So the clinical features of chancroid include genital ulcers.
Now these in contrast to syphilis - the chancres of syphilis - these are painful.
They are well circumscribed.
whereas the chancres of syphilis are indurated.
They have a rounded, rather firm edge in syphilis.
And these are what we refer to as kind of dirty ulcers.
Their ulcer base is covered with necrotic material,
whereas the lesions of syphilis are cleaner in appearance.
The lesions of chancroid also bleed easily,
and there doesn’t seem to be much inflammation surrounding.
Inguinal lymphadenopathy is present in about 50 percent of individuals,
and sometimes the lymph nodes that are involved are actually fluctuant,
which means that when you press on them, there seems to be fluid in them.
Occasionally, these fluctuant lymph nodes will rupture pus out on to the surface.
Occasionally, it will present in an atypical fashion with multiple coalescent
or even giant ulcers,
or lymphadenitis without an active ulcer.
In other words, the patient has no recollection of any skin lesions on the penis,
or multiple small ulcers that resemble more folliculitis
than a sexually transmitted infection.
And there are non-sexually transmitted cases of chancroid,
and these usually appear in the form of chronic skin ulcers
that are typically on the legs.
I haven’t personally seen these,
but they are reportedly frequent in children
in the Solomon Islands and Papua New Guinea.
