Pheochromocytoma (Pheo) is present in 10%\u201315% of cases and can be isolated or associated with other lesions such as haemangioblastomas, kidney cysts or cancer and pancreatic lesions. In VHL patients, Pheos generally secrete norepinephrine and are located in the adrenals. Extra\u2010adrenal Pheos (paragangliomas, PGLs) are rare.<\/jats:p><jats:p><jats:bold>Objective\u2002<\/jats:bold> While performing genetic testing in patients affected by apparently sporadic Pheos or PGLs, we found two novel different VHL germline mutations in two females who presented with two distinct very uncommon clinical pictures. One patient was studied for the presence of an adrenal incidentaloma and the other for the presence of a neck tumour.<\/jats:p><jats:p><jats:bold>Methods and results\u2002<\/jats:bold> Patients coding regions and exon\u2013intron boundaries of RET (exons 10, 11, 13\u201315), VHL, SDHD, SDHB and SDHC genes were amplified and sequenced. We identified two novel VHL point mutations: a <jats:italic>L198V<\/jats:italic> missense mutation in a 32\u2010year\u2010old female affected by a right adrenal compound and mixed tumour constituted by an epinephrine secreting Pheo, a ganglioneuroma and an adrenocortical adenoma, and a <jats:italic>T152I <\/jats:italic>missense mutation in a 24\u2010year\u2010old female affected by a left carotid body tumour. No other lesions were found in the patients or in the VHL mutation positive relatives.<\/jats:p><jats:p><jats:bold>Conclusions\u2002<\/jats:bold> These cases enlarge the list of VHL mutations and add new insights in the clinical variability of VHL disease, thus confirming the importance of genetic testing in patients affected by apparently sporadic Pheos or PGLs.<\/jats:p>","DOI":"10.1111\/j.1365-2265.2007.03131.x","type":"journal-article","created":{"date-parts":[[2008,4,11]],"date-time":"2008-04-11T02:14:09Z","timestamp":1207880049000},"page":"762-768","source":"Crossref","is-referenced-by-count":19,"title":["Uncommon clinical presentations of pheochromocytoma and paraganglioma in two different patients affected by two distinct novel VHL germline mutations"],"prefix":"10.1111","volume":"68","author":[{"given":"Tonino","family":"Ercolino","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucia","family":"Becherini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Valeri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michele","family":"Maiello","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Sole","family":"Gaglian\u00f2","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriele","family":"Parenti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matteo","family":"Ramazzotti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisa","family":"Piscitelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Simi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pamela","family":"Pinzani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriella","family":"Nesi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donatella","family":"Degl\u2019Innocenti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nico","family":"Console","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlo","family":"Bergamini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Massimo","family":"Mannelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,11,19]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)13643-4"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.8493574"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-199711000-00001"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2002-021466"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.32.11.885"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00223868"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.33.4.328"},{"key":"e_1_2_6_9_2","first-page":"415","article-title":"von Hippel\u2010Lindau disease and endocrine tumour susceptibility","volume":"13","author":"Woodward E.R.","year":"2006","journal-title":"Human Molecular Genetics"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005392-199909010-00004"},{"key":"e_1_2_6_11_2","doi-asserted-by":"crossref","first-page":"1999","DOI":"10.1210\/jcem.86.5.7496","article-title":"Pheochromocytomas in von Hippel\u2010Lindau syndrome and multiple endocrine neoplasia type 2 display distinct biochemical and clinical phenotypes","volume":"86","author":"Eisehofer G.","year":"2001","journal-title":"Journal of Clinical Endocrinology and Metabolism"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.2004.030353"},{"key":"e_1_2_6_13_2","first-page":"334","article-title":"Adrenal ganglioneuroma\u2013pheochromocytoma secreting vasoactive intestinal polypeptide.
