Dermatofibrosarcoma protuberans (DFS) is a mesenchymal-origin skin tumor with intermediate malignancy. Though rare, it's not exceptional, comprising about 0.1% of malignant skin tumors.The authors discuss clinical, radiological, histopathological studies, and various therapeutic modalities for this tumor.Our 82-year-old patient presented with a 3 cm swelling on the right arm, initially undergoing biopsy followed by surgical excision of the mass.Adjuvant treatment with radiotherapy or chemotherapy is unnecessary unless recurrence or malignant transformation occurs. Histological analysis is crucial for diagnosis. The preferred treatment method is wide surgical excision.Prognosis primarily depends on malignancy, especially at the local level, with a high risk of recurrence. It's rare for a distinctly malignant sarcomatous transformation with metastasis to occur.

Osteoarticular tuberculosis (OAT) is defined by the set of pathological manifestations secondary to the attacks of osteoarticular structures of the locomotor system by the Bacillus of Koch (BK). We report a case of tuberculosis of the navicular bone, which is a rare location of OAT, on a female patient who consulted for chronic pain (mixed appearance) evolving for more than 7 years and for whom we realized a radiological assessment based on standard radiography and magnetic resonance imaging and a biological assessment. The foot is rarely involved, accounting for about 10% of cases of osteoarticular tuberculosis. The diagnosis is often made at a late stage because osteoarticular tuberculosis is paucibacillary, and it is difficult to isolate or culture Koch's bacillus. Clinical manifestations are aspecific; pain and joint swelling are the 2 usual signs. Pain may be mechanical, inflammatory, or mixed. The standard radiography allows first to orient the diagnosis by the demonstration of a lytic process; a biological inflammatory syndrome and the magnetic resonance imaging allow to give more arguments in favor, then the biopsy comes to confirm the diagnosis. Tuberculosis of the navicular bone is a rare localization of OAT; its diagnosis is the same as well as the treatment.

Isolated acute dislocation of the distal radioulnar joint is a rare lesion, and in 50 % of cases goes unrecognized; it may be palmar or dorsal. Its diagnosis is suspected when the wrist is traumatic, painful, with limited pronosupination and no fracture on radiological examination. Treatment is aimed at preventing the development of chronic instability and/or arthrosis, and consists of reduction followed by immobilization.

Posterior shoulder fracture-dislocation is a rare injury accounting for approximately 0.9% of shoulder fracture-dislocations and often misdiagnosed during the initial presentation to a physician. Though the reverse Hill-Sachs lesion is a common injury associated with posterior shoulder dislocation, the associated scapula fracture represents only 6% of the lesions associated with a posterior dislocation of the shoulder. We report the case of a neglected posterior shoulder dislocation with a reverse Hill-Sachs lesion treated by filling with an autologous graft associated with an extra articular fracture of the scapula fixed by a plate and a posterior bone end-stop because of the posterior instability. After two years of follow-up, the patient has no episode of dislocation and is satisfied with the functional result with a constant score of 68/100 points.

La luxation traumatique invétérée de la hanche est une affection rare et grave avec une prise en charge difficile et non encore codifiée. L'arthroplastie totale de la hanche reste le traitement chirurgical de choix. Nous rapportons un cas de luxation iliaque invétérée de la hanche chez un jeune patient de 19 ans, traitée par une arthroplastie totale de la hanche. Après un recul de 2 ans, le résultat fonctionnel est satisfaisant, avec une marche indolore sans aide. Le Score de Harris est de 96 et le score de Merle d'aubigné-Postel est de 17.

L'offset fémoral est l'élément pronostic le plus important dans l'arthroplastie de la hanche. Sa restauration est devenue de plus en plus une obligation. Toute modification de la valeur native de l'offset retenti sur la qualité du fonctionnement clinique de la hanche. Le but de notre travail était d'évaluer le fonctionnement clinique de la hanche en fonction de la valeur de l'offset fémoral après une arthroplastie. C'est une étude rétrospective effectuée entre 2010 et 2013, comportant 27 patients ayant bénéficiés d'une arthroplastie totale de la hanche. Les patients ayant eu un geste chirurgicale antérieur sur la même hanche ou sur la hanche controlatérale ont été exclus. Les mesures ont été effectuées sur des radiographies standards de la hanche en rotation interne d'environ 15, avec un agrandissement à 100%. Les résultats cliniques étaient évalués au moyen du score de WOMAC qui était en moyenne de 15,2 points, et le score de Merle d'Aubigné-Postel avec une moyenne de 15 points. Deux autres tests ont été évalués dans notre étude qui sont le step et le hop test. Les meilleurs résultats fonctionnels ont été obtenus chez les patients ayant eu une latéralisation de la tige fémoral avec un offset augmenté.

Giant squamous cell carcinomas (SCC) larger than 5 cm in diameter are uncommon; there is no guideline on the size of an SCC that is considered giant. Treatment may be difficult with the need for large tissue resections and complex surgical reconstruction. We report a rare case of giant squamous cell carcinoma of the shoulder attached to deep anatomic planes. The entire mass was removed, resulting in a large defect that was repaired with myocutaneous flap rotation of the latissimus dorsi. Three courses of radiotherapy were performed after surgery. Fifteen months after the operation, the patient is well and working without any local recurrence and metastasis. [ABSTRACT FROM AUTHOR]

Hormis le déficit fonctionnel engendré par la scapuléctomie élargie, la majorité des tumeurs malignes de l'épaule relèvent actuellement d'un traitement conservateur. Plusieurs procédures de reconstruction ont été décrites dernièrement, on cite les prothèses totales et les techniques de reconstruction par allogreffe. Dans ce travail nous allons exposer nos résultats et mettre le point sur les différents aspects thérapeutique de cette chirurgie notamment ses indications ses complications et ses résultats. Nous rapportons une étude rétrospective de 9 patients opérés entre 1996 et 2010. A partir des dossiers médicaux, nous avons recueilli les données concernant les manifestations cliniques, les résultats de l'imagerie, la prise en charge thérapeutique, les résultats histologiques et le suivi à cours et à moyen terme. La durée moyenne du suivi était de 33 mois avec des extrêmes allant de neuf à 132 mois. Le suivi consistait à évaluer les résultats fonctionnels et oncologiques selon le système Enneking et le score MSTS. Ainsi, le résultat fonctionnel était bon chez 5 patients, moyen chez un seul patient et mauvais chez trois patients; deux patients ont présenté des récidives tumorales ayant nécessité une reintervention. Les techniques de scapuléctomie nécessitent une bonne stratégie thérapeutique basée sur une étude approfondie de l'imagerie, une bonne connaissance de l'anatomie locale et avant tout, une sélection rigoureuse des patients.
