Desmin Information for Pathologists


53 kDa intermediate filament first described in 1976 (Proc Natl Acad Sci USA 1976;73:4344), present near the Z line in sarcomeres, present in cardiac, smooth and striated muscle (Wikipedia). Expressed before actin in myoblasts. Variable expression in myofibroblasts. Uses by pathologists Common stain used in panels for mesenchymal markers.

Common Uses By Pathologists:

Common stain used in panels for mesenchymal markers. Confirms myogenic origin of tissue / tumors. Helps differentiate smooth muscle tumors (desmin+) from GIST (c-kit+, almost always desmin-). In serous effusion, more common in reactive mesothelial cells (84%) than mesothelioma (8%) or carcinoma (2%, Am J Surg Pathol 2001;25:1405). Diagrams / tables
