Fine needle aspiration biopsy cytology is part of the diagnostic triad in the evaluation of breast pathology, along with clinical and mammography or ultrasound findings. The Yokohama international system of the International Agency for Cytology has been proposed to report fine needle puncture-aspiration biopsy breast cytology, through 5 diagnostic categories: Inadequate/insufficient, benign, atypical, suspicious for malignancy and malignant, including in each of these definitions, key cytological diagnostic criteria and suggestions for clinical management. The objective of this article was to know the guidelines of this new breast cytological classification system for its implementation in this region. Fine needle puncture-aspiration biopsy is a precise and effective method to diagnose different breast lesions, which requires an adequate cell sample and a precise cytomorphological interpretation. The application of standardized Yokohama system will allow to improve the evaluation, diagnosis and clinical management of the breast pathology. Keywords: Breast cytology.

ABSTRACT Cytodiagnostic fine needle aspiration biopsy specimens from toxic goitres were studied for signs of lymphoid infiltration. Comparison with histological sections of specimens obtained by surgery showed that an excess of lymphoid cells in the aspirate smears corresponded to a large number of lymphoid foci in these sections. Excess of lymphoid cells in the fine needle aspirates was also positively correlated with the occurrence of circulating thyroid antibodies against thyroglobulin and/or cytoplasmic antigen, but not with the presence of the long-acting thyroid stimulating factor, LATS. It also varied with age in that it was most common in the youngest patients and in patients between 40–55 years, while lymphoid infiltration was seldom seen in patients over 55 years. A finding of practical clinical interest was that in toxic goitres with cytological signs of lymphoid infiltration hyperthyroidism had less tendency to recur after treatment with thiocarbamide drugs than in those without such signs.
