Sample itemA young woman complains that her family notices a foul smell from her nose. She herself cannot smell it. Examination shows wide nasal cavities, atrophic turbinates and greenish crusts. What is the most likely diagnosis?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Primary atrophic rhinitis
Primary atrophic rhinitis (ozaena) is characterised by atrophy of the mucosa and turbinates, foul-smelling crusts and anosmia, so the patient is unaware of the smell. Klebsiella ozaenae is often cultured, and treatment includes nasal irrigation and crust removal.
Option by option
A. Primary atrophic rhinitis (correct)
Atrophy with crusting and fetor with the patient unaware of the smell is typical of ozaena.
B. Rhinitis medicamentosa
Rhinitis medicamentosa gives swollen, congested mucosa after overuse of decongestant drops.
C. Allergic rhinitis
Allergic rhinitis gives pale boggy mucosa with sneezing and watery discharge, not atrophy.
D. Nasal diphtheria
Nasal diphtheria causes a membrane and blood-stained discharge, usually in a child.
