Dentistry · Oral medicine and oral cancer: tertiary syphilis of the palate
Sample itemA man who never received treatment for an infection acquired years ago has a painless, necrotic destructive lesion in the midline of the hard palate that has perforated into the nasal cavity. He has a nasal voice. What is the lesion?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Gumma
A gumma is a granulomatous destructive lesion of tertiary syphilis; in the mouth it favours the hard palate, where it can perforate into the nose. Primary and secondary lesions appear much earlier.
Option by option
A. Chancre
A chancre is the painless primary ulcer at the inoculation site within weeks.
B. Mucous patch
Mucous patches are shallow grey erosions of secondary syphilis and do not perforate.
C. Condyloma lata
Condyloma lata are moist papules of secondary syphilis.
D. Gumma (correct)
Correct. A late destructive palatal lesion with perforation is a syphilitic gumma.
