine scaly surface May present with elongated, finger-like patches Symmetrical distribution on the flanks 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	May progress to mycosis fungoides^[18]
Intertrigo^[19]	Red and fleshy looking lesion in skin folds Itching Oozing May be sore	Pruritus Musty odor	Associated with: Infections (Fungal, bacterial, viral) Allergies Diabetes Obesity
Langerhans cell histiocytosis^[20]	Scaling and crusting of scalp	Pathological fractures^[21] Visceromegaly (hepatomegaly, spleenomegaly) Chronic cough Dyspnea^[22] Lymphadenopathy	Associated with: Diabetes insipidus^[23] Pancytopenia
Tinea manuum/pedum/capitis^[24]	Scaling, flaking, and sometimes blistering of the affected areas Hair loss with a black dot on scalp in case of tinea capitis	Pruritus KOH preparation of the lesions confirms fungal infection	Associated with: Diabetes Immunosupression Intimate contact with infected person May lead to asthma exacerbation
Seborrheic dermatitis	Papulosquamous, scaly, flaky, itchy, and red rash found particularly at sebaceous gland-rich areas of the body	Pruritus	Associated with:^[25] AIDS Stress^[26] Fungal infection Fatigue Sleep deprivation Change of season Parkinson's disease Biotin deficiency
