Dermatology Pathways

ABCDE assessment, 2WW referral, and Breslow thickness staging for melanoma

Eron class severity grading, IV vs oral antibiotic decision, and marking for monitoring

PASI/DLQI-based severity classification and topical to biologic treatment escalation for plaque psoriasis

IGA-based severity assessment and NICE step-up treatment ladder for atopic eczema in adults and children

Acute vs chronic urticaria classification, anaphylaxis exclusion, and antihistamine step-up management

Severity grading and NICE-aligned topical to systemic to isotretinoin treatment escalation

BCC vs SCC recognition, risk stratification, 2WW referral criteria, and treatment options

Severe drug reaction — stop offending drug, ITU/burns unit, supportive care, SCORTEN prognosis, IVIG / ciclosporin in selected.

Generalised erythema + scaling >90% body surface — recognise life-threatening complications, identify cause, supportive care.

Distinguish (clinical + immunofluorescence) — pemphigus vulgaris (intra-epidermal, mucosal involvement) vs bullous pemphigoid (sub-epidermal, elderly), corticosteroid + steroid-sparing.

HSV superinfection of eczematous skin — punched-out vesicles, monomorphic, fever, systemic illness; aciclovir IV.

Range of drug eruptions — recognise red flag (DRESS, SJS/TEN, AGEP), stop drug, supportive care, organ monitoring in DRESS.

Hurley staging, lifestyle (smoking, weight), antibiotics, biologics, surgical excision for severe.

Diagnosis, autoimmune screen, narrowband UVB, topical / oral therapies, JAK inhibitors emerging, psychological support.

Distinguish patterns (alopecia areata, androgenetic, telogen effluvium, scarring), exclude reversible causes, biologics for severe AA.

Subtype-driven (erythematotelangiectatic, papulopustular, phymatous, ocular), trigger avoidance, topical + systemic therapies.

Distinguish primary (focal — axillae, palms, soles) from secondary (medical cause). Topical → iontophoresis → botox → systemic → surgery.

Differentiate idiopathic (PMLE, solar urticaria), drug-induced, autoimmune (lupus), genetic; sun avoidance + targeted therapy.

Distinguish ACLE (malar) / SCLE (annular) / CCLE (discoid) — biopsy + autoimmune workup, hydroxychloroquine + sun protection.
