Hi,

I am 30 years of age. I developed this irritating little growth on my skin. Yes, I did what I shouldn't have done and I picked at it. I went to a dermatologist who biopsied it.

The growth is benign. Keratosis. But then the pathologist also found impetigo.

I am not concerned about the benign growth, now I am concerned about the impetigo, I assume, secondary to scratching the growth.

1. How can a biopsy show impetigo on a tissue?
2. Can the pathologist confirm what kind of bacteria is causing the impetigo?

My concern is I have MRSA Impetigo. Is that possible? Would the pathologist be able to rule that out while looking at the specimen if he can already see the impetigo under the microscope?

Thanks.
