Extra mammary tumors metastasis to the breast

ABSTRACT

In patients with known extramammary malignancies, Metastatic disease should be considered in the differential diagnosis of a palpable breast mass, particularly if there is a history of extramammary malignancy. Breast metastasis is usually indicative of diffuse metastatic disease and a poor prognosis. Biopsy and careful review of previous pathologic material assures prompt treatment and avoids an unnecessary radical operation. Breast metastases from extramammary tumors are rare with few cases reported. Four cases of metastasis to the breast are presented and the diagnostic problems of this condition are reviewed. Correlation between the histology of primary tumor and the cytology of breast metastatic tumors can avoid the surgical breast biopsy and unnecessary mastectomy. In conclusion, Metastasis to the breast has poor prognosis. We report a case of metastasis leukemia to breast presenting as a breast lump
