Introduction: Thymic neuroblastoma with syndrome of inappropriate secretion of antidiuretic hormone (SIADH) in adults is an extremely rare and malignant neoplasm. Although the tumor is known to grow rapidly and have a poor prognosis, its etiology is still uncertain. In 2009, we described a case of thymic neuroblastoma with SIADH. We report here the clinical course over the last 10 years.
Presentation Of Case: A 70-year-old Japanese male with a history of thymic neuroblastoma with SIADH was regularly followed up on an out-patient basis after complete surgical resection for more than 10 years. He remains free of the disease and asymptomatic.
Discussion And Conclusion: Complete surgical removal is considered as one of the treatment options for this tumor if clearly separated from the surrounding tissue with no invasion.
