Psoriasis
pink to SALMON OVAL shaped patches thin TRAILING CENTRAL SCALE sparsely scattered over the central trunk CHEST and ABDOMEN
Pityriasis Rosea
Red to pink “target-like” or “TARGETOID” macules on the PALMS and SOLES non-descript pink macular and MORBILIFORM ON TRUNK MUCOSAL EROSIONS (oral, ocular, nasal and genital) with the major variant
Erythema Multiforme
Asymptomatic ANNULAR PATCHES, CENTRAL CLEARING, WITHOUT SCALE DORSAL HANDS and FEET
Granuloma Annulare
Pink to orange to hyperpigmented or hypo pigmented oval and annular patches on the central chest and back, with THIN SUPERFICIAL SCALE KOH positive scale
Tinea Versicolor
Pink pruritic papules, some scale and some small linear vesicles and burrows, often in the skin folds especially the finger web spaces Never in mouth
Scabies
Mycosis Fungoides CTCL
Red to violaceous patches linear to oval and annular, with mild elevation and scale many variations MALIGNANCY
Subacute lupus
ANNULAR and ARCUATE patches, may coalesce, upper chest and back
Drug Rashes
Urticarial → small to large wheals which migrate form arcuate shapes and coalesce Morbilliform → measle-like (morbilliform) distribution of pink to red round patches Blistering and Necrolysis → ominous → initial erythroderma, bullae formation and sloughing of dead or necrotic skin, indicates “toxic epidermal necrolysis” or TEN which has a high mortality rate.
Tinea aka Dermatophytosis
* PINK ANNULAR patches with an inflamed border and CENTRAL CLEARING with LEADING SCALE

Syphilis
Urticarial → small to large wheals which migrate form arcuate shapes and coalesce Morbilliform → measle-like (morbilliform) distribution of pink to red round patches Blistering and Necrolysis → ominous → initial erythroderma, bullae formation and sloughing of dead or necrotic skin, indicates “toxic epidermal necrolysis” or TEN which has a high mortality rate.
