Abstract
Fairly large ectopic calcification in four chronic hemodialysis patients was reported. Control of serum inorganic phosphate was poor in every case and consequently the calcium-phophate product was over 50. Definite intake of phosphate binding agent was mandatory and a low-phosphate diet was tried with success. Cimetidine and calcitonin might prove effective in cases with ectopic calcification.
In two cases, calcified masses were surgically extirpated: Cloudy fluid and block-or powder-like material were contained in a fairly thick capsule, and chemical analyses revealed calcium phosphate.
Ectopic calcification is one of the results following disturbances of calcium-phosphate metabolism, which must be contolled on a daily basis.
