title: [Immunohistochemical diagnosis in fine-needle aspiration cytology].
abstract: This paper reports 25 kinds of polyclonal or monoclonal antibodies by ABC immunohistochemical technique used for 253 cell smears by fine-needle aspiration. The results were: 1. Immunohistochemical diagnosis were classified into 136 metastatic cancers (K12+ EMA+ CEA+ LCA-), 92 lymphomas (LCA+ K12- EMA- CEA-), 4 mesenchymal tumors (Vimentin+), 3 melanomas (S-100+ NSE+), 15 reactive proliferations (K+ lambda+ CD4+ CD8+) and 3 unspecified. 2. The origin of 70 metastatic cancers were classified into 36 lung (HLC3-AB+), 4 gastrointestinal tract (MG7+), 8 thyroid (TGB+), 1 prostate (PSA+), 3 liver (AFP+) and 14 unknown. 3. Immunologic phenotype of 87 lymphomas were classified into 66 cases of B-cell, 4 T-cell, 3 histiocyte, 7 Hodgkin's diseases and 7 unclear. The above results suggest that immunohistochemical method may be used as a new method of diagnosing and differentiating epithelial and non-epithelial tumors, detecting primary focus of metastatic cancer, differentiating between reactive proliferation and lymphoma and specifying immunologic phenotype of lymphoma in cell smears of fine-needle aspiration.
