Dissecting cellulitis can cause painful scalp bumps, drainage, tunnels, scarring, and recurrence. Our study found PIILIF, a hidden inflammatory pattern, in active bumps, quiet bumps, and even normal-looking scalp. That may help explain relapse. The visible bump may only be part of the disease. What surprised you most about where PIILIF was found? Yes/No: Can normal-looking scalp still be part of the inflammatory picture?
