Résumé

L’ostéosarcome extra-squelettique est un rare sarcome des tissus mous survenant habituellement au niveau des cuisses et des fesses. Son diagnostic clinique est difficile. Les signes radiologiques sont importants pour confirmer l’origine de la tumeur au niveau des tissus mous. La clé du diagnostic est l’examen anatomopathologique avec les mêmes aspects morphologiques décrits au niveau de l’ostéosarcome osseux. Nous rapportons le cas d’un homme de 64 ans qui a présenté une tumeur récidivante de la cuisse droite. Les examens radiologiques ont montré une large masse des tissus mous enchâssée au niveau de la graisse hypodermique. A travers cette observation nous allons décrire cette tumeur rare et nous allons discuter ces caractéristiques anatomopathologiques, cliniques, radiologiques et thérapeutiques.

Abstract

Extraskeletal osteosarcoma is a rare soft tissue sarcoma that arise commonly in the thigh and buttock. This clinical diagnosis is difficult. Radiological funding is important to confirm the soft tissue origin of the tumor. The key of diagnosis is the pathological pattern with the same morphological funding in bone osteosarcoma.We describe a 64 years old men how presented a recurrent mass of the right hip. The radiological examination showed a large soft tissue mass enchaced in the subcutaneous flat. Pathological examination confirmed the diagnosis of extraskeletal osteosarcoma. We aimed with this observation to describe this rare tumor and to discuss these pathological, clinical, radiological and therapeutic features.
