Background:Myopericytoma (MPC) is term that describe a rare group of perivascular tumours of soft tissue and show a range of histological growth patterns. Only a few cases describing MPC have been reported. Aims: To document and investigate the clinical and histopathological characteristics and differential diagnosis of myopericytoma. Patients/methods: The present study reports a unique case of myopericytomas found in the 2nd and 3rd inter-toe spaces of a 54-year-old patient. Results: a 54 year old female patient, presents in our department for a painless mass on the dorsal surface of the right forefoot of progressive installation over 2 years.The mass was firm, non pulsatile and mobile, with no sign of inflammation, evolving in a context of conservation of the general state. The X-ray of the right forefoot did not reveal any notable bone abnormality. An MRI was subsequently performed, which objectified an infiltrating tumor mass of probable sarcomatous origin. The mass was excised surgically, and a pathological and immunohistochemical examination was performed afterward, the diagnosis of myopericytoma was confirmed. No recurrence was found in the follow-up of 12 months. Conclusions: MPC is a rare and mostly benign tumor that presents as spindle cells in a concentric perivascular growth model with an immunohistochemical staining positive for smooth muscle actin. Local recurrences and rarely metastases may occur in atypical and malignant neoplasms.
The Luxatio erecta humeri is the inferior dislocation of the glenohumeral joint and the poterior hip dislocation are rare cases in the emergency department. The association of the two presentations is a rare entity and similar cases are very little found in the literature, hence the purpose of this work. We report the case of a 35-year-old taxi passenger victim of a public road accident who presented with both luxatio erecta humeri and pure posterior hip dislocation. An orthopaedic surgeon reduced the luxatio erecta humeri and the posterior hip dislocation under procedural anesthesia as soon as the patient’s vital signs were stable. Different concomitant injuries and various injury mechanisms have been described in regard to inferior shoulder dislocation in the literature. However, pure posterior dislocation of the hip as a concomitant distant region injury for luxatio erecta humeri is being described for the first time in this case report. Some authors suggested that a two-step manoeuver can be easier to practice than a one-step manœuvre, in our specific case, luxatio erecta was easily reduced by a single operator in a single attempt. Luxatio erecta humeri and posterior hip dislocation are lesions that occur at high energy and complex injuries can accompany them in patients with multiple traumas. A two-step closed reduction can be easily applied by a single operator under procedural anesthesia. hip and shoulder dislocations are extreme emergencies.
Les luxations traumatiques de l'articulation de l'épaule sont généralement décrites comme des luxations antéro-inférieures. Les luxations antéro-supérieures sont extrêmement rares. Nous rapportons un cas rare de luxation traumatique de l´épaule antéro-supérieure chez un patient âgé de 45 ans où l´examen physique trouve une saillie antéro-supérieure de la tête humérale en sous-cutanée avec comblement de l´espace sous acromiale, le diagnostic était confirmé radiologiquement avec la découverte d´une rupture totale des tendons supra-épineux et sous scapulaire à l´imagerie par résonance magnétique. L´épaule était jugée instable après réduction de la luxation. Une arthrorise gléno-humérale provisoire était réalisée par la suite avec des bons résultats fonctionnels.
