This report details a fine‐needle aspiration biopsy performed in the investigation of two right breast nodules in a patient with previous history of lumpectomy for infiltrating ductal carcinoma in the same breast 3 years before. Because the cytology was atypical for a mammary carcinoma and cells did not match the morphology of the previous breast carcinoma, a tissue biopsy was recommended, revealing the presence of metastasis from a previously silent primary renal‐cell carcinoma. This report illustrates not only how metastatic lesions in the breast can masquerade clinically as a primary carcinoma but also the necessity for the cautious approach to interpreting the fine‐needle aspiration biopsy of these lesions. Furthermore, essential guidelines necessary to distinguish primary from metastatic lesions in the breast are presented. Diagn. Cytopathol. 1998;18:343–345. © 1998 Wiley‐Liss, Inc.
