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.

Enchondromas in olliers disease present a risk of malignant transformation into chondrosarcomas. Cortical erosion, pathological fracture and extension of the tumor into soft tissues can be considered as a sign of malignancy. Surgery is performed in cases of complications and malignant transformation.

Multiple Enchondromatosis: Olliers Disease- A Case Report

The inheritance pattern of Ollier disease is unknown but is thought to not be simply a Mendelian pattern. Mutations were absent in DNA isolated from the blood, muscle, or saliva of the subjects. Samples from multiple tumors range, ; mean, 2. With the exception of Ollier disease, in which PTHR1 mutations are found in a very small subset of patients, the responsible genes for these extremely rare syndromes are so far unknown.



Enchondromas are benign cartilaginous tumors that develop in the metaphysis and may become in-corporated into the diaphysis in close proximity to the growth plate enhcondromatosis. In enchondromas and chondrosarcomas from 31 enchondromatosis patients Ollier disease or Maffucci syndrome, lacking platyspondyly from 3 different European countries, Rozeman et al. The etiology of enchondromatosis has been associated with post-zygote state mutations during development.

Achondrogenesis type 1B Autosomal recessive multiple epiphyseal dysplasia Atelosteogenesis, type II Diastrophic dysplasia. Microscopically, the lesions can be more cellular and cytologically atypical as compared to solitary enchondroma.

The diagnosis is mainly based on clinical, histological and radiological evaluation. Otro caso de discondrosteosis generalizada congenita, tipo Ollier. Osteoporosis What is Osteoporosis?

Magnetic resonance imaging demonstrates lobulated lesions with intermediate signal intensity on T2- weighted enchohdromatosis and predominantly high signal intensity on T2- weighted sequences.

Articles from Journal of Clinical and Diagnostic Envhondromatosis Olliers disease and maffucci syndrome are usually non-familial disorders [ 3 ]. Clinical behaviour is determined by size, number, location and evolution of enchondromas, age of onset and of diagnosis.

Olliers disease is characterized by the presence of at least three enchondromas [ 1 ]. Similar lesions are seen in the greater trochanter of the right femur. Enchondromatomosis with severe platyspondyly in enchondomatosis brothers.

There is an increased risk of development of malignant tumors. Enchondromas are common benign cartilage tumors of bone.

Halal and Azouz added 3 tentative categories to the 6 in the classification of Spranger et al. This rare combination is known as metachondromatosis. The diagnosis of Maffucci’s syndrome was mu,tiple. Looking For More References?

Jordan Mahafza reported on a year-old female patient, diagnosed with Ollier’s Disease since the age of 9-years, who presented with a 5-month history of progressive right limb weakness and diplopia provoked by left lateral gaze.
