The patient, a 58-year-old woman, first presented with a mass in her left breast as well as multiple osseous metastases and a right femur fracture. Laboratory data revealed a hypokalemic alkalosis. Her plasma ACTH level was elevated. She was diagnosed with breast cancer with ectopic ACTH secretion, and underwent a left mastectomy and axillary lymph node dissection. Histological examination demonstrated a poorly differentiated neuroendocrine carcinoma with ectopic ACTH secretion. Although the signs and symptoms of ectopic ACTH secretion from a breast cancer are frequently subtle, the recognition of ectopic ACTH secretion from breast cancer is important for patient management.}, pages = {71--75}, title = {ACTH-Producing Breast Cancer: A Patient Report}, volume = {53}, year = {2010} }
