Practice, The Dermoscopy Quiz

Pattern recognition only sticks with deliberate practice, the 2026 quiz format uses spaced cases across the diagnostic spectrum.

By Dr. Yehonatan KaplanPublished Updated

In brief

The single most-watched session of any AAD dermoscopy block is the case-based quiz. The format works because pattern recognition is built through deliberate practice, the more cases you see with feedback, the faster the visual library compiles. The Swanson 2026 quiz mixed 'classic textbook' cases with deliberate distractors to reinforce both pattern lock-in and second-look discipline.

Clinical content

01Quiz methodology principle: see the lesion clinically + dermoscopically, commit to a diagnosis, then receive the path correlation. Feedback fixes pattern recognition durably.

02Distractor design. The quiz mixes high-confidence cases with deliberate close mimics (pigmented BCC vs nodular melanoma; SK with rarities; AK vs LM) to train the second-look reflex.

03Calibration metric. After 100 cases, log your sensitivity and specificity by diagnosis. The cases you miss define the next study list.

04Spaced repetition is the modern complement to the live quiz: re-review missed cases at increasing intervals (24 h, 1 week, 1 month) to lock in correction.

Key dermoscopic features

Pattern-first commitment
Force a primary pattern (network/parallel/starburst/etc.) before reading sub-features.
Polarized toggle on every case
Train the muscle memory to look for polarized-only features (rosettes, crystalline lines).
Vessel-only diagnosis exercise
Cover the pigment, name the vessel pattern, list the differential, trains amelanotic recognition.
Color-only diagnosis exercise
Cover the structures, name the color combination, list the differential.

High yield clinical points6 pearls in 3 groups

Recognition & pattern analysis

2 points
1
Vessel-only and color-only drills. Cover the rest of the dermoscopic image and force diagnosis from one feature class, trains amelanotic and pigment-poor case recognition.
2
Use polarized on every case. Quiz discipline: toggle polarized on every case, even when the diagnosis seems obvious in non-polarized.

Diagnostic criteria & thresholds

1 point
1
Commit before reading. Force a primary diagnosis before sub-feature analysis; trains pattern recognition over checklist reliance.

Pitfalls & mimics

3 points
1
Log misses by category. Record which diagnoses you systematically miss and double the practice cases in those categories.
2
Spaced repetition. Re-review missed cases at 24h / 1 week / 1 month, durable correction beats one-shot exposure.
3
Calibrate sensitivity vs specificity. Track your false positive vs false negative ratios per diagnosis, adjust threshold accordingly.

Notable updates & conceptual milestones2 updates

Adaptive AI quiz platforms

2024-2026

Quiz apps (DermNet, IDS QuizApp, custom AAD) adapt difficulty per user, reinforcing weakness areas.

Validated dermoscopy curricula

2023-2026

AAD/IDS endorsed curricula at residency level, competency-based progression rather than time-based.

Bottom line

Pattern recognition only sticks with deliberate practice, the 2026 quiz format uses spaced cases across the diagnostic spectrum.
