title: Olfactory neuroblastoma metastatic to the breast.
abstract: Olfactory neuroblastoma (Esthesioneuroblastoma) is a rare malignant tumour arising from olfactory epithelium. It has a predilection for cervical lymph node metastasis and also has potential for distant metastasis to unusual sites like scalp, face, aorta, spleen, liver, adrenal gland and ovary. We report here a rare case of olfactory neuroblastoma in an adolescent girl with metastatic deposits in the breast. A poor prognosis due to rapidly progressive disseminated disease was observed. The relevant literature regarding metastatic olfactory neuroblastoma and metastasis in the breast from non-mammary malignant neoplasms is reviewed.
