Esthesioneuroblastoma with widespread distant metastasis: Case report and literature review.

Esthesioneuroblastoma (ENB) is an uncommon sinonasal tract tumor, and it is even more uncommon among all neoplasms. Literature regarding the incidence and spread of the disease is limited. The prognosis of metastatic disease is poor. In this report, we present a case of recurrent ENB in a young woman involving metastasis to the neck, lungs, and ovary. Metastasis to the cervical lymph nodes is relatively common, but metastasis to the lungs is rare. Furthermore, to our knowledge, no cases of ovarian metastases of ENB have been reported. This case highlights the potential for widespread metastatic disease, suggesting the need for more frequent and thorough surveillance of patients diagnosed with recurrences of this tumor.
