Brief Answer: the discharge is likely pus Detailed Answer: Hi, thanks for using healthcare magic A lipoma is a collection of fat cells usually just below the skin. In most cases they do not cause any problem but they can sometimes become inflamed or infected as in your daughter's case. The fatty tissue has a white appearance and the white discharge that you are seeing may be the fatty tissue however in light of the pain and redness, it is more likely a infectious discharge. In the initial stages of infection, the pus may not be fully formed as yet or broken down. The presence of the discharge at this point just indicates that breakdown has occurred. The infection should resolve completely with the antibiotic course. If the lipoma continues to cause future problems she should consider having it removed by a general surgeon. This would be a day case. I hope this helps, feel free to ask any other questions
