"Clear Cell" refers to a type of cell that appears transparent under a microscope due to its low content of cytoplasmic organelles. This characteristic is often observed in certain types of tumors, such as clear cell carcinoma, where the cancer cells have a distinct appearance that can aid in diagnosis. In addition to its role in pathology, clear cells can also be found in normal tissues, such as in the kidney where they are part of the renal tubules. These cells play a crucial role in the filtration and reabsorption processes essential for maintaining fluid and electrolyte balance in the body.
