Esthesioneuroblastoma: A Case Report

Introduction: Esthesioneuroblastoma is an uncommon malignant tumor that arises from the olfactory epithelium and usually involves the anterior cranial fossa and nasal cavity. The main symptoms are unilateral nasal obstruction, epistaxis, and anosmia. The diagnosis is based on an anatomopathologic study. The treatment consists of the combination of surgery and radiotherapy. As endoscopic technique has advanced, this approach has been recommended to avoid morbidity and to reduce costs.

Objective: This study aims to report a case of esthesioneuroblastoma with an endoscopic resection, considering its diagnostic and therapeutic aspects.

Resumed Report: A 36-year-old male patient, farmer, presented with nasal obstruction for 1 year and rhinorrhea and hyposmia for 4 months. The computed tomography showed an expansive lesion in the nasal cavities, maxillary sinus, ethmoid, and invasion of the skull base in the region of the anterior fossa. Patient underwent endonasal surgery with complete excision of the tumor without complications. Intraoperative frozen biopsy during the procedure was performed and the result was consistent with esthesioneuroblastoma. On the 16th day, postoperative patient was asymptomatic and was referred to the oncology service for radiotherapy.

Conclusion: The complete resection of esthesioneuroblastoma with endonasal surgery is possible and avoid esthetic and functional sequelae of transfacial accesses. Another advantage is meticulous excision of the site of tumor implantation. In this case, the action is still new to complete something about the prognosis.
