This was an old cyst. That the blackhead plugs would crumble apart and leak every now and then. With two large blackheads. I always remove the dilated pores so there are no holes left on the back. Only one medical assistant, so sorry no closure on this one. Blackhead removal. Big squeeze. Cyst removal. Dermatology procedure. Dermatology excision. Cyst pop. Juicy plug. MrPopZit.
