Olfactory neuroblastoma pulmonary metastasis presenting as a solitary pulmonary mass in an adult: A case report with pathologic correlation

Pulmonary metastasis of an esthesioneuroblastoma is uncommon. In this report, we present a case of an esthesioneuroblastoma pulmonary metastasis in an adult. A 39-year-old man treated with surgical resection of olfactory neuroblastoma was found to have a solitary pulmonary mass on a surveillance computed tomography scan performed 5 years after undergoing primary surgery and radiation treatment. He underwent lobectomy, and histopathology revealed esthesioneuroblastoma metastasis. To our knowledge, no case of esthesioneuroblastoma metastasis presenting as a solitary pulmonary nodule has been described in peer-reviewed literature.
