OBJECTIVE: Esthesioneuroblastoma is a rare, malignant neoplasm arising from the olfactory neuroepithelium in the upper nasal cavity. Even more rare is ectopic esthesioneuroblastoma developing from the region outside the olfactory epithelium. In addition, tumors occurring in the pterygopalatine fossa (PPF) are uncommon, and the endoscopic transnasal approach for the resection of malignant tumors in this region is also uncommon. CLINICAL PRESENTATION: We describe an esthesioneuroblastoma arising from the left maxillary sinus and PPF. The tumor was resected using the endoscopic transnasal approach, followed by treatment with radiotherapy. The patient showed no evidence of recurrence 12 months postoperatively. TECHNIQUE: The endoscopic transnasal approach could be successfully used for the complete removal of malignant tumors in the PPF. CONCLUSION: The PPF is an anatomic area that is difficult to access. The endoscopic transnasal approach improves access and visualization; it also has the potential to reduce complications compared with the open approach. The endoscopic transnasal approach might become the treatment of choice for malignant tumors in the PPF.

There is nothing quite as devastating as hearing that word - neuroblastoma. In seconds your world is turned upside down and your normal life is but a distant memory. You are thrust into a confusing world full of fear. Your child has cancer.

We know. We have been there. The Neuroblastoma Foundation is here for you.

Welcome to our website. It is a place for you to find answers and ask questions. One of the primary goals of the Neuroblastoma Foundation is to ensure that parents, patients and health care professionals find the information they need to make the best treatment decisions possible for children and adults affected by neuroblastoma. There is a vast amount of information throughout the internet, much of which is encapsulated in medical jargon that is so complex that even many medical professionals have difficulty in interpreting its meaning. We are here to help to decipher this information and to make sure you (and your oncologist) understand exactly what it means to you. From treatment decisions to side effects we have parents and experts that have experienced it all and are willing to distill it for you.
