Dermatology for NEET-PG

Why Dermatology matters in NEET-PG

Dermatology is the most image-dependent subject in the paper. A single clinical photograph of a scaly plaque, tense bulla or hypopigmented anaesthetic patch can test psoriasis, a bullous disorder or leprosy in one glance, and candidates who have learnt lesions visually answer in seconds while others guess. The subject is also strongly integrated: drug reactions link to pharmacology, bullous disease to immunopathology, cutaneous infections to microbiology, and psoriasis and pemphigus to medicine itself, so marks earned here are reinforced elsewhere. Finally, the Indian flavour is real — steroid-modified tinea, leprosy, scabies, tuberculosis, syphilis and tropical leg ulcers are regular exam territory precisely because they are regular Indian outpatient territory. It is a small subject with a high return per hour invested.

High-yield topics

• Psoriasis: morphology, Auspitz and Koebner signs, nail and scalp disease, guttate and pustular variants, methotrexate and the biologics ladder.
• Lichen planus: the six Ps, Wickham striae, oral and nail involvement, drug-induced and hepatitis C associations.
• Eczema and dermatitis classification: atopic, contact (including parthenium), seborrhoeic, nummular and stasis dermatitis; patch testing.
• Urticaria and angioedema: acute versus chronic, physical urticarias, antihistamine up-titration, omalizumab, hereditary angioedema red flags.
• Cutaneous adverse drug reactions: fixed drug eruption, DRESS, acute generalised exanthematous pustulosis and the Stevens-Johnson syndrome-toxic epidermal necrolysis spectrum with SCORTEN.
• Bullous disorders: pemphigus vulgaris versus bullous pemphigoid — site of split, Nikolsky sign, direct immunofluorescence patterns and first-line therapy.
• Pigmentary disorders: vitiligo (segmental versus non-segmental, phototherapy, surgery) and melasma (epidermal versus dermal, triple combination therapy).
• Acne vulgaris and rosacea: grading, topical retinoids and benzoyl peroxide, isotretinoin rules, rosacea phenotypes and steroid-damaged face.
• Alopecia: scarring versus non-scarring, androgenetic alopecia, alopecia areata, telogen effluvium.
• Infections: dermatophytosis and tinea including tinea incognito, candidiasis, scabies, cutaneous tuberculosis, cutaneous syphilis and viral exanthems.
• Leprosy for the dermatologist: Ridley-Jopling spectrum, hypopigmented patch differentials, histoid and pure neuritic disease.
• Photodermatoses: polymorphic light eruption, porphyria cutanea tarda, xeroderma pigmentosum; phototoxic versus photoallergic reactions.
• Leg ulcers: venous, arterial and neuropathic types, ankle-brachial pressure index before compression.
• Dermatological emergencies: erythroderma, necrotising fasciitis, eczema herpeticum, generalised pustular psoriasis, staphylococcal scalded skin syndrome.
• Basic procedures and tools: cryotherapy indications and complications, dermoscopy patterns.

How to study Dermatology for NEET-PG

Study dermatology morphology-first: before memorising treatment, learn to describe a lesion — macule, papule, vesicle, bulla, pustule, plaque, wheal, atrophy, scale, crust — because the exam gives you the description or the photograph and expects the diagnosis from it. For every condition build the same five-point frame: classical morphology and site, the named eponymous sign if any, the confirming investigation, first-line treatment and one classic complication. Learn in contrasting pairs — pemphigus versus pemphigoid, tinea versus psoriasis, scabies versus pediculosis, viral versus drug exanthem — since NEET-PG tests discrimination more than recall. Give the Indian-tropical block extra weight: tinea and its steroid-modified forms, scabies, leprosy reactions, cutaneous tuberculosis, syphilis and Hansen-related nerve signs appear disproportionately relative to Western curricula. Finally, look at pictures deliberately: an atlas or a question bank's image library, a fixed number of photographs daily, until recognition is reflexive.

Revision strategy

Condense the subject early into one set of comparison notes — a page per disease family with morphology, sign, investigation and treatment — and revise only from that in the final months. Run a weekly image drill: fifteen to twenty clinical photographs, self-tested, mixed across papulosquamous, vesiculobullous, infective and pigmentary disease. Keep a running list of eponymous signs and named phenomena (Auspitz, Koebner, Wickham, Nikolsky, Darier, Hertoghe) and glance at it every few days, as these are pure marks. Revisit drug reaction patterns and the immunofluorescence maps of bullous disease close to the exam, since they are precise-recall territory. In the last week, revise your contrast pairs and emergencies first — they are the highest yield per minute in the entire subject.

Preparation with PrepElephant

The PrepElephant app covers dermatology through topic-wise previous-year questions, a structured question bank with image-based items, and grand-test-style mocks, with error logs that keep your weak disease families in rotation. These free topic pages — from psoriasis to cryotherapy basics — condense each condition into the exact frame the exam uses. We do not promise shortcuts; we promise accurate, exam-pattern practice.
