The origin of clinical organ transplantation revisited

A patient whose illness had begun with edema and hypertension was found to have extreme atrophy of both kidneys.

Preparations included collection of evidence of monozygosity and experimental transplantation of a skin graft from the twin.

The hypertension persisted until the patient's diseased kidneys were both removed. The homograft has survived for 11 months, and the marked clinical improvement in the patient has included disappearance of the signs of malignant hypertension
