This image depicts a very close view of a male patient’s penis, highlighting the right lateral corona of the glans, and its adjacent prepuce, also seen in PHIL 17882. Note the inflamed, swollen lesion, which after a diagnostic work-up, lead to a diagnosis of a primary syphilis, caused by the bacterial spirochete,
. It is important to note that a dark field examination lead to a negative result, even though it turned out that syphilis was, indeed, the cause of this lesion. This is the same patient as was pictured in PHIL 6728, and 6734, depicting a shoulder lesion, which did lead to a positive darkfield examination.
