Tissue expansion in treatment of facial congenital giant nevus / 中华医学美学美容杂志

Objective To investigate the effect of tissue expansion in facial congenital giant nevus.Methods From October 2014 to October 2016,7 cases of facial congenital giant nevus patients were treated with expanded skin flaps,including single expansion and secondary expansion.Partial excision and skin tissue expansion were used to drastically remove giant pigmented nevi on body or extremities of infants.There were some points for attention during the surgery:the size and location of the partial excision and expander should be designed reasonably;no tumor-manipulation and non-tension principle should be taken great notice,and expanders should be linked up with one another when several expanders were used at the same time,so as to reduce the possibility of forming the envelop,which was favorable for the second surgery of transfer of a skin flap.Results All cases of giant pigmented nevi excision were on the face,which were completely removed from the patients.The areas of the nevi were from 7 cm × 5 cm to 15 cm × 13 cm.All patients were followed up for 3-12 months (mean 6 months).All flaps survived well.Expander exposure was happened in 2 cases with no bad results.One case of scar received late repair due to surgical scars and all got satisfactory results.Conclusions Tissue expansion is an ideal method in the treatment of facial congenital giant nevus.

Nevo sebáceo de Jadassohn gigante / Nevus sebaceous giant Jadassohn

El nevo sebáceo de Jadassohn es un nevo epidérmico compuesto predominantemente por glándulas sebáceas. Clínicamente se presenta como placas redondas u ovales, de color rosado o a veces amarillento, que se localiza en cuero cabelludo, cara, frente, cuello, tronco o extremidades. Estas lesiones pueden alcanzar gran tamaño y provocan en ocasiones una importante deformidad estética. En estos casos poseen alta incidencia de degeneración maligna.Presentamos este caso debido a lo llamativo del tamaño de la lesión...

A Case Report of a Giant Epidermal Nevus on the Scalp

PURPOSE: Epidermal nevi are hamartomas of the skin with multiple clinical variants. Normally, epidermal nevi present at an early age, are found on the head and neck area, and have a female predominance. Only very rarely do epidermal nevi have an adult onset. Most lesions are small and giant Epidermal nevi (> 5 cm at its greatest diameter) are quite rare. Huge verrucous plaque was observed on the scalp of a 70-year-old man. He had been reclusive for a long time, and this problem might have played a crucial role in the development of the giant epidermal nevi. METHODS: A punch biopsy and MRI imaging were performed. The huge mass was resected. A local flap and split thickness skin graft was used for reconstruction. RESULTS: The histology examination revealed the characteristic findings of epidermal nevus. Postoperatively, the patient did not suffer from complications or recurrence. CONCLUSION: A rare case of a huge epidermal nevus on the scalp of an elderly man was treated with a surgical excision. This is the oldest patient reported with an adult onset epidermal nevus in Korea.

Serial Reconstruction Considerating the Aesthetic Unit on Congenital Giant Nevus in Periorbital Area

PURPOSE: Soft tissue deformity and skin defect after tumor resection in the periorbital area can cause trouble in the function of eyelid as well as in the aspect of external appearance. Therefore, as cosidering reconstruction in periorbital area, detailed assessment of both functional and aesthetic property are required. thus, the purpose of this study is to examine an appropriate reconstruction through clinical cases. METHODS: A 14-year-old girl with congenital giant hairy nevus on right periorbital area was selected. Her first visit to our plastic surgery outpatient clinic was on July 2006. Since then, she has undergone staged removal of lesions and reconstruction by various flap technique such as pedicled island flap, forehead galeal flap, paramedian forehead flap, cheek rotation & advancement flap. RESULTS: In the case of this girl, most lesions were removed and replaced by normal skins. Although there was the difference of skin color after skin graft, such difference was not noticeable and section scar by skin flaps was slight. There was no obvious dysfunction in the eyelids and the girl and her parents were satisfied with results after the surgery. CONCLUSION: In the reconstruction of soft tissue defect or soft tissue deformity and contracture, it is required to choose appropriate reconstruction method, considering aesthetic and functional aspects depending on aesthetic unit sufficiently.
