Frequent incidental discovery of phaeochromocytoma: data from a German cohort of 201 phaeochromocytoma.

Context: Adrenal and extra-adrenal phaeochromocytoma are chromaffin cell-derived tumours that are discovered due to classical symptom triad with headache, sweating and palpitations combined with persistent or paroxysmal hypertension. However, an increasing proportion of phaeochromocytoma seems to be discovered incidentally upon abdominal imaging.

Objective: To specify the exact circumstances of discovery of adrenal and extra-adrenal phaeochromocytoma.
