Overview
Fever and skin rash are very common symptoms seen in pediatric populations both in clinic and hospital settings. Disease states associated with these symptoms are varied and can range from benign to extremely severe illness requiring prompt intervention in the emergency room or even ICU. Therefore, a vast knowledge of these disease states is very important as oftentimes, diagnosis is mainly clinical.
Historical Perspective
- [Disease name] was first discovered by [scientist name], a [nationality + occupation], in [year] during/following [event].
- In [year], [gene] mutations were first identified in the pathogenesis of [disease name].
- In [year], the first [discovery] was developed by [scientist] to treat/diagnose [disease name].
Classification
Febrile rashes can be classified based on morphology (maculopapular, pustular, vesicular, etc); based on distribution of spread (systemic and localized); based on pattern of occurrence (acute and chronic); based on the cause (infectious and non-infectious) [1].
Common types of rashes encountered in clinical practice [1]:
| Type of Rash/Lesion | Description |
|---|---|
| Macule | flat, circumscribed, usually <1cm in diameter |
| Papule | raised/elevated lesion <1cm in diameter |
| Maculopapular | combination of both macules and papulus |
| Nodule | papule in deeper dermis or subcutaneous tissue |
| Pustule | circumscribed raised lesion containing purulent material |
| Vesicle | circumscribed elevated skin lesion usually <1cm containing fluid |
| Bulla | Bigger vesicle (>1cm and containing fluid) |
| Purpura | non-blanching papules or macules due to extravasation of RBCs |
| Petechiae | non-blanching pinpoint unraised spots usually measuring <2mm in size |
