Contact Dermatitis – Board-Style Questions

What this deck covers

Contact dermatitis in 18 board-style clinical cases with worked explanations. Each case gives you a clinical vignette, four options, the correct answer, and an explanation of why each of the other three is wrong, with the guideline or textbook it follows named on the answer.

Board-style teaching questions for paediatricians and trainees preparing for paediatric board, MRCPCH and licensing examinations. Written from published guidelines and standard paediatric textbooks, with the source named on every answer.

The 18 cases, in order

1. Both earlobes, and the watch too
2. Two days, not two minutes
3. Hands that are always wet
4. Streaks up the forearm
5. Puffy lids, and nothing else
6. A band around the middle
7. Only where the sleeve left it bare
8. A ring round the mouth
9. The holiday tattoo
10. Settling which one it is
11. What goes on her back
12. Coming back on the Friday
13. A positive that means nothing
14. The morning after the dye
15. The cream that made it worse
16. Earrings she can wear
17. The apprentice and her hands
18. Will she grow out of it

Diagnoses and management options tested

Across the 18 cases you are asked to choose between options such as: Atopic eczema flaring at the sites where her skin is thin, A delayed response driven by sensitised T cells, Allergy to the rubber gloves worn during long shifts, A viral eruption that began the weekend before, Transfer from her nails to the thin eyelid skin, Chlorine from the water of the swimming pool, An allergy to the fabric of the sleeve he wore, A fungal infection of the skin all around the mouth, She is now sensitive to a common hair dye chemical, Skin prick testing to a panel of common foods, Only the standard series, because brands vary too much, A repeat is needed because the first one was rushed, Whether he meets that material where the rash sits, Intramuscular adrenaline followed by an antihistamine.

Clinical pearls from this deck

• Ears, watch and buckle together: suspect nickel.
• Allergic contact rash appears about two days later.
• Sore rather than itchy, and worse with water: irritant.
• Itchy lines after the garden: think plant contact.
• Eyelids alone: look at what the hands carry up.
• A rash shaped like the elastic: rubber allergy.

Work through the deck once for recognition, then again a week later to test yourself — each question gives the answer and explains why every other option fails.
