Exclusively endoscopic surgical resection of esthesioneuroblastoma: A systematic review.

World J Otorhinolaryngol Head Neck Surg 2022 Mar 22;8(1):66-72. Epub 2022 Mar 22.

Department of Otolaryngology-Head and Neck Surgery New York-Presbyterian Hospital-Columbia University Irving Medical Center New York New York USA.

Nasoethmoidal Schwannoma as a Mimicar of Esthesioneuroblastoma: A Case Report and Literature Review.

Neurol India 2022 Mar-Apr;70(2):784-787

Department of Otorhinolaryngology, Guru Gobind Singh Medical College and Hospital, Faridkot, Punjab, India.

Nasoethmoidal schwannomas are rare lesions and their presentation with intracranial extension is even rarer. Here, a patient presenting with rhinorrhea, epistaxis, and proptosis of left eye was diagnosed with giant nasoethmoidal schwannoma extending to frontal lobe and orbit, which was managed with bifrontal craniotomy with endoscopic transnasal gross total excision. This being predominantly a benign lesion has good prognosis if total excision is achieved. Read More

Prognostic value of microvessel density and its correlation with clinicopathological features in human olfactory neuroblastoma.

Clin Neuropathol 2022 May-Jun;41(3):114-121

Although angiogenesis plays an important role in tumor growth and invasion, its role in the progression of olfactory neuroblastoma (ONB) has rarely been published. The aim of the present research was to analyze the prognostic role of microvessel density (MVD) in ONB and its association with clinicopathological parameters. 70 ONB cases were assessed for immunohistochemical expression of CD31, CD34, CD105, VEGF, and VEGFR2.

Department of Neurosurgery, Haukeland University Hospital, Bergen, Norway. Electronic address:

This chapter examines the results of GKNS on a variety of extraparenchymal skull base tumors some benign and some malignant. For the benign tumors there is good evidence on the effectiveness of the method for pretty much all diagnoses. For malignant extraparenchymal tumors the results are more limited and GKNS only has a supportive role in these lesions. Read More
