Breast FNA

Breast FNAC – Diagnostic categories

The triple test is an important aspect of investigation and diagnosis of breast masses, comprising clinical examination, mammography (and/or  ultrasonography), and fine-needla aspiration cytology (FNAC).  FNAC is widely adopted because of its accuracy, low cost & easy of use.

I’d like to introduce you with the cytological diagnostic categories and show you  corresponding cytological images for each of them.

Five diagnostic categories are used to classify the cytological report:

1 – Inadequate

Insufficient cellularity, blood obscuring cells, drying artifact, mechanical artifact

2 – Negative for Malignancy

All cells presents without nuclear atypical features

3 – Probably Benign Lesion

High cellularity but without nuclear atypia, papillary groups, few isolated cells

4 – Suspicious for Malignancy

Many isolated cells, mixed cell pattern (one presents atypical nuclei),  high nuclear/cytoplasmic ratio, few cells with atypical nuclei

5 – Malignant Lesion

All cells presents with obviously atypical nuclei, isolated or not, necrosis and/or mitotic figures present

    Nice pictures, Great job.
    Would be even better if some other cyto board related issues addressed.
