D.  Occupational risk

E.  Origin in the maxillary antrum

  5.  A 35-year-old man presents with unilateral nasal obstruction. Inspection reveals an exophytic growth filling the right nasal fossa. The lesion is removed. Its microscopic appearance is shown in this picture. Which of the following is true about this polyp?

C.  Associated with 10% risk of invasive carcinoma

D.  Develops from the lateral nasal wall

E.  Develops in the vestibule

  6.  This photomicrograph shows a papilloma removed from the nasal fossa of a 50-year-old man who presented with epistaxis. Which of the following is true about this lesion?



A.  Develops from the lateral nasal wall.

B.  HPV is found in the majority of cases.

C.  Not associated with risk of invasive carcinoma.

D.  Recurrence rate is 5% with simple excision.

E.  Women are affected more often than men.

  7.  Which type of papilloma is the one shown in this photomicrograph?



A.  Inflammatory

B.  Schneiderian, fungiform type

C.  Schneiderian, inverted type

D.  Schneiderian, oncocytic type

E.  Squamous

  8.  A 58-year-old male with history of chronic rhinosinusitis undergoes resection of a polypoid lesion growing in the posterior nasal septum. The microscopic appearance of the lesion is demonstrated in this low-power photomicrograph. On high power, the epithelium lining the glands resembles respiratory epithelium. Which of the following is the most likely diagnosis?



A.  Chondromesenchymal hamartoma

B.  Inflammatory polyp

C.  Low-grade adenocarcinoma

D.  Respiratory epithelial adenomatoid hamartoma

E.  Schneiderian, fungiform type

A.  Epstein-Barr virus

B.  Human papillomavirus

C.  Second primary in the contralateral antrum

D.  Second primary in the head and neck

E.  Smoking history

10.  A 14-year-old boy undergoes biopsy of a nasopharyngeal lesion near the eustachian tube opening. The microscopic appearance of the lesion is shown in this picture. Which of the following is the most likely diagnosis?



A.  Squamous cell carcinoma, keratinizing

B.  Squamous cell carcinoma, nonkeratinizing

C.  Undifferentiated carcinoma, Regaud pattern

D.  Undifferentiated carcinoma, Schmincke pattern

11.  A midline sinonasal tumor from a 25-year-old woman consists of sheets of poorly cohesive cells with scanty cytoplasm and uniform nuclei with prominent nucleoli, as shown in picture A. Mitotic figures and apoptotic bodies are numerous. Scattered throughout the tumor are foci of abrupt keratinization, as demonstrated in picture B. This tumor is most likely to express:




A.  CD45

B.  CD99

C.  HMB45

D.  NUT protein
