• Giant naevus
• Artificial dermis
• Tissue expander
• Skin grafting
• Follow-up

We present an ultra-long followed-up case in which an artificial dermis was used for the treatment of a giant naevus. A 5-year-old boy had a giant naevus on his lower back and both buttocks. The light black pigmentation extended to the lower abdomen and both upper thighs. The lesions on the lower back and both buttocks were treated using the artificial dermis Pelnac in three operative series every 2 years. After removal of the lesion, Pelnac was placed onto the skin defect. Three weeks postoperatively, the silicone film was peeled off and a thin split-thickness skin graft (STSG) taken from the upper-middle back was placed on the regenerated dermis-like connective tissue. Thin STSGs were harvested from the same upper back area repeatedly. The lesions on both posteromedial upper thighs and the lower abdomen were treated in three operative series using tissue expanders. Finally, tissue expanders were inserted subcutaneously in both buttocks where Pelnac had been used 5 years or 7 years before. The lesions around the anus were reconstructed using the expanded skin and local skin flaps. Twenty-two years after the first operation, both grafted and donor sites keep good condition not only cosmetically but also functionally.
