Radical Resection of Facial Giant Congenital Melanocytic Nevus and Reconstruction with Anterolateral Thigh Flap Combined with Tensor Fascia Latae Flap: Case Report

以合併闊筋膜張肌皮瓣及前外股自由皮瓣來重建廣泛性切除臉部巨大先天性黑細胞痣皮膚缺損

摘要


治療巨大先天性黑細胞痣的方法仍在爭議中,最重要原則是惡性腫瘤轉變及外表美觀,當巨大先天性黑細胞痣長在臉部對外觀影響更加重要,外科處理方法包括括除雷射磨皮、切除、植皮、組織擴張器、局部皮瓣及自由皮瓣,因為巨大先天性黑細胞痣在3到5歲會有惡性腫瘤轉變的可能,最好越早期切除越好,雖然在幼兒病人施行自由皮瓣顯微手術較為困難,我們報告一例3歲女性因右臉巨大先天性黑細胞痣接受廣泛性切除並以合併闊筋膜張肌皮瓣及前外股自由皮瓣來重建臉部皮膚缺損,術後追蹤三年,右臉部皮瓣循環良好無任何壞死且臉部痣已完全切除,左腿皮瓣供應區除植皮疤痕外無運動功能限制。

The management of giant congenital melanocytic nevi (GCMN) remains controversial. The significant principle concerns with these lesions are malignant transformation and cosmetic appearance. Facial aesthetics are extremely important when the nevus involves the face. Surgical treatments available include curettage, dermabrasion with Carbon Dioxide laser, serial excision, skin graft, tissue expander, local flaps, regional flaps and microvascular free flaps. Owing to malignant change of GCMN in the first 3 to 5 years of life, it seems best to excise them as early as technically possible. Although microsurgical technique is very difficult especially in pediatric patient, we present a 3 year-old pediatric patient who underwent a salvage reconstruction with combined free Tensor Faciae Latae (TFL) musculocutaneous flap and Anterolateral Thigh (ALT) fasciocutaneous flap for resurfacing of an extensive defect on her right face and neck after radical excision of GCMN.
