Haematological aspects of hypophyseal tumours.

This paper is devoted to the study of anaemia in patients with hypophyseal tumours. Anaemia with a red blood cell count of 2.4 million/mm3 to 3.9 million/mm3 was found in 60 of 280 patients (21.7%) with hypophyseal tumours; 52 of the 60 patients were operated on. Similar changes were observed in 25 of 60 cases (41.7%) of craniopharyngioma. Apart from anaemia and a low haemoglobin some of the patients also had anisocytosis, anisochromia, leucocytosis, and haemolytic shock.
