The application of immunohistochemistry in the differential diagnosis of extranodal lymphoma and anaplastic carcinoma

  • 16 Accesses

Abstract

Thirty-six cases originally diagnosed histologically as malignant lymphoma (ML) or anaplastic carcinoma were reexamined immunohistochemically by leukocyte common antigen (LCA) and epithelial membrane antigen (EMA). 5/18 cases originally diagnosed as “anaplastic carcinoma” and “anaplastic carcinoma? (ML to be excluded)” , showed positive staining for LCA and negative for EMA; whereas 3 cases originally diagnosed as malignancy unclassified turned out to be ML, with the relevant assay performed.
