Abstract
The parathyroid tumours are important to lillow, as they are responSible
for most of primary cases of hyperparathyroidism i.e. about
80 % of cases.
Tumours of prathyroid glands are diagnosed more frequently today
than a decade ago, because it is being sought more aggressively.
~lost hospitals now include calclUm and phosphorus determinat10n
as a part of their admission screening laboratory evaluation as
it is the only means to diagnose tumours as early as possible.
The early diagnosis of parathyroid tumours is badly needed because
of the followmg pomts:-
1. Parathyroid tumours are regarded as the major cause of primary
hyper parathyroidism, and in turn primary hyperparathyroidism,
is thought to occur in 0.1- 0.5% of general population, which
ts good proportion.
2. Parathyroid tumours are very small to be diagnosed by clintcal
examination, and ”’e have to screen any patient with suspicious
symptoms for parathyroid tumours.
3. It 1s very difficult to diagnose parathyroid tumours in its
early stage clinically, as they manifest in their early stage
by non specific symptoms.
