Abstract


We present a case of a 65 year old female with newly diagnosed primary peritoneal serous carcinoma who was found to have indeterminate segmental microcalcifications in the right upper outer quadrant with a mildly enlarged right axillary node on mammogram. There was no associated breast mass on ultrasound. Core biopsy of the right axillary lymph node and right upper outer quadrant breast microcalcifications confirmed the presence of breast metastases at both sites from primary peritoneal serous carcinoma. This case highlights the importance of histopathological correlation of any breast and axillary abnormalities in patient with primary extramammary malignancy. Imaging features of metastatic lesions to the breast are also reviewed.
