The first experience of applying the cell block technique in the Republic of Kazakhstan
Method of morphological diagnosis of tumors is helpful in complex cases as it combines the minimally invasive fine needle puncture with the histological material posting techniques. The punctate material was placed in citrate plasma. The formed fibrin convolution was fixed in 10% neutral buffered formalin with the following standard histological posting and paraffin embedding. Monoclonal antibodies to thyroglobulin, TTF1, CK7, CK20 were used. The cellular block technique in a combination with immuno-histochemical test proved to be efficient in diagnosing malignant neoplasms.
