**Question:** All are true about Nasal Glioma Except

A. Nasal gliomas are rare tumors in pediatric patients.
B. Nasal gliomas are typically benign.
C. Nasal gliomas usually present with unilateral nasal obstruction and epistaxis.
D. Nasal gliomas are highly malignant and have a poor prognosis.

**Correct Answer:** D. Nasal gliomas are highly malignant and have a poor prognosis.

**Core Concept:** Nasal Gliomas are benign, slow-growing tumors originating from the Schwann cells (neuroectodermal cells) of the nasal cavity and paranasal sinuses. They are rare tumors, predominantly affecting pediatric patients.

**Why the Correct Answer is Right:** Nasal gliomas are benign tumors, meaning they exhibit limited growth and slow progression. Although they can cause symptoms like nasal obstruction and epistaxis, they are not highly malignant like option D suggests. Additionally, their prognosis is generally favorable due to their benign nature.

**Why Each Wrong Option is Incorrect:**

A. Nasal gliomas are not highly malignant, making option A incorrect. Although they can cause significant symptoms, their growth rate is generally slow, and prognosis is favorable.

B. Unlike option D, nasal gliomas are not highly malignant, making option B incorrect. They are benign tumors with slow growth and generally favorable prognosis.

C. The other options are correct, indicating that nasal gliomas can cause symptoms like nasal obstruction and epistaxis, which are typical presentation of these tumors.

**Clinical Pearl:** Understanding the nature of nasal gliomas is crucial for accurate diagnosis and treatment planning. Although they can present with symptoms like epistaxis and nasal obstruction, their malignant potential and prognosis differ significantly from highly malignant tumors.
