A primary sellar esthesioneuroblastomas with unusual presentations: a case report and reviews of literatures.
The development of an esthesioneuroblastoma outside to the region in which olfactory epithelium exists is extremely rare. Only nine cases were reported in the previous literatures. The author presents a 40 years-old man with ectopic esthesioneuroblastoma in sella turcica. In contrast to the previous nine cases, our case presented unusual presentations-CSF rhinorrhea and meningitis. Endoscopic transphenoid approach with removal of tumor and repair of dura defect followed by radiotherapy offered a good result in this case. Moreover, differential diagnosis and the origin of the ectopic esthsioneuroblastoma would be discussed.
