Recurrent malignant hypertension: a report of two cases and review of the literature.

Malignant hypertension (MHT) is a rare and life-threatening condition which is defined clinically as severe hypertension accompanied by bilateral retinal haemorrhages and/or hard exudates, with or without papilloedema. If untreated, the prognosis of MHT is poor. With MHT being a relatively rare condition, it would be unusual to see it on more than one occasion in the same patient. We describe in detail two cases from a disease register of 400 cases of MHT seen in one medical centre over 33 years.
