UK national audit of breast fine needle aspiration cytology in 1990-91: diagnostic criteria.

Abstract

A survey into the practice of fine needle aspiration cytology of the breast amongst members of the British Society for Clinical Cytology in 1990 and 1991 was performed. This paper presents their reported use of diagnostic categories in reporting and the criteria found useful in the diagnosis of benign and malignant disease. A wide variety of diagnostic categories are in use. The criteria used in diagnosis largely follow recommendations found in standard textbooks, but some less well recognized features were also suggested.
