Simultaneous local recurrence of retroperitoneal paraganglioma with liver metastases.
A 68-year-old woman with a history of a nonfunctional paraganglioma resected 23 years previously presented with an abdominal mass. Tumor metastases to the liver were seen at the second operation. The tumor had a more pleomorphic appearance, but was otherwise similar to the original tumor. We discuss the difficulty of predicting the later malignant behavior of the tumor from the original biopsy specimen.
