A case of breast cancer with endocrine features
- 23 Downloads
Cancer with endocrine features rarely occurs in the breast. We report a case of breast cancer with endocrine features in an 80-year-old woman. The tumors were treated by wide excision and a postoperative histopathologic diagnosis of carcinoma of the breast with endocrine features was made. Immunostaining was positive for chromogranin A, neuron-specific enolase and synaptophysin, but weakly argyrophilic. Widespread metastases occurred two months postoperatively, and the patient died of breast cancer 6 months after the first treatment.
