Staining helps identify the different structures within the tissues; also it allows distinctions to be made between them. Most dyes have an acidic or basic compound. The tissue components that mostly stain with the basic dyes are called basophilic, on the…

individual cells having an increased nuclear-to-cytoplasmic ratio, round nuclei with vesicular chromatin pattern and prominent nucleoli. The tumour showed CD20, BCL6, and CD10 immunopositivity was demonstrated. EBER was positive and there was patchy BCL2 staining. The case was reported as a diffuse large B-cell lymphoma.
