“…Imaging evaluation required in monitoring the disease. Computed tomography is used to monitor bone destruction and mass propagation fields, while MRI is an ideal method for the evaluation of soft tissue involvement around the primary lesion [12]. In this case, a suspicious residual lesion was detected in the left maxillary sinus with evidence of bony resorption in the medial wall of maxillary sinus showed in repeated CECT.…”

Background: Ewing sarcoma is a malignant round cell neoplasm and categorized as part of Ewing family tumor (EFT). Only 1-4% of all Ewing sarcomas are primarily located in the head and neck region and the isolated primary sinonasal sarcoma represents a rare entity. This case was reported due to its rarity and dilemma in diagnosis of recurrent post-treatment. Case presentation: We report a rare case of isolated left maxillary sinus Ewing sarcoma, presented with frequent unprovoked epistaxis, nasal blockage, and rhinorrhea from the left nostril for more than 2 years. Histopathological and immunohistochemical studies performed on the tissue taken from the left nasal mass confirmed Ewing sarcoma. He responded well to the 9 cycles of chemotherapy, evidenced by regression of mass from repeated CECT. However, the post-treatment scan showed multifocal nodular mucosal thickening involving the medial, anterior, and lateral walls of the maxillary sinus with corresponding bony resorption of the medial wall, raising a suspicion of residual disease. As such, he underwent endoscopic medial maxillectomy, which intraoperative findings revealed mild thickening of normal mucosa within the left maxillary sinus and histopathological examination showed no evidence of malignant cell. He showed no signs of recurrence during subsequent follow-up. Conclusion: As a conclusion, in a case of suspicious residual or recurrent disease detected post-chemotherapy, MRI is an option to differentiate between mucosal thickening and residual tumor. However, the role of surgical resection is equally important in assisting the tissue diagnosis and ensures a better local control, perhaps can increase the survival rate.

Introduction: Ewing’s sarcoma is a malignant, small, round, blue-cell tumour with metastatic potential that usually occurs in older children and young adults. Its occurrence in the jawbones is exceedingly rare and even rarer the in mandibular condyle. This case is being reported due to the extreme unique imaging finding of Ewing’s sarcoma arising in the mandible in a young male. Observation: A 22-year-old healthy male presented with a complaint of a progressive swelling in his right preauricular region. Magnetic resonance imaging showed a hyperintense lesion with the right ramus with loss of fat planes. True cut biopsy and histopathological examination of the lesion was suggestive of Ewing’s Sarcoma. Immunohistochemical analysis confirmed the diagnosis. Discussion: The most common presenting symptom of Ewing’s sarcoma in the head and neck region is a rapidly growing expansile mass along with pain, paraesthesia, and visual disturbances often mimicking odontogenic infections. Higher imaging modalities play a major role in the evaluation of the extent of the lesion and diagnosis. Conclusion: Prompt and pertinent treatment planning is critical for appropriate and timely management.
