title: Ectopic functioning adrenocortico-myelolipoma in longstanding Nelson's syndrome.
abstract: A 26-year-old man with the Nelson's syndrome is described, in whom an abdominal tumour developed, accompanied by recurrent Cushing's syndrome 11 years after total adrenalectomy. Upon removal the tumour was a myelolipoma containing islands of adrenocortical-like elements. On incubation of the tumour with radioactive precursors, its capacity to produce cortisol in vitro was shown. The name adrenocortico-myelolipoma is suggested for this tumour.
