Conclusion:
Sarcoma and lymphoma comprised 75% of 20 cases of pediatric sinonasal malignancies. As regards treatment, all 20 patients received chemotherapy and 6 patients (30%) underwent surgery. The overall 5-year survival rate was 52%, with favorable outcome for solid tumors compared with lymphoma.
Objective:
We aimed to investigate the clinical features and treatment outcomes of sinonasal malignancies in 20 pediatric patients.
Methods:
Clinical features were evaluated and tumors were staged according to the staging system for each histologic type.
Results:
The 20 patients consisted of 12 males and 8 females, ranging in age from 1 to 16 years, with a median age of 9.6 years at diagnosis. More than half of the patients presented with nasal obstruction as the primary symptom, and mean symptom duration to diagnosis was 5.4 months. Primary tumor sites included the paranasal sinuses alone in four patients, the nasal cavity alone in eight, and both in eight. Eight tumors were sarcomas and seven were lymphomas. The remaining tumors included three olfactory neuroblastomas and two primitive neuroectodermal tumors. The main treatment modality was chemotherapy rather than surgery. The overall survival rate was 52%, and patients with solid tumors survived significantly longer than those with lymphoma (p = 0.02).

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
