    The role of metabolic enzymes in mesenchymal tumors and tumor syndromes: genetics, pathology, and molecular mechanisms.
    Lab Invest 2018 Apr 16;98(4):414-426. Epub 2018 Jan 16.
    Department of Pathology, Leiden University Medical Center, Leiden, The Netherlands.
    The discovery of mutations in genes encoding the metabolic enzymes isocitrate dehydrogenase (IDH), succinate dehydrogenase (SDH), and fumarate hydratase (FH) has expanded our understanding not only of altered metabolic pathways but also epigenetic dysregulation in cancer. IDH1/2 mutations occur in enchondromas and chondrosarcomas in patients with the non-hereditary enchondromatosis syndromes Ollier disease and Maffucci syndrome and in sporadic tumors. IDH1/2 mutations result in excess production of the oncometabolite (D)-2-hydroxyglutarate. Read More

    [Vascular anomalies. Part II: vascular malformations].
    Chirurg 2018 Apr;89(4):319-330
    Klinik und Poliklinik für Gefäßchirurgie und Endovaskuläre Chirurgie, Universitätsklinikum, Universität zu Köln, Kerpener Str. 62, 50937, Köln, Deutschland.
    Vascular malformations are congenital vascular anomalies with normal endothelial turnover, which can affect the whole vessel tree (arterial, capillary or lymphatic) both as isolated defects or as part of a syndrome. Developmental errors during embryogenesis, such as abnormal signaling processes that control the apoptosis, maturation and growth of vascular cells, lead to the persistence of vascular plexus cells with some degree of differentiation. Vascular malformations are usually present at birth, although symptoms or complications may be manifested later. Read More

    Maffucci Syndrome. An Interesting Case and a Review of the Literature.
    Bull Hosp Jt Dis (2013) 2015 Dec;73(4):282-5
    Maffucci syndrome, a rare sporadic form of enchondromatosis, is characterized by hemangiomas and multiple enchondromas, benign cartilaginous tumors that arise near growth plates. Previous studies demonstrate that individuals diagnosed with Maffucci syndrome have approximately 100% lifetime risk of malignant transformation. Identification of Maffucci syndrome by surgical excision and pathological diagnosis can be life-saving due to its high malignant potential relative to other subtypes of enchondromatosis such as Ollier's disease.
