Fine needle aspiration cytology (FNAC) is a very accurate and safe procedure for the diagnosis of breast malignancies. Although rare, the various malignant tumours like squamous cell carcinoma, metaplastic carcinoma and other types can be diagnosed by their cytomorphological characteristics. But there are certain limitations of FNAC which require final histopathological diagnosis for determining prognosis and therapy (particularly conservative) in patients of breast malignancies. The difficulties encountered, and limitations of FNAC in sub typing three cases of breast carcinoma are discussed.
