Management of a Composite Pheochromocytoma (Pheochromocytoma/Neuroblastoma) in Adult Patient Recurring After Several Years: A Complex Case Report

Le résumé fourni par la source

Pheochromocytoma/neuroblastoma composite tumors are rare entities for which little is known. We report an atypical case of a 39-year-old man with secondary bone locations of a composite tumor, 7 years after resection of adrenal neuroblastoma, with constitutional alteration of SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily A, member 4 whose role is unknown. The diagnosis of a peripheral neuroblastic tumor in adulthood is difficult and even more so when it is a composite tumor. In the absence of a standard of care, management is varied and discussions about treatment modalities for these patients are complex.
