Tissue microarray technology has potential applications in the practice of diagnostic histopathology.
In the stained slides,the areas of the tumor were identified for the preparation of tissue microarray TMA.
The analysis was performed through the evaluation of tissue microarray slide stained by immunohistochemical technique.
The tissue microarray slides, as well as the immunohistochemical staining, were examined by two pathologists, blinded to the evaluations.
