Abstract

Mediastinal tumors are the most common thoracic tumor in the pediatric population. They include a spectrum of tumors, and most are malignant. These lesions can be anatomically and radiologically classified by means of compartments; anterior, middle, and posterior. Symptoms, signs, localization of the tumor, age of the child, and tumor markers are key points of diagnosis. Surgical approaches are typically needed for diagnosis, but sometimes tru-cut needle biopsies may be sufficient. Mediastinoscopy, mediastinotomy, and video-assisted thoracoscopic surgery may be used in the diagnostic workup of mediastinal tumors in children as they are used in adults. Frequently, diagnosis and treatment are both established by means of surgery. Surgery remains the mainstay of treatment of most benign and malignant nonlymphoid tumors. Combined modality of treatment incorporating chemotherapy and radiotherapy is often required in malignant tumors and is associated with high survival rates in these patients.
