|Description:||This patient presented with a shoulder lesion during the primary stage of syphilis, which was diagnosed even after receiving a negative“dark field” examination of the patient's penile lesion pictured in PHIL 17035 and 17882.|
Every genital lesion should be considered syphilitic until proven otherwise. Extragenital lesions characterized by indolence, induration, and regional lymphadenopathy should be regarded as possibly syphilitic. Failure to find the organism does not exclude a diagnosis of syphilis. For additional information regarding the method and interpretation of a dark field examination, see the link below.
