- This dermatological differential diagnosis table is a simplified way of assessing dermatological cases and includes what we think will cover most primary care presentations. This does not mean other conditions should not be considered.
- The body site and morphological division of the clinical conditions presented here is somewhat arbitrary, and the authors have used editorial licence to allow quicker access during the consultation and to prevent duplication.
- In reality skin lesion morphology and the clinical presentation of dermatological conditions are highly variable and complex. Please consult the linked medical websites and images for a fuller description of the disease conditions.
- Many diagnoses are not obvious or apparent at the initial presentation. It may be appropriate to share your diagnostic uncertainty with patient, and also provide specific guidance on when and where patients should seek further advice and follow up.
