1/19. Lentiginosis profusa. III: Aesthetic and sanguineous aspects.Lentiginosis profusa syndrome and progressive cardiomyopathic lentiginosis are preferable terms to "leopard syndrome". Considerable cosmetic improvement followed facial dermabrasion and light electrodesiccation of lentigines on the exposed surfaces. Hematologic evaluation did not reveal hematopoietic defect in the patient studied.- - - - - - - - - - ranking = 1keywords = dermabrasion (Clic here for more details about this article) |
2/19. "Pot-lid" technique for aesthetic removal of small lipoma on the face.BACKGROUND: patients presenting with an asymptomatic subcutaneous facial lipoma desire its removal in order to restore the contour of the face. The standard treatment for lipoma is excision, with the size of the incision being about one-half of that of the tumor itself. The long linear scar resulting from simple excision may fail to improve the appearance of the patient. The removal of the lipoma through a small incision or a punch hole decreases the size of the resulting scar, but does not eliminate it completely. OBJECTIVE: To improve the aesthetic outcome of the commonly used technique for lipoma removal, known as the narrow hole extrusion technique (NHET), by modification. methods: Four patients (three men and one woman) with small lipomas on the face (three on the forehead and one on the cheek) were selected for the procedure. A 5-mm punch was inserted deep into the center of the lesion to create a circular hole. The punched-out piece of skin was kept in normal saline. The lipoma was extruded with the help of a hemostat and by squeezing pressure. This resulted in the formation of a subcutaneous cavity. After achieving hemostasis, two absorbable buried subcutaneous sutures were placed to create support for the graft. The punched-out piece of skin was then positioned to cover the defect, like a "lid on a pot" and dressed. RESULTS: The color and texture match of the graft with the surrounding skin were excellent in three of the four patients by the end of 6 months. The graft, which was depressed in the fourth patient, improved through spot dermabrasion. CONCLUSION: The proposed modification of the NHET for lipoma removal improves the cosmetic outcome.- - - - - - - - - - ranking = 1keywords = dermabrasion (Clic here for more details about this article) |
3/19. 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 = 7keywords = dermabrasion (Clic here for more details about this article) |
4/19. carbon dioxide laser surgery for skin disease.Since it was developed in the 1960s, the carbon dioxide (CO2) laser has had an important role in the practice of dermatology. The CO2 laser has some advantages over conventional techniques used in dermatologic surgical treatment. It routinely provides a bloodless surgical field as well as unusual surgical precision. Although the CO2 laser is specifically indicated for certain conditions, in other situations, only marginal benefit may be noted in comparison with standard techniques such as scalpel surgical procedures, dermabrasion, cryosurgery, and electrosurgery. In this article, we briefly review the history and physics of the CO2 laser, its operation, and safety principles and discuss dermatologic conditions that are treated with the CO2 laser. We also describe 8 representative cases from our experience with more than 800 cases of CO2 laser treatment in the practice of dermatology at the Mayo Clinic since 1986.- - - - - - - - - - ranking = 1keywords = dermabrasion (Clic here for more details about this article) |
5/19. 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 = 1keywords = dermabrasion (Clic here for more details about this article) |
6/19. 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 = 1keywords = dermabrasion (Clic here for more details about this article) |
7/19. Dermal cylindroma (turban tumor). Case report.We present an unusual case of massive dermal cylindroma (turban tumor), occupying the entire scalpand forehead. It was treated by a total scalping procedure and skin grafting in two stages. Additional tumors of the face, neck, chest, shoulders, and back were excised and closed. The nose was treated by shoving and dermabrasion, similar to a rhinophyma. The lip was treated by dermabrasion. There has been no evidence of recurrence in the scalp which was treated by excision and grafting. There is now a papular quality of the skin over the nose and on the uppler lip, indicating that regrowth may occur. The etiology, pathology, and a review of the literature are presented.- - - - - - - - - - ranking = 2keywords = dermabrasion (Clic here for more details about this article) |
8/19. 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 = 1keywords = dermabrasion (Clic here for more details about this article) |
9/19. Giant congenital nevus and malignant melanoma.Frequency of malignant transformation arising in giant congenital nevi is considered to be 4%-5%. More than a half of the patients in which malignant melanoma developed in giant congenital nevi were under the age of 10. It may be hypothesized that dermabrasion of giant congenital nevus may provoke malignant transformation. Some of the cell groups in giant congenital nevus are potentially malignant. Some groups of nevus cells were larger in size than those of other portions of nevus. Electron microscopic observation revealed that nuclei of these larger nevus cells were significantly indented, and melanization of melanosomes was irregular. Coexistence of alpha-like actin with beta- and gamma-actins in giant congenital nevus cells and disappearance of alpha-like actin in malignant melanoma cells were noted.- - - - - - - - - - ranking = 1keywords = dermabrasion (Clic here for more details about this article) |
10/19. 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 = 1keywords = dermabrasion (Clic here for more details about this article) |
