What if a lipoma is punctured? Should I be concerned?

I had a cyst that formed in the same area as a lipoma. (Just under my jawline on the left side. Approximately a centimeter below the pulse point.The lipoma was identified through an ultrasound in 2001.) The cyst was lanced and drained at Urgent Care, and I've been prescribed a round of antibiotics. Since that occurred it seems as though the lipoma is significantly smaller. I plan on seeing a dermatologist. But I'm a little bit concerned.
