Hello,
I understand your concern.
I am Dr. Arun Tank, infectious diseases specialist, answering your query.
Epidermoid cyst appears on the germline fusion at the time of birth.
As the site you have mentioned is not the germ line fusion.
So it is not epidermoid cyst it is likely to be other cyst. As doctor described you as
keratin cyst.
Treatment of the keratin cyst is the surgical excision.
If it is infected, we should first treat it with antibiotics there after treatment should be started.
I suggest
cefixime tablet three tines a day under your doctors guidance. Local cleanliness and dressing is very important, this will clear the infection early.
I will be happy to answer your further concern, you can ask me on bit.ly/DrArun.
Thank you.
Dr Arun Tank
Infectious diseases specialist.
