Successful treatment with paclitaxel of a patient with metastatic extra-adrenal pheochromocytoma (paraganglioma). A case report and review of the literature.

This case report describes the history of a patient with an aggressive course of a metastatic extra-adrenal pheochromocytoma (paraganglioma) who received different combination chemotherapy regimens with no or short-lasting clinical benefit. However, during treatment with single-agent paclitaxel, there was a significant clinical improvement, a partial biochemical response and a minor roentgenologic response, which was sustained for 1 year. In this report we present this case and also review the literature on the chemotherapy used for this rare disease over the past 15 years. To enable the activity of paclitaxel against this neoplasm to be determined, more patients need to be treated.
