Abstract: (10537 Views)
Paraganglioma are tumors that arise within the sympathetic and parasympathetic nervous system. About 10% of paraganglioma spread to distant sites. Malignant potential has been difficult to be determined by histologic characteristic and it is defined after a metastatic lesion or direct invasion found in a site with no residual embryonic paraganglionic tissue. In this case report, a 51-year-old man is presented who had a neck mass from 15 years ago. After resection of the mass, diagnosis was paraganglioma. After 6 months, the patient was involved by tumor recurrence and she was then reoperated, but this time due to lymph node involvement, malignant paraganglioma was diagnosed.
