Hyperparthyreoidism is a syndrome caused by adenoma, hyperplasia or rarely by cancer<br />
of parathyroid glands. Secondary hyperparathyroidism is a common complication<br />
in cases of chronic renal insufficiency, with clinical and biochemical signs of increased<br />
function of parathyroid glands. It may be so pronounced that surgery is necessary. Sometimes<br />
medical treatment hyperparthyreoidism consist percussing inactivity of the tumor<br />
of parathyroid glands with alcohol. Both procedures demand preoperative localization<br />
of the tissue of the parathyroid glands. The preoperative localization of abnormal, nonpalpable<br />
parathyroid glands in patients with hyperparthyreoidism is largely dependent<br />
on use of high-resolution sonography. However, such a technique has some limitations<br />
and aid of fine needle biopsy (FNAB) may be relevant. On the other hand, cytology also<br />
has some limitations in identification of parathyroid cells. The accuracy of diagnosis of<br />
suspected enlarged parathyroid glands can be improved by combination of ultrasound<br />
examination, ultrasound-guided FNAB and simultaneous analysis of the obtained cell<br />
material by cytology, cytochemistry and immunocytochemistry. A systematic morphologic<br />
description will be given in stained smears all cell types and their cytomorphologic<br />
presentation, with use chromogranin A and calcitonin immunocytochemistry. Conclusion:<br />
Medical treatment hyperparthyreoidism consists of surgical removal of magnified<br />
parathyroid glands or percussing inactivity of tumor of parathyroid glands with alcohol.<br />
It is beneficial for surgeons to know the number, the size, and locality of parathyroid<br />
glands prior to surgery, so they can plan the operative procedure and make it shorter<br />
and safer.<br />
