Abstract
Pheochromocytomatosis is defined as a multifocal cell dissemination limited to the operatively opened space with no signs of distant metastasis. After primary adrenalectomy due to a pheochromocytoma this is a rare and underrecognized manifestation of a tumor recurrence. Between 2010 and 2019 a total of 5 patients with the presentation of pheochromocytomatosis were treated in this center. Clinical and survival data were compared to 12 patients with a metastasized pheochromocytoma. Patients presenting with pheochromocytomatosis showed a better but not significant overall survival (136.8 vs. 107 months). Furthermore, patients with pheochromocytomatosis presented more often with a noradrenaline secretion type. Tumor recurrence in the pheochromocytomatosis group occurred on average 69.2 months after the initial diagnosis and was therefore much later than in patients with distant metastases from a pheochromocytoma (39 months, p = 0.13). This article outlines this special manifestation of recurrence of a pheochromocytoma based on this patient collective. Besides technical operative aspects there appears to be evidence for tumor-specific factors that promote the development of pheochromocytomatosis. Importantly, it seems that all patients with a pheochromocytoma should receive lifelong aftercare and that patients should be closely monitored during the first 5 years after surgery.
