Possibility of pyogenic granuloma
Hello and welcome to healthcaremagic.
I am Dr. kakkar. I have gone through your concern and I have understood it.
I would keep a possibility of pyogenic granuloma, which is a vascular lesion appears as an overgrowth of tissue due to irritation, physical trauma or hormonal
factors etc. Size ranges from a few millimeters to centimeters.
They bleed on the slightest trauma or manipulation. Treatment is with simple cauterization
Since the very reason of pyogenic granuloma in your case could be the physical trauma of scratching, therefore avoiding it to scratch for a few days may be just about enough to cure it. You can use a topical antibiotic
cream e.g 2% mupirocin
can be used twice daily locally over the lesion.
If it still does nt resolve you could go in for cauterization.
