Metastatic neuroendocrine tumor found on screening mammogram

Background:
Tumor metastatic to the breast is uncommon, and a neuroendocrine tumor metastatic to the breast is even more unusual. The breast lesion can be the first manifestation of a nonmammary malignancy.
Methods:
Metastatic neuroendocrine tumors to the breast have been described in the literature in case reports or very small case series. Because of the small number, current treatment recommendations are not well defined. We present a case report of a metastatic neuroendocrine tumor that first presented as a breast lesion on screening mammography.
Conclusion:
Accurate diagnosis is important for appropriate management, as the treatment for a breast primary neuroendocrine tumor is different than a neuroendocrine tumor metastatic to the breast.
