Categorization of breast fine needle aspirates in a tertiary care centre in Bagalkot using International Academy of Cytology Yokohama System with Diagnostic Accuracy.

Abstract

Background: Fine needle aspiration cytology (FNAC) has been a preoperative procedure for identifying neoplastic and non-neoplastic breast lesion. Using the International Academy of Cytology (IAC) Yokohama System, breast lesions can be categorized into 5 groups.

Aim: The main objectives of this study was to classify breast fine needle aspirates according to IAC Yokohama system and correlate with histopathological findings.

Materials and methods: All breast FNACs were done prospectively for one month in the department of Pathology. A total of 40 FNACs were examined and classified according to IAC Yokohama system for reporting Breast Cytopathology. Wherever possible, histopathological correlation was done with cytopathology.

Results: In the present study, a total of 4 smears of fine needle aspirations were included and categorized using the IAC system for reporting breast cytopathology. There were 0% cases in C1 category (insufficient), 60% cases in C2 category (benign), 10% cases in C3 category (atypical), 2.5% cases in C4 category (suspicious for malignancy) and 27.5% cases in the C5 category.

Conclusion: FNAC is a safe, rapid and economical out-patient procedure. Using IAC Yokohama system, it helps in diagnosing fine needle aspirates accurately
