巨型先天性黑素细胞痣(giant congenital melanocytic nevu)简称巨痣(giant nevus),是一种以痣面积巨大为特征的先天性黑素痣,可分布在身体各处.巨痣致患儿外形丑陋,使患儿及其父母产生巨大心理负担.巨痣还有恶变可能,恶变率为4%~12%[1-3],恶变主要取决于痣的病理类型及大小.60%恶变是在第1个10年内,因此小儿巨痣的早期治疗非常必要.治疗目的:防止恶变和改善外貌,减轻患儿自卑心理.巨痣的治疗方法很多,如激光、化学药物、冷冻、外科切除等.手术是可靠的治疗方法,可以完整切除病变,降低恶变率.巨痣面积大,需多次手术,给患儿及家庭带来沉重的经济及心理负担.我们利用小儿头皮面积占体表总面积较成年人高的特点,用大张头皮治疗小儿巨痣. 相似文献

The surgical management of giant congenital melanocytic naevi involving extremities in a circumferential pattern may represent
a surgical challenge with respect to their resection and subsequent reconstructive options. We present our experience in the
management of circumferential giant congenital melanocytic naevi involving the upper limb in one patient and lower limb in
another one. They were managed and followed up for 13 years. The lesion regenerated following dermabrasion in the first patient
and regenerated following tangential excision and split-thickness skin graft in both patients. Therefore, another approach
was used, full-thickness resection of the lesions and reconstruction with dermal regeneration template (Integra™), followed
by ultrathin split-thickness skin graft. The last approach resulted in no recurrence during a 3-year follow-up. The complexity
of these lesions and the limitation of different surgical approaches have been highlighted. Full-thickness excision of the
affected integument and the use of dermal regeneration template is a useful technique which can be considered in the management
of circumferential giant melanocytic naevi, particularly when other established methods have failed to provide satisfactory
results. 相似文献

BACKGROUND: Dermabrasion is one approach to the treatment of treating giant melanocytic congenital nevi. Treatment is recommended to reduce the risk of spontaneous malignant transformation of giant nevi into malignant melanomas that usually occur in childhood. OBJECTIVE: To describe the development of a multicentric malignant melanoma in a giant melanocytic congenital nevus after dermabrasion. METHODS: We report about a 46-year-old male patient who developed a multicentric malignant melanoma in a giant melanocytic congenital nevus. The nevus was located on his left shoulder extending to his neck and chest. Previously, dermabrasion of the nevus was performed twice at the ages of 26 and 28. RESULTS: To our knowledge, this is the first report of malignant transformation of a giant nevus into a multicentric malignant melanoma diagnosed 20 years after the procedure of dermabrasion. CONCLUSION: We conclude that a close follow-up of such patients is mandatory. 相似文献

BACKGROUND: Giant congenital melanocytic nevi represent a surgical challenge, particularly in cases in which the size of the nevus exceeds certain extend and malignant transformations have to be considered. OBJECTIVE: To discuss through case report considerable surgical options when extensive giant congenital melanocytic nevi with malignant transformation are encountered. METHODS: We present an unusual case of a giant congenital melanocytic nevi of the entire back of a 44-year-old patient. To achieve radical resection with direct appropriate wound closure and acceptable outcome, the integument of the entire back was excised and covered with Integra, followed by split-thickness skin grafting after stable integration of the matrix. RESULTS: The approach resulted in a complete excision of the tumor and acceptable cosmetic and excellent biomechanical outcome. CONCLUSION: The introduced practice demonstrates a useful alternative to established methods, particularly if tumor excision in large areas and subsequent wound closure might be achieved in one procedure. 相似文献

