Clinical differences between central and peripheral chondrosarcomas.

Bone Joint J 2021 May;103-B(5):984-990

Department of Orthopaedics, Royal Orthopaedic Hospital, Birmingham, UK.

Aims: Chondrosarcoma is the second most common primary sarcoma of bone: conventional chondrosarcoma accounts for 85% of all cases. Conventional chondrosarcoma may be central or peripheral. Most studies group central and peripheral chondrosarcomas together, although there is growing evidence that their clinical behaviour and prognosis differ. Read More

Monomelic Maffucci syndrome.

BMJ Case Rep 2021 Mar 3;14(3). Epub 2021 Mar 3.

Trauma and Orthopaedics, Southport and Ormskirk Hospital NHS Trust, Southport, UK.

Maffucci syndrome is a rare congenital, non-hereditary condition characterised by presence of multiple enchondromas and haemangiomas. Enchondromatous lesions affecting epiphysial growth plates can lead to angular deformities and leg-length discrepancy in the lower limb. We describe a 12-year-old girl with monomelic Maffucci syndrome affecting her left lower limb. Read More

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 Feb 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 Apr 12;51(4):536-545. Epub 2020 Nov 12.

Somatic Mosaicism of IDH1 R132H Predisposes to Anaplastic Astrocytoma: A Case of Two Siblings.

Front Oncol 2019 14;9:1507. Epub 2020 Jan 14.

Center for Genetic Medicine, Children's National Health System, Washington, DC, United States.

Anaplastic astrocytomas are aggressive glial cancers that present poor prognosis and high recurrence. Heterozygous IDH1 R132H mutations are common in adolescent and young adult anaplastic astrocytomas. In a majority of cases, the IDH1 R132H mutation is unique to the tumor, although rare cases of anaplastic astrocytoma have been described in patients with mosaic IDH1 mutations (Ollier disease or Maffucci syndrome).

D-2-Hydroxyglutaric Aciduria with Enchondromatosis and Angiokeratoma Circumscriptum.

Cureus 2019 Nov 14;11(11):e6157. Epub 2019 Nov 14.

Dermatology, Oklahoma University Health Sciences Center, Oklahoma City, USA.

In this study, we report a four-year-old male with D-2-hydroxyglutaric aciduria (D2HA) and enchondromatosis with a prior history of hyperpigmented, segmental whorls and streaks on his abdomen who later presented with an eruption of angiokeratoma circumscriptum within a similar distribution. His condition can likely be explained by underlying somatic mosaicism; however, a unifying culprit gene mutation has not yet been identified.

IDH1 immunohistochemistry reactivity and mosaic IDH1 or IDH2 somatic mutations in pediatric sporadic enchondroma and enchondromatosis.

Virchows Arch 2019 Nov 25;475(5):625-636. Epub 2019 Jun 25.

Division of Clinical Pathology, Molecular Pathology Unit, Geneva University Hospitals, Rue Gabrielle-Perret-Gentil 4, 1211, Geneva, Switzerland.

Mosaic somatic mutations in the isocitrate dehydrogenase 1/2 (IDH1/2) genes have been identified in most enchondromas by targeted mutation analysis. Next-generation sequencing (NGS), that may detect even low-level mosaic mutation rates, has not previously been applied to enchondromas. Immunohistochemistry using the H09 clone is routinely used as a surrogate for the common R132H IDH1 mutation in gliomas. Read More
