title: Leucocyte common antigen in the differential diagnosis of Hodgkin's disease.
abstract: The utility of immunohistochemical staining for leukocyte common antigen (LCA) in the differential diagnosis of Hodgkin's disease was studied in a series of 42 cases of Hodgkin's and non-Hodgkin's lymphoma and compared with Leu M-1, a proposed marker for Reed-Sternberg cells. LCA staining of neoplastic cells was absent in 23 of 24 cases of Hodgkin's disease but present in 16 of 18 cases of non-Hodgkin's lymphoma including eight of 10 cases with pleomorphic Reed-Sternberg-like cells. Leu M-1, in contrast was present in 14 of 24 cases of Hodgkin's disease, but also in five of 18 cases of non-Hodgkin's lymphoma including five of 10 cases with pleomorphic Reed-Sternberg-like cells. Immunohistochemical staining for LCA appears useful in the differential diagnosis of Hodgkin's disease and appears to be a better discriminant than Leu M-1.
