Rare Presentation of Pediatric Multiple Enchondromatosis Limited to Single Ray or Single Nerve Distribution in the Hand: A Multicenter Case Series.

J Pediatr Orthop 2022 May 17. Epub 2022 May 17.

Norton Children's Hospital, Louisville, KY.

Background: Multiple enchondromas in the pediatric hand is a relatively rare occurrence and the literature regarding its incidence and treatment is sparse. Within this rare subset of patients, we identified a unique cohort in which lesions are confined to multiple bones in a single ray or adjacent rays within a single nerve distribution. We review the clinical and pathologic characteristics and describe the indications for and outcomes of treatment in this unique subset of patients as well as offer conjectures about its occurrence.

Juvenile granulosa cell tumor associated with Ollier disease.

Skeletal Radiol 2022 Mar 16. Epub 2022 Mar 16.

Department of Radiology, Mayo Clinic, 200 First Street SW, Rochester, MN, 55905, USA.

Prior case reports have described synchronous ovarian juvenile granulosa cell tumor (JGCT) and enchondromatosis in patients with Ollier disease and Maffucci syndrome. We present a case of a juvenile granulosa cell tumor with an IDH1 somatic mutation identified in the ovarian tissue in a 15-year-old female who presented with abnormal vaginal bleeding, several months of irregular menses, and a large multicystic adnexal mass. Multiple mixed lytic and sclerotic lesions were identified in the bones of the pelvis on imaging studies obtained during the work-up of her abdominal mass. Read More

Cell-free DNA from plasma as a promising alternative for detection of gene mutations in patients with Maffucci syndrome.

Hereditas 2022 Jan 18;159(1). Epub 2022 Jan 18.

Department of Interventional Therapy, Multidisciplinary Team of Vascular Anomalies, Shanghai Ninth People's hospital, Shanghai Jiao Tong University, Shanghai, People's Republic of China.

Maffucci syndrome (MS, OMIM 166000) is an extremely unusual, nonhereditary, multisystemic disorder that is characterized with multiple enchondromas and vascular lesions, most of which are spindle cell hemangiomas. Complications of MS, such as bone deformities and dysfunction caused by enchondromas, usually increase during childhood and adolescence. Malignant transformation of enchondromas and other malignancies are the most severe complications. Read More

IDH1 R132C and ERC2 L309I Mutations Contribute to the Development of Maffucci's Syndrome.

Front Endocrinol (Lausanne) 2021 1;12:763349. Epub 2021 Nov 1.

Department of Nephrology, Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Background: Maffucci's syndrome is characterized by the coexistence of multiple enchondromas and soft-tissue hemangiomas. It has been clear that somatic mosaic isocitrate dehydrogenase type 1 (IDH1) or isocitrate dehydrogenase type 2 (IDH2) mutations are associated with Maffucci's syndrome and Ollier disease, but the mechanisms underlying hemangiomas of the Maffucci's syndrome is still obscure. This study aimed to determine the mechanism of hemangiomas in Maffucci's syndrome. Read More

Department of Oral and Maxillofacial Surgery, Nagoya University Hospital, Nagoya, Japan; Department of Oral and Maxillofacial Surgery, Nagoya University School of Medicine, Nagoya, Japan.

Maffucci syndrome, first described in 1881, is a rare, non-hereditary skeletal disorder characterized by multiple enchondromas in combination with soft tissue hemangiomas. Recent studies have implicated somatic mutations in IDH1/2 contributing to the pathogenesis of Maffucci syndrome. This study describes the first case of Maffucci syndrome harboring a mutation in IDH1, which was associated with a hemangioma in the oral mucosa. Read More

Somatic variant (p.R132C) in an adult male with Maffucci syndrome.

Cold Spring Harb Mol Case Stud 2021 12 9;7(6). Epub 2021 Dec 9.

Murdoch Children's Research Institute, Melbourne, Parkville, Victoria, Australia 3052.

