The term erythrokeratodermia is applied to a group of inherited disorders of keratinisation characterized by well demarcated erythematous lesions and hyperkeratotic plaques. Erythrokeratoderma en cocardes is an atypical variant characterised by the presence of transient hyperkeratotic and erythematous plaques.
