[The association between pheochromocytoma and brown fat pseudotumor]

A new case of an association between phaeochromocytoma and a brown fat pseudo-tumour is presented, with arteriographic and histological documents. The case serves to emphasize the difficulties in diagnosis related to the confusing coexistence of the two entities and to discuss the role of catecholamines in the growth of brown adipose tissue under normal and pathological circumstances.
