Specific applications: Radiofrequency commonality
Bipin Deshpande in Dermatologic Surgery with Radiofrequency, 2018
Radiofrequency (RF) surgery is well known for certain applications because of the ease of treatment and the superiority of the results. This chapter covers the most common of indications for which RF surgery is used and is famous for or is always referred to for. These indications are the bread and butter of a RF office surgery. Everyone who desires to use RF surgery in dermatologic surgery or those who have decided to start dermatologic surgery in an office using RF surgery must be thoroughly acquainted with the minutest details of these indications for the best results. The most impressive result of RF surgery is the excision of moles or intradermal nevi, also called melanocytic nevi. However, warts or verrucae are among the most common of all conditions to be treated because of the higher incidence and potential for infection and recurrence. Warts, or verrucae, are some of the most common indications for RF surgery.
Nevi

Melanocytic nevi are benign melanocytic tumors characterized by a very high incidence in the population, especially in Caucasians. Several classifications of nevi have been proposed according to the time of appearance, the histopathologic distribution, or the origin of the stem melanocyte. The dermatoscopic pattern of nevi depends on several factors, including the histopathologic type, the morphological characteristics of the melanocytes and the anatomical site. Four predominant dermatoscopic nevus patterns exist: reticular, globular, starburst, and homogeneous or diffuse. The benign nature of nevi is usually reflected also morphologically, meaning that most nevi are clinically and dermatoscopically symmetric. The dermatoscopic colors and structures are combined in an organized way, which results in a morphological order. The reticular pattern consists of intersecting brown lines that form a pigment network. Histopathologically, the reticular pattern corresponds to the presence of continuous pigmentation along the dermo-epidermal junction, combined with a normal papillomatosis.
Basal Cell and Squamous Cell Carcinomas
Dongyou Liu in Tumors and Cancers, 2017
Tumors affecting the skin include the following categories: keratinocytic tumors, melanocytic tumors, appendageal tumors, hematolymphoid tumors, soft tissue tumors, neural tumors, and inherited tumor syndromes. Within the keratinocytic tumor category, six types of neoplasms or lesions are recognized. They are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), Bowen disease, actinic keratosis, verrucas, and acanthomas. Together with a number of less common skin cancers of nonmelanocyte origin, BCC and SCC are collectively referred to as nonmelanoma skin cancer (NMSC). Differential diagnoses for BCC include actinic keratosis, Bowen disease, fibrous papule of the face, juvenile nasopharyngeal angiofibroma, malignant melanoma, melanocytic nevi, molluscum contagiosum, psoriasis, sebaceous hyperplasia, SCC, and trichoepithelioma. The treatment for BCC and SCC usually involves surgical removal of the lesion. For SCC, surgical excision with adequate margins, curettage, electrodessication, cryotherapy, radiotherapy (external beam radiotherapy or brachytherapy), and chemotherapy may be used. BCC generally has an excellent prognosis.
Congenital melanocytic nevus on the lower eyelid treated with continuous wave and superpulsed CO

There are several therapeutic options to treat congenital melanocytic nevi. The motivations for the treatment of small- to medium-sized congenital nevi located on the face or other sensitive areas are frequently cosmetic. The choice of therapy depends on the operator’s expertise and on the likelihood of improved cosmesis. We report a case of a medium-sized congenital nevi located on the lower eyelid, successfully treated with a combination of ablative lasers with a single surgical procedure. We achieved an excellent clinical and cosmetic result. No scarring, distortion, or recurrence were observed.

Congenital melanocytic nevi (CMN) are benign nevomelanocytic proliferations that are present at birth. CMN are commonly classified according to their size and the management of CMN is diverse, including excision, dermabrasion and laser treatment. Several studies have shown the effectiveness of laser therapy for CMN in cosmetically sensitive and anatomically critical areas. In the present case, combination treatment with intense pulsed light (IPL) and erbium:yttrium-aluminum-garnet (Er:YAG) laser was used, and its effectiveness was evaluated. A 56-year-old man with a CMN on the left malar area was treated with combined IPL and Er:YAG laser treatment once monthly. After ten sessions of treatment, the lesion showed improvement leaving only a grayish hue. Thus, we report a case of CMN on face that was successfully treated with combined IPL and Er:YAG laser treatment.
Successful treatment of congenital melanocytic nevus on tragus with CO
Published in Journal of Dermatological Treatment, 2014
Background: Congenital melanocytic nevus (CMN) has an increasing risk of malignancy and may cause cosmetic and psychological problems. Surgery has been the main therapy for most cases. However, it is often not suitable for all lesions. Treatment of these lesions can be challenging to plastic surgeons. CO2 laser, with the special function, is another effective treatment for some CMN. Methods: Both lesions were treated with a short-pulsed CO2 laser in conjunction with a local anesthetic; the superfluous tissue was pruned and ablated to get a crude tragus and then carefully shaped to form an aesthetically tragus. Results: Showed good cosmetic results without pigment recurrence and scar formation 1 year after operation in both patients, the exception being a small area of cartilage that was covered with epithelial tissues on the surface in patient 1. Conclusions: CO2 laser treatment is a useful modality in treating some CMN that are located on sites deemed inoperable. It can help to shape the lesions into their original form with the advantage of hemostasis and tissue manipulation proving to be effective, thus avoiding suturing and skin grafting. Taking the thermal damage into account can help to minimize the side effects and attain a desirable cosmetic outcome.
