Light chain ladders are electrophoretically more homogeneous, are usually kappa, less commonly lambda, light chains, and widely distributed over the gammaglobulin zone Aetiology Light chain ladders are seen in patients with lymphoproliferative diseases—e.g., lymphoma, myeloma, monoclonal gammopathy of undetermined significance, some infections, and inflammatory conditions Tropical medicine A characteristic linear serrated wheal produced by the adherent tentacles of the box jellyfish—Chironex fleckeri, Chiropsolmus quadrigatus, coelenterates native to the Pacific basinladder pattern Lab medicine Light chain ladder A phenomenon that may be seen on routine high-resolution agarose gel electrophoresis–AGE and immunofixation of urine specimens; LCLs are electrophoretically more homogeneous, are usually kappa–κ light chains–less commonly lambda–λ light chains, and widely distributed over the γ-globulin zone; LCLs appear in Pts with lymphoproliferative diseases–eg, lymphoma, myeloma, monoclonal gammopathy of undetermined significance, some infections, and inflammatory conditions Pediatrics A sign on the abdomen in children with an obstructed lower GI tract, seen as parallel loops of distended small intestine, causing a 'stepped' pattern. |
