Background: Abrupt catecholamine release may cause paroxysmal attacks in patients with pheochromocytoma, and is associated with major hemodynamic changes during adrenalectomy. We investigated whether preoperative paroxysmal attacks are associated with further intraoperative adverse hemodynamic changes during adrenalectomy for pheochromocytoma.Material and methods: From 1994 to 2006, 88 patients underwent laparoscopic adrenalectomy for pheochromocytoma. I...

Introduction: Insulinoma is the most frequent functional endocrine tumor of the pancreas but remains rare with an incidence of less than 5 cases by million and by year. It is often sporadic but can occur in the context of MEN1 in about 5% of cases, being then readily multiple. Clinically, it is typically responsible for fasting hypoglycemic episodes. Only one case of multiple insulinomas, with no obvious argument for MEN1 context, has previously been reported (Babic an al., <e...

Background: Adrenocortical cancer (ACC) is an aggressive tumor with heterogeneous prognosis. Previous genomic studies have demonstrated the importance of molecular classification for the prognostic assessment. Among molecular markers, transcriptome profiles “C1A” (steroid and proliferative signature) and “C1B” (immune signature) show the strongest association with outcome. However these markers are determined so far only from frozen tissue samples, sinc...
