Granular

Granular is a term often used in the medical field to describe a texture, appearance, or quality of certain biological materials or conditions. It is derived from the word "granule", which refers to a small particle or grain.

Definition

In a medical context, granular refers to the appearance of a substance, tissue, or organ that is characterized by small, grain-like particles. This can be observed in various medical conditions and biological materials, such as skin, kidney tissues, and certain types of cells.

Granular Appearance in Medical Conditions

There are several medical conditions that are characterized by a granular appearance. For example, granular cell tumor is a type of tumor that has a granular appearance due to the presence of small, grain-like particles in the tumor cells. Similarly, granular cell myoblastoma is a rare benign tumor that also has a granular appearance.

These can include certain types of cells, such as granulocytes, which are a type of white blood cell that have a granular appearance. Other examples include granular leukocytes, which are a type of white blood cell that contain granules filled with enzymes that are released during infections or allergic reactions.
