Abstract
- We report a 62-year-old man with histologically confirmed olfactory neuroblastoma who also had the syndrome of inappropriate antidiuretic hormone secretion (SIADH). An olfactory neuroblastoma is a rare malignancy of the nasal cavity or paranasal sinuses and is rarely associated with excess hormone syndromes. The ectopic production of antidiuretic hormone (ADH) by a tumor is most often due to a small cell carcinoma of the lung, while less common causes include an olfactory neuroblastoma. To our knowledge, this is the first reported case of SIADH secondary to an olfactory neuroblastoma in Korea.
