Somatic IDH1 mutation in a pituitary adenoma of a patient with Maffucci syndrome.

ABSTRACT: Maffucci syndrome is a rare disease characterized by multiple enchondromas and soft-tissue hemangiomas. 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 (IDH1) or isocitrate dehydrogenase 2 (IDH2). 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 IDH1/2 mutations. Clinical, radiological, and biochemical assessments were performed. Genotypic studies used
