Nine-year-old Jessica Brett faced a rare and potentially life-threatening birthmark that covered nearly half her head. Doctors warned that the large congenital melanocytic nevus carried a risk of becoming cancerous if left untreated.

After careful planning, specialists performed a pioneering procedure never before carried out in the UK. Surgeons placed water-filled (saline) balloons beneath her scalp and gradually inflated them over several months. This innovative tissue-expansion technique stretched the healthy skin, creating enough extra tissue so the birthmark could be safely removed while allowing Jessica to keep her own hair.

Despite the unusual appearance during treatment—when the inflated balloons created temporary “buns” on her head—Jessica remained strong and brave throughout the process. Today, she is recovering well, with new hair growing back over the treated area and a future full of possibilities ahead of her.
