title: [Bilateral pheochromocytoma associated with duodeno-jejunal GIST in patient with von Recklinghausen disease: report of a clinical case].
abstract: The authors present the case of a 60-year-old male patient suffering from von Recklinghausen's disease (neurofibromatosis type I, NF1) with bilateral pheochromocytoma and occasional intraoperative reports of duodenojejunal GIST (GastroIntestinal Stromal Tumour). Through a review of the literature the authors analyze the frequency and the features of bilateral pheochromocytoma and its rare histological variant, the so-called composite pheochromocytoma, characterized by the combination of pheochromocytoma and ganglioneuroma or ganglioneuro-blastoma. Bilaterality of pheochromocytoma is more frequent in patients with familiarity for pheochromocytoma without NF1. Composite pheochromocytoma accounts for about 3% of total pheochromocytomas. In addition, the authors summarize the present knowledge about gastrointestinal stromal tumours and investigate the possible association between them and NF1 or pheochromocytoma, concluding that any such association is purely casual, while confirming the well known, genetically determined association between NF1 and pheochromocytoma.
