Molecular profiling of different glioma specimens from an Ollier disease patient suggests a multifocal disease process in the setting of IDH mosaicism.

Brain Tumor Pathol 2018 Oct 29;35(4):202-208. Epub 2018 Aug 29.

Department of Pathology, Duke University Medical Center 3712, Davison Building, Durham, NC, 27710, USA.

Ollier disease (OD) and Maffucci syndrome are rare conditions due to a post-zygotic somatic mutation that results in mosaicism. In addition to enchondromas and hemangiomas, some of these patients also develop other unrelated tumors, such as gliomas, that harbor IDH mutations, suggesting that an IDH mutation is a common genetic event in the tumorigenesis in this group of patients. We illustrate an interesting case of multifocal IDH-mutant astrocytomas in an OD patient with 8 years of follow-up. Read More

The role of metabolic enzymes in mesenchymal tumors and tumor syndromes: genetics, pathology, and molecular mechanisms.

Lab Invest 2018 04 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

Mutational analysis using Sanger and next generation sequencing in sporadic spindle cell hemangiomas: A study of 19 cases.

Genes Chromosomes Cancer 2017 12 23;56(12):855-860. Epub 2017 Sep 23.

Department of Pathology, Radboud University Medical Centre, Nijmegen, The Netherlands.

Spindle cell hemangioma (SCH) is a distinct vascular soft-tissue lesion characterized by cavernous blood vessels and a spindle cell component mainly occurring in the distal extremities of young adults. The majority of cases harbor heterozygous mutations in IDH1/2 sporadically or rarely in association with Maffucci syndrome. However, based on mosaicism and accordingly a low percentage of lesional cells harboring a mutant allele, detection can be challenging. Read More

Tumor Syndromes That Include Bone Tumors: An Update.

Surg Pathol Clin 2017 Sep;10(3):749-764

Department of Medical Genetics and Skeletal Rare Diseases, Rizzoli Orthopedic Institute, Via Pupilli 1, Bologna 40136, Italy.

Tumor syndromes, including bone neoplasias, are genetic predisposing conditions characterized by the development of a pattern of malignancies within a family at an early age of onset. Occurrence of bilateral, multifocal, or metachronous neoplasias and specific histopathologic findings suggest a genetic predisposition syndrome. Additional clinical features not related to the neoplasia can be a hallmark of specific genetic syndromes. Read More

Constitutional abnormalities of IDH1 combined with secondary mutations predispose a patient with Maffucci syndrome to acute lymphoblastic leukemia.

Pediatr Blood Cancer 2017 Dec 24;64(12). Epub 2017 May 24.

Department of Pediatrics, St. Luke's International Hospital, Tokyo, Japan.

Maffucci syndrome is a nonhereditary disorder caused by somatic mosaic isocitrate dehydrogenase 1 or 2 (IDH1 or IDH2) mutations and is characterized by multiple enchondromas along with hemangiomas. Malignant transformation of enchondromas to chondrosarcomas and secondary neoplasms, such as brain tumors or acute myeloid leukemia, are serious complications. A 15-year-old female with Maffucci syndrome developed B-cell precursor acute lymphoblastic leukemia (BCP-ALL). Read More

The association of enchondromatosis with malignant transformed chondrosarcoma and ovarian juvenile granulosa cell tumor (Ollier disease).

Taiwan J Obstet Gynecol 2017 Apr;56(2):253-257

Gynecologic Oncology Center, Department of Obstetrics and Gynecology, First Faculty of Medicine, Charles University and General University Hospital in Prague, Czech Republic. Electronic address:

Objective: Ovarian juvenile granulosa cell tumor has an interesting association with multiple enchondromatosis (Ollier disease and Maffucci syndrome) and should be considered a leading diagnosis when an ovarian mass is found in young patients with these conditions. Besides the association with nonskeletal malignancies, there is a high risk of malignant transformation of enchondroma in chondrosarcoma as was also the case in this instance.

Case Report: The report uses multiple images to document the representative and characteristic markers of multiple enchondromas in a 22-year-old patient with Ollier disease complicated by malignant transformation of chondrosarcoma and in whom the disease is associated with ovarian juvenile granulosa cell tumor of the right ovary.
