MEDIUM (TISSUE SIZE 2CM-5CM/TREE(3) BLOCK) Detail

This refers to a medium-sized tissue specimen with a maximum dimension ranging from 2 cm to 5 cm, which requires processing into three paraffin blocks for optimal microscopic examination.

The specimen undergoes:

• Fixation in formalin to preserve tissue integrity.

• Serial sectioning and embedding into three separate paraffin blocks to ensure complete sampling of the tissue.

• Staining (e.g., Hematoxylin & Eosin) for evaluation under a microscope by a pathologist.

This category is commonly applicable to larger biopsy samples or small excised lesions from organs such as the gastrointestinal tract, breast, lymph nodes, uterus, or skin.

It allows for:

• Better assessment of lesion margins

• Detailed architectural and cellular analysis

• Evaluation of multifocal or heterogeneous pathology

• Detection of focal malignancies or inflammatory changes

Medium tissue sampling improves diagnostic accuracy, particularly in complex or borderline lesions.
