Which of the following ulcers is classified as painful ?
Show answer Hide answer
Answer: C. oral chancre
Explanation
An oral chancre represents the primary infectious lesion characteristic of early syphilis. It typically presents as a painless ulcerated nodule accompanied by firm regional lymphadenopathy. The absence of pain often delays patients from seeking prompt medical evaluation. Syphilis is a sexually transmitted bacterial infection caused by the spirochete Treponema pallidum. Primary chancres develop at the direct site of spirochete inoculation within the oral cavity. Serological tests are essential for confirming the diagnosis of primary syphilitic infections.
Dental professionals perform intraoral examinations that can detect early painless infectious lesions. Early identification and antibiotic treatment prevent disease progression into secondary and tertiary stages. Understanding ulcer pain characteristics aids in differential diagnosis of various oral mucosal lesions. Syphilitic ulcers in later stages or other oral ulcers typically present with varying pain levels. Trophic ulcers result from neural damage and are frequently painless chronic localized wounds. Listing all options as painful is incorrect because oral chancres are classically painless.
