Introduction: Pheochromocytomas/paragangliomas are rare neuroendocrine tumors. Although mostly sporadic, about 1/3 of the cases correspond to inherited autosomal dominant syndromes, often associated with germline mutations of the SDHD, SDHC and SDHB genes. The association with the SDHAF2(SDH5) gene has been recently discovered, with only few cases published worldwide, and it presents as a paraganglioma of the head and neck, without previous known description of other locations...

Introduction: Patients with germline mutations in one of the succinate dehydrogenase (SDH) genes are at substantially increased risk of developing paragangliomas (PGL) and pheochromocytomas (PCC). Mutations in SDHB are the most commonly found gene mutations in PC/PGL and are associated with younger ages at presentation, higher rates of metastases and poorer prognosis. Although familial PGL syndromes were initially thought to predispose only for PCC and PGL, other tumor types s...

Introduction: Successful whole pancreas transplantation is at the present the most effective treatment for type 1 diabetes but allograft dysfunction related with infection, vascular compromise or immunological causes are not uncommon. Usually, graft vascular thrombosis or haemorrhage, as well as infectious complications are responsible for early pancreas graft failure; late cases occur more frequently by immunological causes, either allograft rejection or recurrence of the &#1...
