A congenital nevi is a pigmented patch which requires complete surgical excision for cosmetic reasons. Here, we report a case of a patient with facial hairy pigmented lesion, occupying the right half of her face since birth, who underwent complete surgical excision and staged reconstruction utilizing, preexpanded forehead and neck skin. We used two...

... Although an expanded cervicofacial flap could be advanced from the mandibular region upward and medially, it is difficult to reach the medial canthus in one stage [18]. In this scenario, serial expansion may be helpful. ...
Giant congenital nevi, especially on the head and neck, pose a challenge for plastic surgeons. This requires extensive experience in detailed planning, combining different techniques, and selecting appropriate materials for reconstruction. There have been reports of using a tissue expander, serial resection method, and full-thickness skin grafts for this type of nevus. However, the best way availabl to completely remove a giant congenital nevus is endless. In this article, we would like to present a case of a left hemifacial giant congenital nevus in which we used multiple tissue expansion to fully replace the nevus along with some of our modification techniques.
... e total surface area gain provided by a rectangular-shaped tissue expander is about 40%, which is the highest that can be provided by expanders of any shape. [11] ey could easily resurface the resultant scalp defect following complete excision of lesion. ...
Congenital melanocytic nevi are benign proliferations of cutaneous nevomelanocytes. Usually, they manifest at birth or become apparent within the first few years of life. The nevi show variable surface morphology (papular, rugose, verrucous, or cerebriform). Congenital melanocytic nevus showing cerebriform morphology is a rarity. Early diagnosis and surgical excision are usually recommended in congenital melanocytic nevus to prevent the future risk of malignant transformation which is higher in larger lesions, especially in giant forms (>20 cm in size). An excision of the lesion also helps to avoid the social and psychological consequences arising out of significant cosmetic deformity. We report a 21-year-old patient who presented with a cerebriform congenital melanocytic nevus measuring 10 cm × 7 cm × 2 cm in the right parietal region. Early-onset, pigmented lesion with a cerebriform surface, and the histopathology features of congenital melanocytic nevus were the points that favored the diagnosis of cerebriform congenital melanocytic nevus in our patient. He was treated with excision of the lesion and defect coverage with tissue expansion in two stages. Two rectangular tissue expanders were placed beneath the galea aponeurotica (one with a capacity of 300 cc in the left parietal region and another with 500 cc in the occipital region). Both the expanders were inflated twice to their capacity. Second stage surgery was performed after about 3 months in which the tissue expanders were removed and the pre-expanded scalp skin was used to drape the scalp defect that resulted from the excision of the lesion. An excision and a two staged reconstruction of the scalp using tissue expanders, may ensure a good aesthetic outcome in the management of intermediate to large sized congenital melanocytic nevus.
A girl in her middle childhood presented to the outpatient department (OPD) with a congenital melanocytic naevi (CMN) of the right nasal alar lobule. Her parents had aesthetic concerns and expressed their desire to get the lesion removed. The full-thickness excision of CMN was performed with the reconstruction of the defect using the nasolabial and dorsal nasal advancement flap with conchal cartilage to shape the contour of the ala.
Objective:
Treating large/giant congenital melanocytic nevus (L/GCMN) is challenging for surgeons. Operative approaches commonly used to remove L/GCMN include serial excision, tissue expansion, and skin grafting. Thus, we retrospectively compared these three operations' applications and therapeutic effects.
Methods:
The clinical data of 97 L/GCMN patients from June 1, 2015, to June 1, 2019, were collected and divided into three groups according to the operations used: serial excision group(SE group, n=18), tissue expansion group(TE group, n=23) and skin grafting group(SG group, n=56). The location and size of the lesion, the number of operations, duration of each operation, preoperative preparation time, postoperative hospital stay, complications, and clinical outcomes of all patients were collected and assessed.
Results:
The SE group had the most times of operation (3.9 and 6.0 for LCMN and GCMN, respectively), the shortest surgery length (56.3min), and the shortest postoperative hospital stay (10.0d). The SE and SG groups required much less time to prepare for surgery and had a lower rate of complications than the TE group. During the 11.9-month median follow-up period, the SE and TE groups had better postoperative outcomes than the SG group.
Conclusion:
Each of the three operations has different advantages and disadvantages, and the specific surgical strategy should be decided based on the patient's unique circumstances.
