Implications for practice
- Mimickers are often presented by parents who are unable to explain the cause of injury; full and careful history must always be taken
- Careful history of sun and possible psoralen exposure must be sought when a blistering rash occurs de novo
- Consideration must be given to traditional remedies, particularly in South Asian populations
- Skin disorders are characterised by progression of the lesions; swabs for culture and sensitivity are advised
- Congenital curvilinear hyperpigmentation may be mistaken for contact burns to posterior calf in infants
