Abstract
Olfactory neuroblastoma also known as esthesioneuroblastoma is uncommon malignant neoplasm usually occur at roof of nasal cavity. It usually metastasize to lymph node and rarely metastatise to elsewhere including to the salivary glands.There has been only one case of metastasis to the parotid gland reported in 2005.We report a case of an elderly women who underwent an endoscopic nasal surgery for olfactory neuroblastoma, presented with parotid swelling 2 months after the operation which was progressively increases in size. Histopathology and immunohistochemistry confirm the diagnosis of olfactory neuroblastoma metastasized to parotid gland. The patient underwent total conservative parotidectomy, tumour debulking, left cervical lymph node removal with preservation of facial nerve branches and left selective neck dissection was performed. Patient is planned for further chemotherapy and palliative care.
