Breast metastasis from lung adenocarcinoma diagnosed with fine needle aspiration cytology: a case report.

Metastases to the breast from extramammary neoplasms are very rare. Correct diagnosis of breast malignancy is important for establishing appropriate management and for avoiding unnecessary radical surgery. Metastasized breast malignancies from non-small cell lung carcinoma are extremely rare. Here we report a 55-year old female patient with breast metastasis from lung adenocarcinoma which was diagnosed with fine needle aspiration cytology and confirmed by immunocytochemistry.
