Sentinel Pile? Genital Wart? Skin Tag?

A few months ago, I noticed one small bump on the skin in between the anus and vaginal opening.  I went to the doctor, who said it was a wart (HPV) or a skin tag.  

For a period of time before that I had been dealing with an anal fissure.  It was only later that I realized the two might be connected.   I've read about sentinel tags/piles, but am not sure if this could be the cause of the bump. The bump seemed to stop growing as the anal fissure was treated.  But this might be a coincidence . . .

Can sentinel piles occur on the skin between the anus and vagina?  Can a sentinel tag be close enough to the vagina to be mistaken for a genital wart?
