Additionally, neuroendocrine tumors including pituitary adenomas have been described in these patients. The underlying genetic etiology lies in somatic mosaicism of mutations in isocitrate dehydrogenase 1 <jats:italic>(IDH1)<\/jats:italic> or isocitrate dehydrogenase 2 <jats:italic>(IDH2).<\/jats:italic> This report describes a patient with Maffucci syndrome who presented with intracranial tumors of the skull base and suprasellar region. The patient underwent resection of both intracranial tumors, revealing histopathological diagnoses of chondrosarcoma and pituitary adenoma. DNA sequencing of the tumors was performed to identify common <jats:italic>IDH1\/2<\/jats:italic> mutations. Clinical, radiological, and biochemical assessments were performed. Genotypic studies used standard Sanger sequencing in conjunction with a target-specific peptide nucleic acid to detect <jats:italic>IDH1<\/jats:italic> mutations in tumor tissues. DNA sequencing demonstrated identical <jats:italic>IDH1<\/jats:italic> mutations (c.394C &gt; T) in both tumors.<\/jats:p>\n<jats:p>To the authors\u2019 knowledge, this report provides the first genetic evidence for the inclusion of pituitary adenomas among tumors characterizing Maffucci syndrome. In patients who are newly diagnosed with Maffucci syndrome, it is appropriate to monitor for development of pituitary pathology and neuroendocrine dysfunction.<\/jats:p>","DOI":"10.3171\/2015.4.jns15191","type":"journal-article","created":{"date-parts":[[2015,10,16]],"date-time":"2015-10-16T16:11:26Z","timestamp":1445011886000},"page":"1562-1567","source":"Crossref","is-referenced-by-count":12,"title":["Somatic
