MCQ MAHE 2000 ENT Answer 02

The Correct Answer is D

Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign, vascular neoplasm that accounts for less than 0.5% of all head and neck tumors. JNAs occur almost exclusively in the nasopharynx of adolescent males.

Histologically, JNAs originate from myofibroblasts. The tumor lacks a capsule and spreads submucosally. It is composed of a fibrous abundance of single endothelial cell lined vascular spaces or channels. These channels are surrounded by a collagenous tissue network and lack a complete muscular layer.

JNAs classically presents with unilateral nasal obstruction, epistaxis, and nasopharyngeal mass in adolescent males with an average age of onset of 15 years of age. Conductive hearing loss, dacrocystits, rhinolalia, hard and soft palate deformity, and hyposmia or anosmia are not uncommon presentations. Advanced lesions may cause facial swelling, proptosis, cranial neuropathy, and massive hemorrhage. On physical examination, a smooth lobulated mass is often noted in the nasopharynx and/or lateral nasal wall. They have been described as pale, purplish, red-gray, and beefy red. JNAs are compressible. A patient presenting with the above described signs and symptoms should not undergo biopsy due to the risk of bleeding.
