Its likely a gram negative bacterial infection caused by aeromonas, psuedomonas or similar. Without culturing no one could tell you for sure but statistically, one of fore mentioned infections. Aeromonas are often responsible for "ulcer disease" and often result from a prior parasite infestation.
all I can say is try what has been recommended Eric. Perhaps some one has a better option, but again its what I would be doing.
The parasites create little micro wounds, which get infected...Some would advise to treat with an antibiotic after a parasite infestation to prevent infections.
Yes, in fact flukes/trematodes are the number one cause of ulcer disease.

Here is an excerpt from fishdoc.com
What are ulcers?
An ulcer is defined as a break in the skin extending through all the layers, which fails to heal and is often accompanied by inflammation. The typical skin ulcer has a central area of tissue erosion that may be shallow or deep – in many cases exposing the underlying muscle. Around the edge of the lesion is usually an area of whitish necrotic (dead) tissue and debris, with a large outer zone of inflammation extending into healthy tissue. The scales surrounding the lesion may be raised or infected. Without treatment it gets progressively bigger. In most, but not all, cases they are caused by opportunistic bacteria already in the pond or tank.
How are ulcers caused?
They can be caused by damage to the skin from parasites or chemicals (for example exposure to high levels of ammonia or nitrite or high/low pH) or from trauma caused by breeding efforts or handling. Fish can also be susceptible if their normal defences are compromised by stress. High numbers of opportunistic bacteria, such as would be found in water with a high organic content or other diseased fish, also increase the risk of infection.
If just one is affected it is probably due to a health problem specific to that individual. However if several are affected it is quite likely that there is an underlying environmental problem. In this quite common situation it is no good simply throwing in some anti-bacterial treatment and hoping. It is important to establish and resolve the underlying cause, be it water quality or parasites, as well as treating the bacterial infection.

So Polyguard will take care of this regardless which one it is? I want to get started before the 225g comes in
