The Great Imitator Strikes Again: Syphilis Presenting as “Tongue Changing Colors”

Abstract EN

Syphilis is known as the great imitator, making its diagnosis in the emergency department difficult.

A 29-year-old male presented with the chief complaint of “my tongue is changing colors.” A syphilis rapid plasma reagin (RPR) test resulted as positive.

In primary syphilis, the chancre is the characteristic lesion.

While chancres are frequently found on the external genitalia or anus, extragenital chancres arise in 2% of patients.

With oral involvement, the chancre is commonly found on the lip or tongue.

The patient was treated for secondary syphilis with 2.4 million units of long acting penicillin intramuscularly.

On follow-up a month later, the patient’s symptoms had resolved.
