CRH and hereditary pheochromocytoma-paraganglioma: Some CRH-secreting tumors (pheochromocytoma in this case) could be misdiagnosed as ACTH-secreting tumors because preoperative inferior petrosal sinus sampling (IPSS) for ACTH assays, adrenal vein sampling for ACTH and CRH assays, and postoperative immunostaining for ACTH and CRH are not routinely performed.
