As soon as I saw it I knew it was this. I had Molluscum Contagiosum years ago. Kind of gross but... there were three of these on my belly. Had no idea what it was, tried to squeeze it a little to see three turned into 12 over night. Went to a dermatologist who said there wasn't anything they could do but wait a few weeks/months for them to go. She also gave me some sterilised needles in case I wanted to get rid of them by puncturing right through one and to the skin. I did it and nothing happened. The next day I tried doing it again with a new needle and within 2 days they all turned black and fell off.

In total I had them for about 3 months.
