Light House Polyclinic. 2023 Mar; 22(1): 1-30972-5997http://imsear.searo.who.int/handle/123456789/218343Although breast carcinoma is common, metastatic deposits to the breast from extramammary neoplasms are rare. Clinically and radiologically, metastatic neoplasms may mimic primary benign and malignant neoplasms of the breast. A correct diagnosis of metastasis to the breast is of considerable importance since the treatment of primary and secondary malignancies of the breast is different. We report 4 cases of extra mammary primary cancers metastasizing to the breast, diagnosed by biopsy, in a period of 5 years in our tertiary care centre. Each of the cases had different characteristics. A good knowledge of cytomorphology and histomorphology, together with clinical correlation and comparison with previous histopathological evidence, will prevent a misdiagnosis and aid in optimal management and therapy.Breast malignanciesNon mammary metastasesSecondaries in breastbreast histopathology.Journal ArticleIndiaDepartment of PathologyDepartment of SurgeryDepartment of SurgeryPSG Institute of Medical Sciences & Research, Coimbatore, Tamil Nadu, India
