Acute onset of painful hairy eruption on dorsum of foot: An interesting story!

Caterpillar dermatitis is a commonly observed dermatological condition in tropical countries. Contact with caterpillar can cause localized stings, eczematous or papular dermatitis, urticaria, and in some cases life-threatening reactions. We report a case of a patient presenting with acute-onset painful hairy eruption on dorsum of the left foot near great toe. Detailed history and investigations led to appropriate diagnosis.
