Journal Title: Interventions in Pediatric Dentistry Open Access Journal - Year 2018, Vol 1, Issue 3
Abstract
Ewing’s sarcoma (ES) is a malignancy primarily affecting bone tissue that is commonly diagnosed in adolescents and young adults. Its occurrence in the head and neck region is unusual and generally involves the mandible and maxilla. We report here a case of Extraskeletal Ewing’s sarcoma (EES) of the Parapharangeal space in a 20 year-old female who presented with blurred vision, dysphasia. CT examination showed a large, seemingly well-defined soft tissue mass in the left side of face involving parapharyngeal space with intracranial extension. The patient undergone chemotherapy and radiotherapy. A review of the literature revealed only one previous reports of EES occurring in the parapharyngeal space. Extraskeletal Ewing’s sarcoma (EES) is a rare, rapidly growing, round-cell, malignant tumour that can develop in the soft tissues at any location. It was first described by Tefft [1] in four patients who presented with paravertebral soft tissue tumours with histological appearance resembling Ewing’s sarcoma. In a clinicopathological study of 39 cases of EES reported by Angervall et al. [2] the paravertebral region was the most frequent site of involvement, followed by the lower extremity and chest wall. The head and neck region is an unusual primary site for this tumour and, according to Chao [3], there were only five out of 118 cases of EES located in the head and neck region. Herein, we report a case of EES occurring in the left side of face involving parapharyngeal space.
