ENT · Nose and nasopharynx
Sample itemA 14-year-old boy has progressive nasal obstruction and repeated profuse episodes of unilateral epistaxis. A smooth reddish mass is seen in the nasopharynx. Which is the most likely diagnosis?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Juvenile nasopharyngeal angiofibroma
Juvenile nasopharyngeal angiofibroma is a highly vascular benign tumour almost exclusively of adolescent males, arising near the sphenopalatine foramen. Contrast CT or MRI confirms it, and biopsy is avoided because of the risk of torrential haemorrhage.
Option by option
A. Antrochoanal polyp
An antrochoanal polyp is pale, causes obstruction without recurrent heavy bleeding and is not a vascular tumour.
B. Nasopharyngeal carcinoma
Nasopharyngeal carcinoma occurs mainly in adults and presents with neck nodes and ear symptoms.
C. Juvenile nasopharyngeal angiofibroma (correct)
Adolescent male, nasal obstruction and recurrent profuse epistaxis from a vascular nasopharyngeal mass are typical.
D. Adenoid hypertrophy
Adenoid hypertrophy causes obstruction and mouth breathing but does not cause profuse unilateral epistaxis.
