Bone metastasis of malignant pheochromocytoma four years after adrenalectomy

摘要

Malignant adrenal pheochromocytoma is an uncommon entity with low 5-year survival rate. Early diagnosis and adrenalectomy often yields good clinical outcome. The aim of the present case study is to report a 64-year-old Brazilian man with bone metastases of malignant pheochromocytoma first diagnosed and treated by right adrenalectomy four years ago. Recent evidence emphasized the recommendation about the safest duration of follow up, which should be at least 10 years from the first operation or first diagnosis of adrenal pheochromocytoma.
