Le chondrosarcome de la main. Discussion diagnostique et thérapeutique (à propos de trois cas)

Chondrosarcoma in the distal phalanx of index finger: Clinical report and literature review

“…As a general rule, incisional biopsy before definitive procedure is desirable but we believe that in some circumstances [16], as in our case, it is possible to plan a radical procedure when X-ray and MRI clearly show a locally aggressive lesion. Surgical treatment for hand chondrosarcoma should be decided case by case trying to preserve hand function and considering: that the lesion is locally aggressive with minimal metastatic potential; the appearance of the lesion in X-ray pictures and MRI scan (tumour size-cortical bone aspect); the residual functional impairment in case of amputation or ray resection procedure.…”

Les chondrosarcomes de la main

“…La résonance magnétique nucléaire permet d'étudier la lésion et son extension en étudiant la matrice cartilagineuse : en T1 elle est en hyposignal, en T2 elle est en hypersignal, les zones calcifiées restent en hyposignal [11]. La scintigraphie montre une hyperfixation osseuse et n'a pas d'intérêt particulier dans cette pathologie.…”

“…Le chondrosarcome est une tumeur maligne cartilagineuse très rare au niveau de la main et ne représente que 4 % de l'ensemble des tumeurs malignes et de 1 à 1,5 % des chondrosarcomes du squelette entier [3,11,17,21,24,26,27,40]. Cette tumeur est primitive ou survenant sur une lésion préexistante (chondrome) [8,25,32].…”

Arthroscopic Excision of an Intra-Articular Osteochondroma of the Knee

“…Solitary osteochondroma appears as a cartilage-capped osseous projection featured from the surface of the bone. The tumor usually is located extra-articularly mainly in the proximal humerus, the distal femur, or the proximal tibia [1][2]5]. Osteochondroma is usually asymptomatic and when clinical symptoms are present these might be as a result of traumatic contusion or pressure on adjacent muscles, joints, nerves, or blood vessels [6].…”
