Diagnosis of rare malignant tumours of the breast by FNA cytology--a report of 3 cases.

This report describes the fine needle aspiration (FNA) cytology findings in 3 cases with breast tumours. The characteristic cyto architectural pattern helped in the diagnosis of two papillary carcinomas. The predominant spindle cell pattern with scattered bizarre cells was interpreted as malignant spindle cell tumour in one case. On histopathology, this was diagnosed as metaplastic carcinoma.
