Introduction: Doege-Potter syndrome (DPS) is a rare paraneoplastic syndrome consistent in non-islet-cell tumor hypoglycemia associated with solitary fibrous tumor (SFT). Pathogenesis of hypoglycemia has been attributed to the production of insulin-like growth-factor-2 (IGF-2) by tumor cells. We report two DPS patients with metastatic extrapleural SFT.Case 1: A 42-year-old man with SFT of the mesocolon that had been operated in 2010, presented with metast...

Introduction: Pheochromocytomas (Pheo) may appear sporadically (SPheo) or as an autosomal dominant inherited disease, named as familial PHEOs (FPheo). The latter are present in younger patients, and usually with multiple tumors, but may occur in patients with apparently simple sporadic tumors with no other syndromic features.Material and methods: Clinical data of all consecutive patients underwent surgery for Pheo over 35 years in two tertiary referral c...

Background: Individuals with neurofibromatosis type-1 (NF1) carry an increased risk of pheochromocytoma (PHEO). Detection strategy is unknown but most experts recommend screening if hypertension develops.Objective: Report the characteristics of PHEO in patients with NF1 (NF1 group) and compare them with non-NF1-associated PHEO (non-NF1 group).Methods: Retrospective cohort study of patients undergoing PHEO resection in two Spanish t...

Introduction: The widespread use of abdominal computed tomography and magnetic resonance imaging has led to a rise in the diagnosis of incidental adrenal lesions, some of them are pheochromocytomas (Pheo).Objective: To investigate the differences between incidental (IPheo) and symptomatic Pheo (SPheo).Methods: A multicenter retrospective study on clinical and pathological characteristics, treatment and outcome in patients with Pheo...

Introduction: Malignant pheochromocytoma (MPheo) is diagnosed by the presence of invasion of adjacent structures or distant metastasis. Predictive factors of malignancy for pheochromocytoma (Pheo) are not well known.Material and methods: We retrospectively analyzed clinical, biochemical, radiological characteristics as predictors for malignancy in patients with Pheo in two Spanish tertiary hospitals during the past 35 years. We also evaluated time of rec...

Introduction / Background: Patients with advanced GEP-NENs often present with metabolic disorders and oncological treatments may increase malnutrition risk as well as alterations on body composition. Several studies have suggested that sarcopenia is independently associated with a worse prognosis in oncological patients. Sarcopenia predicts survival regardless of body weight; moreover, a reduced muscle mass is not only observed in cachectic individuals but also in overweight p...
