Introduction

Tumor tissue is composed of parenchyma and stroma. Tumor parenchyma is tumor cell and main component of tumor, which has tissue origin specificity. It determines the biology of the tumor and the uniqueness of each tumor.
Usually, the tissue origin, classification, naming, and histological diagnosis of various tumors are identified based on their substantial morphology. At the same time, the degree of differentiation, maturity, and heterogeneity of the tumor parenchyma can be used to determine the malignancy of the tumor. Tumor cells have three significant basic characteristics: immortality, migration, and loss of contact inhibition.

Principle

Polarized light microscopy is a kind of microscope to identify the optical properties of the fine structure of a substance. Any substance with birefringence can be distinguished under a polarizing microscope. The characteristic of a polarized light microscopy is to change ordinary light into polarizing light for microscopic examination in order to identify whether a substance is monorefringent (anisotropic) or birefringent (anisotropic).
1. Monorefractivity and birefringence: When light passes through a substance, if the properties and path of light do not change due to the direction of illumination, this substance has "isotropy" in optics, also known as a single refractor, such as ordinary gases, liquids, and amorphous solids; If the speed, refractive index, absorption, polarization, amplitude, etc. of light passing through another material vary depending on the direction of illumination, this material has "anisotropy" in optics, also known as a birefringent material, such as crystals, fibers, etc.
2. Polarization of light: Light waves can be divided into natural light and polarized light according to the characteristics of vibration. The vibration characteristic of natural light is that there are many vibration planes on the vertical light wave conduction axis, and the amplitude distribution of vibration on each plane is the same. Natural light through reflection, refraction, birefringence and absorption, can be obtained only in one direction vibration of light waves, this light wave is called "polarized light" or "polarized light".