Maffucci syndrome is a rare, highly variable somatic mosaic condition, and well-known cancer-related gain-of-function variants in either the or genes have been found in the affected tissues of most reported individuals. Features include benign enchondroma and spindle-cell hemangioma, with a recognized increased risk of various malignancies. Fewer than 200 affected individuals have been reported; therefore, accurate estimates of malignancy risk are difficult to quantify and recommended surveillance guidelines are not available.

Department of Orthopaedics and Traumatology, Lithuanian University of Health Sciences, Kauno klinikos, Kaunas, Lithuania.

Summary Background: Ollier disease is the most common nonhereditary type of enchondromatosis. Enchondromas are common, usually benign intraosseous cartilaginous tumors that form near the growth plate cartilage predominantly unilaterally in the metaphyses and diaphyses of tubular bones. They usually affect the long bones of the hand, the humerus, and the tibia, followed by flat bones, such as the pelvis. Read More

Update on the imaging features of the enchondromatosis syndromes.

Skeletal Radiol 2022 Apr 24;51(4):747-762. Epub 2021 Jul 24.

Imaging Department, Royal National Orthopaedic Hospital, Stanmore, UK.

Ollier disease and Maffucci syndrome are the commonest enchondromatosis subtypes, arising from non-hereditary mutations in the IDH1 and IDH2 genes, presenting in childhood and being characterised by multiple enchondromas. Maffucci syndrome also includes multiple soft tissue haemangiomas. Aside from developing bony masses, osseous deformity and pathological fracture, ~ 40% of these patients develop secondary central chondrosarcoma, and there is increased risk of non-skeletal malignancies such as gliomas and mesenchymal ovarian tumours.

CT angiography and MRI of hand vascular lesions: technical considerations and spectrum of imaging findings.

Insights Imaging 2021 Feb 12;12(1):16. Epub 2021 Feb 12.

Service D'imagerie Guilloz, CHRU Nancy, 54 000, Nancy, France.

Vascular lesions of the hand are common and are distinct from vascular lesions elsewhere because of the terminal vascular network in this region, the frequent hand exposure to trauma and microtrauma, and the superficial location of the lesions. Vascular lesions in the hand may be secondary to local pathology, a proximal source of emboli, or systemic diseases with vascular compromise. In most cases, ischaemic conditions are investigated with Doppler ultrasonography. Read More

Enchondromatosis and Growth Plate Development.

Curr Osteoporos Rep 2021 02 11;19(1):40-49. Epub 2020 Dec 11.

Department of Orthopaedic Surgery, Duke University School of Medicine, Durham, NC, 27710, USA.

Purpose Of Review: Enchondroma is a common cartilage benign tumor that develops from dysregulation of chondrocyte terminal differentiation during growth plate development. Here we provide an overview of recent progress in understanding causative mutations for enchondroma, dysregulated signaling and metabolic pathways in enchondroma, and the progression from enchondroma to malignant chondrosarcoma.

Recent Findings: Several signaling pathways that regulate chondrocyte differentiation are dysregulated in enchondromas. Read More

Basophil activation test for Staphylococcus aureus enterotoxins in severe asthmatic patients.

Clin Exp Allergy 2021 04 12;51(4):536-545. Epub 2020 Nov 12.

Department of Translational Medical Sciences, University of Campania "Luigi Vanvitelli", Naples, Italy.

Background: Several studies have shown an association between severe asthma and serum immunoglobulins E (IgE) against Staphylococcus aureus enterotoxins (SEs). SEs-the prototypes being types A (SEA), B (SEB) and toxic shock syndrome toxin 1 (TSST-1)-can induce both polyclonal and specific IgE responses.

Mutant IDH1 favours the production of 2-hydroxyglutarate, an oncometabolite with multiple downstream effects which promote tumourigenesis. mutations have been described in a number of neoplasms most notably low-grade diffuse gliomas, conventional central and periosteal cartilaginous tumours and cytogenetically normal acute myeloid leukaemia.
