Genodermatoses with Systemic Significance — Written Clinical Reasoning · Phys Written Answers

Prompt

DCE-style written reasoning for Genodermatoses with Systemic Significance.

SAQ 1 — Integrated plan (12 marks)

Prompt: Provide a prioritised problem list and management sequence for this presentation. [1] [2]

Model Answer

1. Frame and red flags (3 marks) [1]

State the working diagnosis/syndrome, acuity, and what would force emergency treatment now. [1] [2]

2. Discriminating assessment (3 marks) [2]

List the key history, examination and investigations that separate dangerous differentials from benign mimics. [1] [2]

3. Treatment sequence (4 marks) [1] [3]

Immediate stabilisation, disease-specific therapy, monitoring, and complications prevention. [1] [2] [3]

4. Follow-up and communication (2 marks) [2]

Disposition, safety-net advice, and who owns follow-up. [1] [2]

SAQ 2 — Exam trap defence (8 marks)

Prompt: Name two high-yield traps in Genodermatoses with Systemic Significance and how you avoid them. [1] [2]

Model Answer

Trap one: delayed escalation of a high-risk feature — avoid by explicit red-flag checklist. [1]

Trap two: therapy mismatched to mechanism — avoid by confirming the discriminating test before escalating treatment. [2] [3]
