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.

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.

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.

IDH1 and IDH2 mutations are frequent events in central chondrosarcoma and central and periosteal chondromas but not in other mesenchymal tumours.

J Pathol 2011 Jul 19;224(3):334-43. Epub 2011 May 19.

Department of Histopathology, Royal National Orthopaedic Hospital NHS Trust, Stanmore, Middlesex HA7 4LP, UK.

Somatic mutations in isocitrate dehydrogenase 1 (IDH1) and IDH2 occur in gliomas and acute myeloid leukaemia (AML). Since patients with multiple enchondromas have occasionally been reported to have these conditions, we hypothesized that the same mutations would occur in cartilaginous neoplasms. Approximately 1200 mesenchymal tumours, including 220 cartilaginous tumours, 222 osteosarcomas and another ∼750 bone and soft tissue tumours, were screened for IDH1 R132 mutations, using Sequenom(®) mass spectrometry.
