1/9. Multicentric malignant melanoma in a giant melanocytic congenital nevus 20 years after dermabrasion in adulthood.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.- - - - - - - - - - ranking = 1keywords = dermabrasion (Clic here for more details about this article) |
2/9. Treatment of nevus comedonicus with topical tazarotene and calcipotriene.nevus comedonicus is a rare developmental defect of the pilosebaceous unit. It is also thought to be a variant of epidermal nevus. Previously reported treatments include surgical excision, CO2 laser, dermabrasion, extraction, topical retinoic acid, and numerous topical keratolytics. We present a case of a 7-year-old boy with bilateral nevus comedonicus who experienced cosmetic improvement with topical tazarotene and calcipotriene cream. This combination represents a novel therapeutic approach to the treatment of this cutaneous abnormality.- - - - - - - - - - ranking = 0.14285714285714keywords = dermabrasion (Clic here for more details about this article) |
3/9. Giant congenital melanocytic naevus in association with hepatic melanin deposits.This report describes a neonate with a giant congenital pigmented naevus over most of the trunk surface area, along with multiple satellite lesions, especially over the legs. magnetic resonance imaging of the abdomen showed large deposits of melanin in the glutei bilaterally, the rectus abdominis muscles and the liver. Treatment consisted of repeated dermabrasion of the naevus over the lower back with CO2 laser (silk touch), followed by autologous skin grafting. No evidence of malignant transformation was observed. Conclusion: Giant congenital melanocytic naevus may be associated with involvement of internal organs other than the central nervous system.- - - - - - - - - - ranking = 0.14285714285714keywords = dermabrasion (Clic here for more details about this article) |
4/9. Giant congenital melanocytic nevi of the trunk and an algorithm for treatment.Giant congenital melanocytic nevi (CMN) are rare, congenital, disfiguring lesions with a risk of degeneration to malignant melanoma. Giant CMN are associated with an increased risk of malignant degeneration. In a minority of cases, patients with giant CMN may have associated neurocutaneous melanosis with leptomeningeal involvement. Giant CMN of the trunk pose difficult diagnostic and reconstructive problems requiring complex multistage treatment. For high-risk cases, diagnostic evaluation in the form of neuro-imaging is an essential component of the planning phase. Although nonsurgical options for the treatment of giant CMN have been advocated, these modalities may decrease the burden of nevus cells but do not result in complete removal of these cells. The ability to monitor nevus cells that remain after nonsurgical management of giant CMN remains questionable. These nonsurgical options include dermabrasion, laser ablation, and chemical peel. In contrast, direct excision of the nevus is the mainstay of treatment of nonsurgical management of giant CMN. There are numerous surgical options to resurface the resultant cutaneous defect after excision of the nevus. The simplest of these options consists of serial excision and direct closure of the defect in stages. However, if the defect cannot be closed by direct cutaneous advancement, other options for wound resurfacing include split- or full-thickness skin graft, tissue expansion, and free tissue transfer. tissue expansion should be viewed as a category of treatment options because expanders can be used to create an expanded full-thickness skin graft, local expanded flaps adjacent to the lesion, or expansion of a free tissue donor site. Given the diversity of reconstructive options that use tissue expansion, these techniques have evolved as the primary treatment method for giant CMN of the trunk. The authors outline an approach to the evaluation of giant CMN of the trunk, review the risks of melanoma and of neurocutaneous melanosis, describe their preferred treatment regimen, and offer a treatment algorithm for giant CMN of the trunk.- - - - - - - - - - ranking = 0.14285714285714keywords = dermabrasion (Clic here for more details about this article) |
5/9. comparative study of dermabrasion, phenol peel, and acetic acid peel.Six areas of the face and forehead of a 36-year-old white female presenting with a benign congenital blue nevus of the skin were treated by dermabrasion, bichloracetic acid, and the classic phenol peel. Comparative results at six months showed each of these methods to be approximately equal in the depth of penetration and in the quality of skin on healing. However, in these small test sites, dermabrasion appeared to remove pigment slightly more efficiently. Therefore, her forehead and cheeks were treated with dermabrasion and subsequently with chemical peel. An attempt was made to touch up the dermabraded areas with acetic acid. Full thickness burns occurred, which resulted in thick scarring that required many months to finally heal. We conclude that at least in the treatment of pigmented lesions, the modalities of phenol, acetic acid, and dermabrasion are approximately equal.- - - - - - - - - - ranking = 1.1428571428571keywords = dermabrasion (Clic here for more details about this article) |
6/9. A combined case of desmoplastic trichoepithelioma and nevus cell nevus.A 41-year-old woman with desmoplastic trichoepithelioma associated with pigmented nevus presented. Pigmented nevus had been present on her face at birth. She had received cryotherapy and dermabrasion at a small part of the pigmented nevus. As a result of the therapy, the discoloration disappeared. The lesion lately increased and became hard. Histologically, the lesion was composed of two distinctive but intimately mixed cellular components; nevus cells and basaloid cells. In the pigmented lesion, basaloid cells were not present. To our knowledge, this is the first reported case of desmoplastic trichoepithelioma associated with nevocellular nevus in japan.- - - - - - - - - - ranking = 0.14285714285714keywords = dermabrasion (Clic here for more details about this article) |
7/9. Pseudomelanoma following laser therapy for congenital nevus.Benign nevi can be removed by a variety of procedures including surgical excision, electrocautery, slicing off the protruding portion by a shave biopsy, cryotherapy, dermabrasion, etc. Except in the case of complete excision, these procedures may often be followed by recurrence. We describe a congenital nevus that was incompletely removed by CO2 laser therapy. When the lesion recurred, it had clinical as well as histologic features in common with malignant melanoma, although it was completely benign.- - - - - - - - - - ranking = 0.14285714285714keywords = dermabrasion (Clic here for more details about this article) |
8/9. The treatment of giant hairy naevi by dermabrasion in the first few weeks of life. case reports.A method for treating congenital giant naevi in the first few weeks of life by mechanical dermabrasion is described. From reports in the literature and from our 2 cases it would seem that this is a very effective method for removing pigmentation early in life. The cosmetic deformity of these lesions is eradicated and their malignant potential possibly minimized.- - - - - - - - - - ranking = 0.71428571428571keywords = dermabrasion (Clic here for more details about this article) |
9/9. Lower and upper extremity atrophy associated with a giant congenital melanocytic nevus.Giant congenital melanocytic nevi (GCMN) may be associated with a variety of malformations. Recently, atrophy of the underlying extremity was reported for the first time. We observed two patients with GCMN on the extremities with marked atrophy of the underlying tissue without functional impairment. According to the definition of hamartoma, it seems possible that one component of tissue has decreased. Dermatologists treating patients with such nevi in the first weeks of life with dermabrasion, laser, or curettage need to know that the natural course of GCMN may lead to atrophy and that this does not necessarily result from the treatment regimen.- - - - - - - - - - ranking = 0.14285714285714keywords = dermabrasion (Clic here for more details about this article) |