目的探讨巨痣的疾病特点,提高对巨痣的临床诊治水平。方法对1例罕见巨痣病例进行报道,并结合文献报道的资料进行分析总结。结果本例患者19岁,自出生即被发现项背部巨痣,在我院行病变组织切除植皮术,术中发现痣细胞侵及脂肪和肌肉层。随访7年,高度怀疑并发神经皮肤黑变病。结论结合本病例及文献分析,整形外科医师应认识到巨痣的痣细胞可能侵犯较深(甚至达脂肪、肌肉层),且可能并发神经皮肤黑变病。因此,手术前应全面系统考虑患者的病史、可能的并发症及首选的治疗手段,必要时应与皮肤科及神经科多学科合作共同完成治疗,以防延误病情,减少并发症发生的风险。 相似文献

Nevus comedonicus is a rare developmental abnormality of the pilosebaceous apparatus that presents as an aggregation of dilated follicular orifices filled with pigmented keratinous material. Occurrence of extensive or giant lesions is even more rare. Indications for treatment include recurrent infections and cosmetic reasons. Therapeutic approaches include topical keratolytic agents, manual extraction of comedones, dermabrasion, and excision of smaller lesions. Increasing clinical experience with tissue expansion has suggested that it might be used effectively in the definitive treatment of an extensive nevus comedonicus previously considered too large to excise without the use of a skin graft, despite the potential risk of infection within the lesion during the course of expansion. We report the first patient with giant nevus comedonicus to be treated using tissue expansion. This patient demonstrates that prompt treatment of cellulitis and abscesses within the lesion will keep this process isolated from the adjacent expanders and will not compromise a planned excision and reconstruction. 相似文献

BACKGROUND: Congenital Spitz nevus has been reported previously in the literature, but the histopathologic features have not been examined in detail. OBJECTIVE: To histologically examine and report on congenital Spitz nevus. METHOD: We examined 10 clinically submitted congenital melanocytic nevi that were histopathologically identified as congenital Spitz nevi and compared them to the characteristics seen in acquired Spitz nevus and superficial congenital melanocytic nevus. RESULTS: Of the 10 congenital Spitz nevi, 9 were compound and 1 was dermal. Two showed features of combined Spitz nevus (Spitz and blue). Six cases showed all 16 listed characteristics of acquired Spitz nevus, with two cases having 15 and two cases having 14 characteristics. Of the superficial congenital melanocytic nevus characteristics, all except three cases had all 12 attributes. The one dermal lesion had all the characteristics of the acquired Spitz nevus and all but one of the characteristics of the superficial congenital melanocytic nevus in regards to intradermal findings. CONCLUSIONS: Congenital Spitz nevi are true congenital lesions, with histopathologic features of both acquired Spitz nevus and superficial congenital melanocytic nevus. 相似文献

The presence of deep pigmentation in a giant congenital nevus makes its complete removal very difficult and should be taken into consideration when planning for treatment. A clinical case in which the pigmented lesion was found to extend deep into the muscle fascia is described. The lesion was surgically removed with an acceptable functional and aesthetic result through the utilization of tissue expansion. The development of new surgical techniques and the expansion of laser technology will possibly provide new treatment options in the future. Emphasis should be placed on aesthetics and function, because the excision based only on oncological anticipation is no longer valid. The presence of deep pigmentation makes certain treatment options less effective than surgical ablation. 相似文献

Surgical excision of giant congenital nevi is recommended by principle for dermatological reasons. Malignant potential is real but its incidence remains widely discussed. Their excision represents a surgical challenge but is also a real assault course for the child and his family. The sequelae and the psychological effects can be important. Can an incomplete excision to limit these aesthetic after-effects and relieve the surgical treatment be acceptable? We present the case of a child affected by a giant congenital nevi of the cephalic extremity where the excision was partial. A review of the literature on the degenerative risk of the giant congenital nevi allowed us of noticed that this one tends to be overestimated. The advantages and the disadvantages to practise a preventive, premature excision and complete of the giant congenital nevi are approached. We discuss the possibility to resort to a partial excision in certain cases delicate of reconstruction under the cover of a strict and moved closer dermatological surveillance. 相似文献
