It accounts for 60% - 70% of malignant mesenchymal tumors and 5% of pediatric cancers. Two-thirds of these cancers are diagnosed in children under 6 years of age, with a slight male predominance. Materials and Methods: This is a retrospective descriptive study of 10 cases of RMS collected in the pediatric hematology and oncology department of the Oujda university hospital, over a 5-year period, running from January 2018 to December 2022. Results: The median age at diagnosis was 3 years, with a sex ratio of 1. The mean time to diagnosis was 2 months. The most common site was the head and neck (50%), followed by the genitourinary tract (20%), the extremities (20%) and finally the abdomen (10%). The most frequent mode of discovery was a mass or swelling found in 90% of patients (all sites included), followed by exophthalmos in 30% of cases. At the diagnostic stage, CT scans were performed in 70% of cases and MRI in 5 patients (50%). Histological diagnosis was determined by immunohistochemical pathology in all our patients, with a predominance of embryonal (70%) versus alveolar (20%) and spindle cell types (10%). All patients underwent an extension workup, and a cervico-thoraco-abdominopelvic CT was performed in all patients (100%);MRI was performed in 2 patients (20%);lymph node involvement was present in 5 patients (50%). Metastases at the time of diagnosis were noted in only 1 patient (10%), who simultaneously presented with two metastatic sites;testicular and abdominal wall. Sixty percent of patients presented with advanced disease (high risk) and 40% with standard risk. Chemotherapy was used in all patients (100%), with upfront tumor resection performed in 40%. Fifty percent of patients received radiotherapy at a mean dose of 43 Gy, with the orbit the most frequently irradiated area (30%). All patients underwent CTscan and/or MRI and/or ultrasound surveillance. Follow-up during and after treatment was marked展开更多

Respiratory distress often occurs during the neonatal period, and in 80% to 85% of cases, the diagnosis is made before the age of 2 years following respiratory infections. Case Report: We report a case of MAKC diagnosed in the neonatal period. The diagnosis was based on clinical, radiological and histological elements. Our patient underwent surgical resection. Histological examination confirmed the diagnosis of MAKC without any sign of malignancy. The postoperative evolution was good. Conclusion: Clinicians and pathologists should recognize the early discovery of MAKC in neonatal age. The clinical diagnosis strongly guided by the radiological approach is confirmed by the pathological anatomy insofar as the therapeutic sanction is surgical in the majority of the cases.展开更多

The diagnosis, evoked in front of swelling, a parietal pain, supported on the tomodensitometry, rests on the anatomopathological examination. The treatment is based on the combination of chemotherapy surrounding complete surgical removal of the tumor. Radiotherapy should remain reserved for a few specific indications because of its complications. We report the case of three children who presented with a pleural effusion revealing Ewing’s sarcoma affecting the ribs.展开更多
