RESUMO
Congenital giant melanocytic nevi of the scalp and forehead are rare lesions present at birth. These lesions are associated with risk of malignant transformation, but they primarily represent a psychological problem to both patient and parents and merit early excision and reconstruction. In this study we report our own experience: seven patients, aged 8 months to 9 years, with congenital pigmented nevi involving forehead and scalp, and a 4-year old patient with congenital pigmented nevus of periorbital region and nose were treated successfully with excision and expanded skin flap reconstructions. The mean expansion procedures were 2 (range, 1 to 3), with an average of 8,8 injections for each expansion procedure (range, 6 to 11). In only one patient simultaneous expanders were placed in the scalp and forehead. Follow-up ranged from 4 months to 15 years. We had no rupture, extrusion or infection of the skin expanders. Complications included eyebrow ptosis and asymmetry in two patients underwent correction at a final procedure. In our opinion tissue expansion is an excellent technique for the treatment of giant nevi of the scalp and forehead because it offers the best aesthetic and functional outcomes.

With the understanding of the extensive vascular supply of the subcutaneous tissue, of its efficacy in the protection of the anatomical structures and of its capability of promoting the adequate functioning of very stressed regions of the human body, the use of subcutaneous adipose flaps has become a valid and sometimes the only reasonable therapeutic weapon in the treatment of small and medium-sized tissue loss. Such a defect represents a common complication of great toe injuries and surgery. Here subcutaneous flap reconstruction is proposed for the treatment of dorsal and medial soft tissue losses of the hallux complicated with infection. Two case are reported. To the best of the authors' knowledge, this application has not been reported in this anatomical site so far. The technique might be worth knowing both for orthopedic and plastic surgeons, as it may represent a safe, less invasive solution for most tegumentary problems of the dorso-medial side of the first ray.
