Medical Quiz - Do You Know?

This is a real Quiz and I don't have the answer.

This is a photo I took in Honduras of a woman's foot. It is resting on a wheelchair as she previously underwent a BKA (below the knee) amputation for complications of diabetes. She now had this strange, slightly ulcerated, non tender lesion on her foot for several months. You can see a smaller, less ulcerated lesion on her heel area.

I could not make a diagnosis without a biopsy. It did not appear infected, but certainly it could have been atypical TB. I also thought of necrobiosis lipoidica diabeticorum but it did not have the shiny typical features.

In Roatan there is no dermatologist nor did I have the means to do a biopsy with pathology. My final diagnosis was a pyogenic granuloma. Any ideas from you diagnosticians out there?

It could be - as it looks like a pyogenic granuloma. With the pyogenic granulomas they come on really quickly and get very large, over the course of weeks to months. Every time I see a lesion that looks like that, and the history reveals such a rapid growth that I feel like I have to get the person into a Derm within a week, it is usually a PG - and I relax a bit! What did you do?

You probably already thought of these and ruled them out.
Do you think it could have been from a Brown Recluse Spider bite? Or MRSA?
Thought about Lymes from a tic bite but didn't think it looked like it.

Your differential is sound. I think I agree with pyogenic granuloma too.

What is the treatment for your diagnosis that you gave your patient?

jason: It was Honduras. I gave her a topical antibiotic and told her to return to the clinic if it changed, grew, got red or started hurting.

anon: I ruled out spider bite and MRSA. Thanks.
