Misleading presentations of malignant breast diseases--role of clinical cytology.

We described two examples with misleading presentations to draw attention to the role of clinical cytology as apart of multidisciplinary approach to breast lesions. In the first case--Paget's disease of the nipple, there was no obvious clinical and radiological evidence of breast cancer, while the second case--primary non-Hodgkin lymphoma of the breast imitated advanced breast carcinoma. The question is whether accurate and fast diagnoses can be made without cytological examinations.
