Introduction: Surgical methods for removing eyelid nevus are associated with a risk of developing such side effects as scarring or loss of eyelashes. Although current laser modalities have shown promising results, eyelid laser surgery may cause skin discoloration and noticeable scarring. This study aims at evaluating the efficacy and safety of the dual-wavelengths copper vapor laser (CVL) treatment of eyelid intradermal nevus of Miescher (NM). Patients and Methods: We present three adult female patients with eyelid intradermal nevus treated with CVL. CVL settings were as follows: the average power of 0.6-0.8 W, under a power ratio of 3:2 at wavelengths of 511 nm and 578 nm, exposure time of 0.3 seconds, the light spot diameter of 1 mm. Results: The dual-wavelength CVL treatment of medium- and large-sized NM provides the complete removal of eyelid dome-like NM after one and two sessions with a month interval correspondingly. The duration of skin healing accounted for two weeks. Conclusion: The complete removal of eyelid NM lesions without side effects demonstrates the safety and efficacy of dual-wavelengths CVL in treating such skin lesions. This laser treatment mode of benign skin neoplasms seems promising for dermatologists and cosmetologists’ clinical practice.

Introduction. Speckled lentiginous nevus or Nevus Spilus (NS) is a congenital or acquired melanocytic nevus. NS appears as dark hyperpigmented macules or papules interspersed in the lentigo-like hyperpigmentation patch. Surgical methods for removing NS, primarily on the skin with a thin dermis, are associated with the risk of disruption of its structure or scarring. The use of single wavelength laser irradiation allowed achieving pronounced bleaching of the NS area with such side effects as scars, post-inflammatory hyperpigmentation, and relapses in some cases. Side effects could occur due to the lack of complete blood flow in the microvascular bed near the NS. The study aimed to evaluate the efficacy of NS treatment with a dual-wavelength copper vapor laser (CVL). Description of patients and the method of the treatment. Two fair-skinned adult female patients with NS, of medium size and different location, asked to restore the natural colour of the skin in order to get rid of cosmetic defects. NS treatment was carried out using CVL (Yakhroma-Med model, P.N.Lebedev Physical Institute of the Russian Academy of Sciences) during six procedures, an interval of 46weeks. For treatment, we used two-wavelength CVL radiation with average power in the range of 0.60.8W with a power ratio of 3:2 at wavelengths of 511 nm and 578 nm; exposure time: 0.20.3 s. The diameter of the light spot on the skin accounted for 1 mm. Both patients were satisfied with the result of the treatment due to the noticeable blanching of the pigmented skin area after the NS removal. During the following two years, no dark spots or scarring was observed at the NS removal site. Conclusion. Treatment of medium-sized NS using two-wavelength CVL radiation made it possible toeliminate the cosmetic defect without side effects.

Frequent Reason

Acquired melanocytic nevi in aesthetically significant areas, especially palpebral nevi (PN), are becoming a frequent reason for patients to seek dermatologists. Surgical methods for removal of PN are reported to be associated with the risk of such side effects as scars and loss of eyelashes. Aim of the study. To evaluate the efficacy of the removal of PN on the eyelid area with dual-wavelength radiation of a copper vapor laser (CVL). Patients and methods. Laser removal of medium and large-sized PN (up to 10 mm) was performed in three fair-skin female patients. The procedures were carried out at an average CVL radiation power of 0.60.8 W, at a 3:2 ratio of radiation powers at wavelengths of 511 nm and 578 nm, exposure duration 0.3 s, light spot diameter 1 mm. The treatment was carried out during one session. Results. Removal of PN with dual-wavelength CVL radiation allowed achieving a significant lightening and reduction of the involved area, without scars. The skin healing after the procedure lasted 2 weeks. Conclusion. The high efficacy of the PN removing in the eyelid area using the dual-wavelength CVL radiation allows the introduction of this approach into dermatologists and cosmetologists clinical practice.

Background. Granulomas of the vermilion border of the lips (GVBL); as a complication of lip tattooing; inevitably poses cosmetic problems. Surgical excision and cryodestruction are associated with an increased risk of scarring and recurrence of GVBL. Laser therapy can selectively destroy a pigment and achieve the desired cosmetic result with minimal risk of side effects. So laser treatment was reported to be a more relevant method of treatment of GVBL. Aim. To evaluate the effectiveness of treatment of GVBL with copper vapor laser (CVL) radiation. Case report. 39-year-old female patient; without manifestations of systemic sarcoidosis; reported a 2-year history of granulomas of the lips vermilion border. She had a permanent makeup cosmetic tattoo before the onset of granulomas after lip tattooing. Histopathological examination revealed the presence of pigment in the upper and middle layers of the dermis. GVBL treatment was performed using a CVL during a single procedure; with an average CVL power of 0.60.8 W; with a ratio of 3:2 at wavelengths of 511 nm and 578 nm; exposure time 0.3 s. Light spot diameter 1 mm. CVL treatment led to a pronounced elimination of all GVBL without side effects within five years. Discussion. CVL allows a combined mode of exposure; consisting of grinding large granules of pigment to sizes that can be absorbed by the lymphatic system and suppressing VEGF expression using radiation with a wavelength of 578 nm. Conclusions. The CVL treatment provided an excellent cosmetic result due to selective photodestruction of the pigment and complete remodeling of the vascular bed associated with GVBL. The high clinical efficiency of eliminating post-tattooing foci of GVBL using CVL without side effects allows us to suggest this method for dermatologists and cosmetologists as a highly effective and inexpensive way to eliminate complications of permanent makeup.

Introduction.Congenital melanocytic nevus (CMN) is detected at birth or shortly after birth in 1% of infants. The localization of CMN in aesthetically significant areas causes a decline in child self-esteem and causes concern for his parents. Surgical excision of skin areas with CMN is associated with an increased risk of cosmetic side effects and is often followed by long-term stress conditions after the invasive intervention. Aim of the study.To evaluate the efficacy of the CMN removal in infants, children and adolescents with the dual-wavelengths copper vapor laser (CVL) radiation. Patients and Methods.Medium-sized (up to 9 cm) single CMN was treated in nine fair-skinned patients: seven girls and two boys, aged from 2 months to 16 years. The procedures were carried out at an average CVL power of 0.61.0 W, with a power ratio of 3:2 at 511 nm and 578 nm wavelengths, and an exposure time of 0.20.3 s. Light spot diameter 1 mm. The treatment was carried out during 210 sessions with an interval of 12 months between sessions. Results.In children and adolescents, the treatment of CMN with CVL dual-wavelengths radiation made it possible to achieve significant clarification of the involved area without hypertrophic scars. The duration of the healing of the irradiated area lasted 23 weeks. Side effects were manifested with subtle skin atrophy. Conclusion.The high efficacy of CVL removal of medium-sized CMN in infants and children using the dual-wavelengths CVL radiation without pronounced side effects allows introducing such an approach in the clinical practice of pediatric dermatologists and cosmetologists.
