Gomori

Gomori is a surname of Hungarian origin that has become associated with several histological staining techniques named after a pathologist with that name. In medical literature, the Gomori designation is used for stains and staining methods used to visualize specific tissue components and microorganisms.

One of the best-known Gomori stains is the Gomori methenamine silver stain (GMS), also referred to as the Grocott-Gomori stain. This method uses silver impregnation to visualize fungal cell walls and related organisms, staining them black against a pale background. It is widely used in diagnostic pathology to detect fungi such as Candida, Aspergillus, and Pneumocystis jirovecii in tissue sections and respiratory specimens.

Gomori trichrome is another stain associated with the name. It is used to differentiate tissue elements, typically highlighting muscle fibers and collagen in contrasting colors, which helps in evaluating connective tissue diseases and certain renal or hepatic biopsies.

Gomori reticulin stain is a silver-based technique for visualizing reticular fibers, providing detail about the framework of various organs, including the liver, spleen, and bone marrow. This stain supports assessment of architectural changes in disease, such as fibrosis or infiltrative processes.

Gomori aldehyde fuchsin and related Gomori stains extend to elastic and other tissue components, enabling selective visualization of specific fibers and structures. Collectively, the Gomori family of stains remains a foundational group of histological tools used to characterize tissue architecture and detect infectious agents in pathology.
