[A case of malignant paraganglioma].
Herein we report a case of paraganglioma. The metastatic lesion was incidentally found in a 64-year-old man by chest roentgenography. The primary tumor was extra-adrenal and was revealed to be malignant. The patient was normotensive without clinical symptoms despite extreme high serum and urinary dopamine levels. A venous injection of 5 mg metoclopramide elicited a significant increase of the blood pressure. This phenomenon disappeared after surgical excisions of the primary and metastatic lesions. The metoclopramide test is considered to be useful to diagnose asymptomatic paraganglioma.
