Currently ablative fractional photothermolysis (aFP) with CO2 laser is used for a wide variety of dermatological indications. This study presents and discusses the utility of aFP for treating oncological indications. We used a fractional CO2 laser and anti-PD-1 inhibitor to treat a tumor established unilaterally by the CT26 wild type (CT26WT) colon carcinoma cell line. Inoculated tumors grew significantly slower in aFP-treated groups (aFP and aFP + anti-PD-1 groups) and complete remission was observed in the aFP-treated groups...

Shivani B Kaushik, Andrew F Alexis
Background: Nonablative laser resurfacing represents one of the major advances in procedural dermatology over the past decade. However, its use in darker skin types is limited by safety concerns and a relative lack of available data. Aim: To provide evidence-based recommendations for the use of fractional lasers in darker skin types. Evidence review: A broad literature search of PubMed/Medline database was conducted in April 2016 using the term fractional lasers. A free text search of keywords including fractional resurfacing, nonablative lasers, skin type, skin of color, ethnic skin, Fitzpatrick skin type, Asian skin, African Americans, Afro-Caribbean, and Hispanics was also executed...

In addition to dermoscopy, there are other imaging and biophysical methods for the noninvasive diagnosis of skin lesions. Confocal laser microscopy allows for high-resolution imaging of the epidermis and upper dermis. It is particularly suitable in the differential diagnosis of melanocytic lesions. Optical coherence tomography (OCT) has a lower resolution compared to confocal laser microscopy but a greater depth of penetration. It is primarily used for imaging epithelial skin cancer, especially in the context of monitoring the effectiveness of nonsurgical therapies...

With laser surgery, what you see is what you get. Visualizing the target for treatment, be it a port-wine stain, a cluster of spider veins, a tattoo or freckles, or simply photodamaged skin requires seeing through surface reflections, dry skin, and often quite dark laser goggles. The tool that has been indispensable to me in my practice is the Syris v900L polarizing and magnifying headlamp. This indispensable tool makes laser treatment more precise, effective, and easier by truly shining a light on the subject of a laser treatment...

Dear Editor, Molluscum contagiosum (MC) is a very common skin infection caused by a molluscipox virus gene of the poxvirus family. It usually occurs in young children, sexually active adults, and immunocompromised individuals. The typical clinical picture of this infection is characterized by asymptomatic flesh-colored, single or multiple papules, measuring 2-6 mm in diameter with a central umbilication that occur on the skin and the mucous membranes. In adults, the skin lesions are predominantly located in the genital region, whereas in children they are found on the trunk, the extremities, and the face...

Rhinophyma, a rare and progressive disfiguring condition, is thought to be the final stage of rosacea. Several surgical treatments are available, including dermabrasion, cryosurgery, scalpel excision, electrosurgery, and carbon dioxide laser. The last 2 techniques are the most effective for the management of rhinophyma. We describe a series of cases of moderate or severe rhinophyma treated with high-frequency electrosurgery in the dermatology department of Hospital Simón Bolivar and in private clinics in Bogota, Colombia, between 2012 and 2016...
