Immunohistological patterns of immunoglobulins in dysplasias, benign neoplasms and carcinomas of the breast.


IgA, IgG, IgM and IgE were studied in 61 carcinomas, 24 tissues peripheral to carcinomas, 16 benign neoplasms and 15 dysplasias of the breast. Mono- and double-layer direct immunofluorescence procedures applying FITC- and TRITC-conjugated antisera were used on cryostat and paraffin sections for evaluation of immunoglobulins in plasma cells, cancer cells and… (More)
