Enchondromatosis is a rare heterogeneous skeletal disease characterized by multiple enchondromas, and it includes several different subtypes of which Ollier . Enchondromas are common benign cartilage tumors of bone. They can occur as solitary lesions or as multiple lesions in enchondromatosis. Enchondromatosis, also known as Ollier disease (see Terminology section), is a non-hereditary, sporadic, skeletal disorder characterised by multiple.

J Bone Joint Surg Am. One tumor in subject 21 harbored a mutation causing an RS substitution, whereas the second tumor had wildtype sequences. The mutation RC was heterozygous and was found in enchondroma specimens from 2 of 6 individuals with Ollier enchondromatosis. The patient presented with various deformations and enchondrkmatosis of the limbs since the age of three years.

Generalized enchondromatosis in a boy with only platyspondyly in the father. C ] – Ovarian mutliple granulosa cell tumor with precocious pseudopuberty Radiology – Enchondromata Inheritance -? Cortical erosion, pathological fracture and extension of the tumor into soft tissues can be considered as a sign of malignancy. The authors thus suggested that the mutations occurred during development, resulting in genetic mosaicism in these individuals.

The literature review of ollier disease.

Multiple enchondromatosis (Ollier disease)

Case 1 Case 1. Surgical intervention is necessary in case of pathological fractures, growth defect and malignant transformation [ 1 ]. The inheritance pattern of Ollier disease is unknown but is thought to not be simply a Mendelian pattern.

The enchondromatosis syndrome includes Ollier diseaseMaffucci syndromespondyloenchondromatosis, metachondromatosis and generalized enchondromatosis. However, there was a case reported by Robinson et al which showed autosomal dominant inheritance of spondyloenchondrodysplasia.

The clinical features of enchondromatosis depend upon the extent of disease and ranges from few small lesions to multiple, widely distributed lesions causing marked skeletal deformation. There was shortening of right leg which was noticed by the parents since 3 years of age. Expert curators review the literature and organize it multille facilitate your work.



Treatment Treatment depends on the type of enchondromatosis; it may include surgery, amputation, bone grafting and sclerotherapy. Vaz and Turner described a case of Ollier disease associated with ovarian juvenile granulosa cell tumor and precocious pseudopuberty. Anteroposterior radiograph of the pelvis showing columnar, radiolucent lesions in the right ilium extending to the crest and suggestive of cartilaginous rests.

Spondyloepiphyseal dysplasia congenita Multiple epiphyseal dysplasia Otospondylomegaepiphyseal dysplasia. Articles from Journal of Clinical and Diagnostic Research: Radiographic findings typically are long low-density streaks projecting through the diaphyses into the epiphyses of the long bone. You can help Wikipedia by expanding it. A bonus to all MIMmatch users is the option to sign up for updates on new gene-phenotype relationships.

Nara Sobreira – updated: Introduction to Bone Biology: This has resulted in deformity of the fourth finger. Hemangiomas, other cutaneous manifestations, and abnormalities in visual acuity, color vision, and sensory parameters were not detected.

The tubular bones of the hand appear globular due to expansion. Fibromuscular dysplasia of intracranial arteries in a patient with enchondromas Ollier disease. Eight tumor samples had subthreshold peaks at the position in IDH1 expected to encode mutations resulting in RC or RH substitutions and mutations were confirmed in 7 of these tumors by the hydrolysis probe assay.

It should be emphasized that enchondromatosis has a mostly unilateral monomelic distribution. Case 4 Case 4. If only a few bones are involved, then little if any handicap is present, although the affected bones do have a higher rate of fracture. This article about a neoplasm is a stub. Unable to process the form. Please consider making a donation now and again in the future. The diagnosis is based on clinical and conventional radiological evaluations. Occasionally patients will also be afflicted with multiple osteochondromas.


Maffucci Syndrome is another form of the disease, characterized by the association of the multiple enchondromas with soft tissue hemagioma. Is it all in the genes? To contribute with your findings to the content of this record, please fill the CTGA Database Information Submission Form and email it, along with supportive documents, to cags emirates. This rare combination is known as metachondromatosis. However, 2 tumors with wildtype sequences from a subject with Maffucci syndrome had high levels of 2HG, and the third tumor with wildtype sequences, from a subject with multiple tumors subject 2had low levels of 2HG.

Enchondromas in olliers disease present a risk of malignant transformation into chondrosarcomas. Two peculiar types of enchondromatosis.

National Center for Biotechnology InformationU. As there was a bony prominence obstructing the pelvic canal, and she declined elective Cesarean section, controlled rupture of membranes was done. These lesions were located one in the right parasagittal frontal lobe and the other infiltrating the brain stem. Some authors make a distinction between Ollier disease and enchondromatosis on the basis of distribution. When malignancy is suspected, the histopathology investigation is used for grading because different grade requires different management [ 2 ].

Case Report A year-old female patient presented to our hospital with difficulty in walking, leg pain and multiple swellings in hands and leg for 2 years.
