Dear colleagues,

I have the following case to share for your thoughts :

History:

- 50 year old female
- Painless acquired unique lesion of 2 months duration

Investigations:

- FBC, LFT, Renal function normal
- ESR was 50
- No biopsy performed (not available)

What would be your diagnosis or differential diagnosis ?

On the facebook page: out of the 50k photo views and 800+ forum topic visits, here are a few comments (50+) that I found interesting:

-"I think its not spot diagnosis. One can make a list of differential diagnosis. Standard medical approach is then needed to reach to the final diagnosis...
...1. My differential would be cutaneous leishmaniasis , BCC, tuberculosis verruca cutis". And need a biopsy an H/o of disease...

-leishmaniasis was mentioned 27 times
-tuberculosis verruca cutis was mentioned 17 times
