Background and Objectives: Warts are benign lesions of viral etiology characterized by a hyperkeratotic appearance tending to spread across the skin surface. Various treatments have been proposed to manage this condition, such as acids, imiquimod, photodynamic therapy, cryotherapy, and various lasers. Materials and Methods: In this paper, we describe a combination protocol using CO2 laser prior to Nd:YAG laser for lesions interesting the palmoplantar areas or dye laser for lesions on other skin surfaces in the management of non-facial warts resistant to traditional therapies. In total, 34 patients with 103 warts suffering from wart infection resistant to traditional therapies treated from 1 January 2019 to 1 June 2020 were retrospectively enrolled at the Dermatological Unit of Magna Graecia University (Catanzaro, Italy). Two dermatologists measured clinical results, classifying lesions with complete resolution, partial resolution, or non-responding. Patients at four months follow-up were asked to evaluate their degree of satisfaction with a visual analog scale (VAS). Results: Almost all patients reported the complete resolution of lesions, with no patient reporting scarring. Five patients reported hypopigmentation in the treated areas. The mean satisfaction level was high. Only three patients experienced a relapse of the condition. Conclusions: Using a vascular laser following a CO2 superficial ablation of warts may help reduce the risk of scarring and decrease the incidence of relapses for lesions resistant to traditional therapies. Therefore, more extensive studies will be necessary to confirm the obtained results.

Background and Objectives Granular myringitis is troublesome for otologist because uncertain etiology and often been overlooked due to vague clinical symptoms and signs. The ideal treatment is elusive. Our study was to investigate the clinical characteristics of granular myringitis and analyzing the effect of the two different strategies, including carbon dioxide laser (CO2 laser) and caustic agent cauterization to manage granular myringitis. Study Design: Retrospective review Subjects and Methods One hundred and thirty patients with granular myringitis receiving treatment at a single medical center from July 2009 to January 2018 were enrolled. We retrospectively reviewed the charts and surgical records. The main two different strategies to manage focal refractory granular myringitis were analyzed, including carbon dioxide laser and caustic solution. We also recorded the clinical course and determine which strategy is better. Results One hundred and thirty patients with granular myringitis were enrolled. 47/130 (36.1%) had previous otologic procedures. Frequent ototrrhea is the most common symptom (66.1%). Posterior-inferior quadrant is the most common site of involvement (58%). The successful rate of CO2 laser, caustic agent were 94.9% and 79.2%. The recurrence rate was comparable between CO2 laser and caustic agent. No major complication was found in either individual group. Conclusion: Otologic procedure may be a predisposing factor of focal chronic myringitis. Ear drops had poor efficacy compared to other treatments. It can be apply only on minor and fresh symptom cases. In this study, we suggest CO2 laser can be the first line treatment, especially for the troublesome or refractory GM cases, which had the higher successful rate and less complication comparing to caustic agent cauterization.

Introduction: Acne vulgaris is a common disease affecting pilosebaceous unit that can lead to significant scarring. Fractional CO2 Laser and microdermabrasion are effective non-surgical treatment modalities for acne scars. Aims and objectives: To study and compare the efficacy of fractional CO2 Laser and microdermabrasion therapy in acne scars. Material and methods: Total 100 patients were selected in our study. 50 patients were allotted into each group. Scar grading assessment was done by Goodman and Baron qualitative scar grading system. Result: 50 patients were taken in each group. There was a significant improvement in grading of acne scars at the end of 6months of treatment. On comparison of fractional CO2 Laser with microdermabrasion, p-value was <0.05 that is significant. Conclusion: Fractional CO2 Laser showed better improvement in grading of acne scars then microdermabrasion, though none of these treatments are 100% effective in treating acne scars. Keywords: Acne scars, fractional CO2 laser, microdermabrasion, Goodman and baron grading.

Sir, Porokeratosis is a group of cutaneous diseases presented by epidermal keratinization [1]. Herein, we report the case of a patient with porokeratosis who responded well to carbon dioxide (CO2) laser therapy. A 22-year-old Vietnamese male visited our department with an asymptomatic plaque on the penis present for three months. He denied a family history of similar lesions. A cutaneous examination of the penis revealed an annular, well-circumscribed plaque with slightly raised borders with scales (Fig. 1a). Other mucocutaneous lesions were absent. Fungal microscopy, a rapid plasma reagin (RPR) test, and a Treponema pallidum hemagglutination (TPHA) test were negative. Histological findings revealed a hyperkeratotic lesion with a discrete parakeratotic column. There was the presence of a cornoid lamella, which was a parakeratotic column overlying a small vertical zone of dyskeratotic and vacuolated cells within the epidermis (Fig. 2a). There was also a focal loss of the granular layer. A mild lymphocytic infiltrate could be seen around an increased number of capillaries in the underlying dermis (Fig. 2b). CO2 laser removal was performed. There was no recurrence after a twelve-month follow-up (Fig. 1b). However, a hypopigmented scar was seen. Porokeratosis is an uncommon disorder of keratinization with clinical variants, such as classical porokeratosis of Mibelli, disseminated superficial actinic porokeratosis, linear porokeratosis, and porokeratosis palmaris et plantaris disseminata [2]. Porokeratosis involving the genital areas and other adjacent sites is rare [2]. Genital porokeratosis was first described by Helfman in 1985 [3]. More than 69 cases have been reported in the literature [1]. The pathophysiology of genital porokeratosis remains unknown. It has been supposed that porokeratosis is linked to repeated minor frictional trauma. A benign lesion may transform into squamous cell carcinoma or basal cell carcinoma [4]. However, no malignant transformation of genital porokeratosis has been noted in the literature. Genital porokeratosis manifests itself clinically as classic or plaque-type porokeratosis of Mibelli [2]. Histological findings revealed a cornoid lamella with the absence of a granular layer and dyskeratotic cells in the upper spinous zone [2]. Our case may mimic some annular lesions, such as secondary syphilis, fungal infection, and annular lichen planus. Because a fungal examination and syphilis serology were negative, we could exclude fungal infection and annular secondary syphilis. The distinctive histology of porokeratosis such as a cornoid lamella with a decreased granular layer may help to differentiate between porokeratosis and annular lichen planus [4]. Numerous therapeutic methods of treatment exist, including surgical excision, CO2 laser, cryotherapy, topical retinoids, 5% 5-fluorouracil, vitamin D3 analogs, imiquimod cream, and 3% diclofenac gel [2,5].
