Olfactory neuroblastoma metastatic to the breast

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 s ites like scalp, face, aorta, spleen, liver, adrenal gland and ovary. We re port here a rare case of olfactory neuroblastoma in an adolescent girl with metastatic deposits in the breast. A poor prognosis due to rapidly progres sive disseminated disease was observed. The relevant literature regarding m etastatic olfactory neuroblastoma and metastasis in the breast from non-mam mary malignant neoplasms is reviewed.
