Erythropoietin and renin substrate in cerebellar haemangioblastoma.
We examined eight cerebellar haemangioblastoma tumours from eight patients, aged 16-63 years, 5 females and 3 males. Preoperative haemoglobin values exceeded 180 g/l in four patients, and 150 g/l in four. All high Hb values were normalized upon surgical removal of the tumours. All tumours contained scattered cells which stained positively with antisera against pure human urinary erythropoietin and plasma renin substrate. We conclude that cerebellar haemangioblastomas produce immunoreactive erythropoietin, which shares common antigenic determinants with renin substrate.
