In pathology, the term “gross” refers to observations or examinations made with the naked eye, as opposed to those requiring a microscope for detailed visualization. Gross examination involves looking at the physical characteristics of tissues and organs without any magnification. This can include assessments of size, shape, color, consistency, and any notable abnormalities such as 病变 or 肿瘤. Thus, “gross” in this context is about the scale of observation rather than implying anything unpleasant.

大体检查 is an important initial step in the assessment of surgical specimens and the preparation of a pathology report because it provides the first set of clues regarding the nature of a disease. Findings from a gross examination guide subsequent steps, such as selecting specific areas for closer microscopic examination (histology), which can reveal more detailed information about the changes taking place on a cellular level.
