Gross lesion is a medical term used to describe an abnormality that is visible to the naked eye. The word "gross" is pronounced /ɡrəʊs/, with the letter "o" being a long vowel sound. The word "lesion" is pronounced /ˈliːʒən/ with a silent "s" and a long "e" sound. The spelling of this word follows English language conventions, where "gross" is spelled with the letter "o" and "lesion" with the letters "l-e-s-i-o-n."

A gross lesion refers to any observable abnormality or alteration in the structure or appearance of a tissue or organ that can be detected with the unaided eye during a medical examination or autopsy. It is typically used in the field of pathology to describe macroscopic changes in tissues or organs that are visually apparent without the need for a microscope.
Gross lesions can be caused by a wide range of factors, including infections, trauma, tumors, inflammation, genetic disorders, and metabolic abnormalities. These lesions can manifest as changes in size, shape, color, texture, or consistency of the affected tissue or organ. Common examples of gross lesions include cysts, ulcers, tumors, abscesses, hemorrhages, and infarcts.
The identification and evaluation of gross lesions play a crucial role in diagnosing diseases and determining their underlying causes. Pathologists and other healthcare professionals use their expertise to thoroughly examine and describe the gross lesions they observe, often comparing them to normal anatomical characteristics. This information provides valuable insights into the nature and severity of diseases, aiding in the development of appropriate treatment plans.
In summary, a gross lesion refers to a visible abnormality or change in the appearance of a tissue or organ that can be detected without the need for a microscope. It is an essential component in the field of pathology and contributes to the identification, diagnosis, and understanding of various diseases.

The word "gross lesion" does not have a specific etymology of its own. Instead, it is the combination of two separate words: "gross" and "lesion".
The term "gross" comes from the Old French word "gros" meaning "big" or "thick". It entered the English language in the 14th century, retaining the meaning of "coarse or large in nature".
The word "lesion" comes from the Latin word "laesio", meaning "hurt" or "injury". It was used in English since the late 16th century to denote any abnormal structural changes in an organ or tissue caused by disease or injury.
Therefore, when combined, the term "gross lesion" refers to a significant, visible, or macroscopic abnormality or injury seen during a medical examination or pathological study.
