Epistaxis

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Olfactory Receptors: Location and Structure

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Olfactory neuroblastoma presenting as bleeding polyp.

Summary

Olfactory neuroblastoma, a rare nasal cavity tumor, was diagnosed in a 13-year-old girl presenting with a nasal polyp. Postoperative radiotherapy was administered due to the absence of intracranial extension.

Area of Science:

Oncology
Otorhinolaryngology
Pathology

Background:

Malignant neoplasms of the nasal cavity are uncommon.
Olfactory neuroblastoma (esthesioneuroblastoma) constitutes a rare subset, representing approximately 6% of sinonasal malignancies.
Fewer than 1,000 cases have been documented globally since its initial description over 75 years ago.

Observation:

A 13-year-old female patient presented with a symptomatic bleeding nasal polyp.
Initial clinical assessment did not reveal overt signs suggestive of malignancy.
Surgical intervention was performed, followed by histopathological examination.

Findings:

Histopathology confirmed the diagnosis of olfactory neuroblastoma.
The tumor exhibited no evidence of intracranial extension.

The patient received adjuvant radiotherapy post-surgery.

Implications:

This case highlights the importance of thorough histopathological evaluation for nasal polyps, even in the absence of apparent malignancy.
Early diagnosis and appropriate management, including radiotherapy for non-metastatic olfactory neuroblastoma, are crucial for favorable outcomes.
Further research into the specific characteristics and treatment nuances of pediatric olfactory neuroblastoma is warranted.
