Dermatology for NEET PG 2026

Dermatology in NEET PG 2026 tests your ability to translate a clinical vignette — rash morphology, patient demographics, histopathology, immunofluorescence pattern, or smear finding — into a precise diagnosis or management decision. It does not reward rote memorisation of drug names alone; it rewards understanding of why a finding is pathognomonic. For example, distinguishing ecthyma from superficial impetigo hinges on the depth of ulceration and the presence of a punched-out ulcer with a dirty grey base, not just the causative organism. Similarly, the Nikolsky sign is positive in Pemphigus Vulgaris but negative in Bullous Pemphigoid — a distinction that has appeared in multiple PYQ stems.

The subject intersects directly with your MBBS internship rotations in Medicine, Paediatrics, and Community Medicine. Leprosy, for instance, is simultaneously a Dermatology topic (classification, lepra reactions, MDT) and a Community Medicine topic (NLEP targets, elimination criteria). Scabies management overlaps with Pharmacology (permethrin 5% vs benzyl benzoate 25%). Psoriasis management bridges Dermatology and Immunology through biologics like secukinumab (anti-IL-17A). This cross-subject linkage means a single well-understood topic can yield marks in more than one paper section.

The NEET PG syllabus for Dermatology spans 43 topics across 12 body systems, but the effective high-yield core is narrower. Infections and infestations (Impetigo, Herpes Simplex/Zoster, Dermatophytosis, Scabies) account for roughly 30–35% of Dermatology questions. Immunobullous disorders (Pemphigus Vulgaris, Bullous Pemphigoid) and papulosquamous diseases (Psoriasis, Lichen Planus) together contribute another 30–35%. Leprosy — classification by Ridley-Jopling scale, Type 1 vs Type 2 lepra reactions, and WHO MDT regimens — is consistently the single highest-yield cluster, appearing in 2–3 questions per paper cycle.

A common misconception is that Dermatology is a "visual subject" that can be prepared by browsing image atlases alone. NEET PG 2026 vignettes are text-heavy and require you to interpret histopathology descriptors (e.g., "acantholysis above the basal layer" = Pemphigus Vulgaris), immunofluorescence patterns (linear vs fishnet/lace-like), and smear indices (Bacteriological Index in leprosy). Another misconception is that Lichen Planus is low-yield — its 6 Ps (planar, purple, polygonal, pruritic, papules, plaques) and the Wickham's striae finding appear regularly in single-best-answer stems.
