[Cytological aspects of various particular varieties of breast epitheliomas].

Needle aspiration for cytological investigation has been used at the Foundation Curie since 1954. Until 1973, no less than 3,176 mammary tumours have been studied by this method and comparison made with the histological findings. In the whole group some relatively rare carcinomas have been encountered -- mucoid, medullary, adenoid cystic, squamous and apocrine. Each category is described from the cytologic viewpoint and illustrated with an appropriate cyto/histologic example to show what a high degree of precision may be attained by diagnostic cytology in mammary cancer.
