ostetis fibrosa cystica

Mast cells have been counted in iliac bone biopsies from patients with chronic renal failure treated by haemodialysis, and attempts made to relate mast cells to the various features of azotaemic renal osteodystrophy. There was a significant increase in the number of marrow mast cells in comparison with controls, and haemodialysis has no favourable effect on the marrow mast cell hyperplasia which occurs in chronic renal failure. There was a general tendency towards greater numbers of mast cells in cases with most marked ostetis fibrosa but it was not possible consistently to relate hyperparathyroidism to mast cell numbers...
