Tattoo??removal a??the artistic state of the art.a?? Tattoo on forehead, nose, and chin: Successful removal with modified R20 technique using low-fluence Q-switched Nd YAG laser: A case report
摘要： Background: Tattooing is an ancient practice that has been performed all over the world which is used to beautify the skin and augment beauty. Regrettable tattoos are treated with Q switch lasers, in many sessions, and the effectiveness is doubtful. Objectives: The aim of this paper is to demonstrate how a unique protocol of R20 Q switch Nd YAG laser, can be employed successfully in removing long standing facial tattoos, in skin type IV, in an effective disciplined timing and cost wise modalities. The adopted method was a-4 single passes, with 20 minutes gap respectively. Methods and Results: A lady received the conventional Q switch laser at one session, with no noticeable results. On the other session, she received the R20 method, and an immediate whitening reaction was observed. No adverse reactions were noted. Conclusion: The R20 Q technique is very effective tool in a single treatment session than the conventional multiple laser sessions, in tattoo removal, and I would invite other dermatologists utilize it in their clinical setting. This method does not need any newer laser technology, clears the tattoo fast, and cuts down unnecessary treatment duration and cost.

Increased Tattoo Fading in a Single Laser Tattoo Removal Session Enabled by a Rapid Acoustic Pulse Device: A Prospective Clinical Trial
摘要： Background and Objectives: The ability to provide improved tattoo fading using multiple laser passes in a single office laser tattoo removal session is limited. In part, this is due to the loss of laser effectiveness caused by epidermal and dermal vacuole “whitening” generated during the initial laser pass at the tattoo site. The Rapid Acoustic Pulse (RAP) device generates acoustic shock wave pulses epidermal and dermal vacuoles to enable multiple laser passes in a single office laser tattoo removal session. The objectives of this study were to determine if the RAP device, when used as an accessory to the 1064 nm Nd:YAG Q‐switched (QS) laser can enable delivery of multiple laser passes in a single office laser tattoo removal session, and therefore result in increased tattoo fading compared to the clinical standard single‐pass QS laser tattoo removal session. Study Design/Materials and Methods: The RAP device was evaluated in a single‐center (SkinCare Physicians), prospective, IRB approved study. A total of 32 black ink tattoos, from 21 participants, were divided into three zones and treated with either multiple QS laser passes, each followed by 1 minute of RAP device application (Laser + RAP) in zone one and single‐pass QS laser treatment (Laser‐Only) in zone two, separated by an untreated control zone. The treatment sites were assessed for the number of laser passes and adverse events immediately, 6 weeks, and 12 weeks following the treatment session. Photographs of the treatment sites were assessed for percent fading at 12 weeks post‐treatment by three blinded reviewers. Results: When the RAP device was applied as an accessory to the QS laser in a multi‐pass laser tattoo removal treatment, an average of 4.2 laser passes were delivered in a single session, with no unexpected or serious RAP device‐related adverse events. At the 12‐week follow‐up, tattoos treated with Laser + RAP showed a statistically significant increase in average fading (44.2%) compared with tattoos treated with Laser‐Only (P < 0.01). Additionally, a significantly higher (24.8%) overall proportion of tattoos treated with Laser + RAP (37.5%) had a response of >50% fading compared with tattoos treated with QS Laser‐Only (9.4%) (P < 0.01) as well as a response of >75% fading from Laser + RAP treatment (21.9%) compared with Laser‐Only treatment (3.1%) (P < 0.05). Conclusions: The RAP device, applied as an accessory to the 1064 nm Nd:YAG QS laser, safely enables multiple QS laser treatments in a single office laser tattoo removal session by clearing the whitening caused by the previous QS laser pass. Enabling multiple QS laser passes results in a statistically significant increase in tattoo fading in a single office laser tattoo removal session compared to the clinical standard single‐pass QS laser tattoo removal session.

Multiple Squamous Neoplasms Arising in a Red Tattoo After Laser Tattoo Removal
摘要： Tattoos are common around the world, although not without risk. Tattooing may result in several complications, including infections, foreign-body and sarcoidal granulomatous reactions, delayed-type hypersensitivity reactions, keloid formation, pseudolymphomas, pseudoepitheliomatous hyperplasia, as well as koebnerization and pathergy of associated pre-existing skin diseases. Tattoos may even potentiate cutaneous neoplasms including benign growths, such as seborrheic keratoses, and malignant neoplasms, such as nonmelanoma skin cancers (NMSCs) and malignant melanoma. Although the mechanism underlying neoplasia due to tattoos is poorly understood, it has been suggested that trauma from the procedure itself, the carcinogenic potential of the dyes, or chronic inflammation could play a role. In this study, we present a case of multiple NMSCs developing within the red pigmented area of a tattoo after repeated laser tattoo removal treatments.

Eruptive Keratoacanthomas in a Red Tattoo After Treatment With a 532-nm Picosecond Laser
摘要： Decorative tattooing continues to be popular, with remorse and request for tattoo removal common in a significant percentage of the tattooed population. Tattoo removal carries complications including inflammatory reactions, infections, and malignancies. Many of these complications are reported to be more frequent in red tattoo ink, conceivably due to the inflammatory nature of the specific components of the red ink particles. Keratoacanthomas (KA) are considered a low-risk form of squamous cell carcinoma (SCC), often associated with injury such as surgery, trauma, and burns. While their association with tattoos has been reported, the eruption of KAs after attempted tattoo removal has not. We report a case of eruptive KAs after tattoo removal using a picosecond laser at an outside facility.

Combination of Dual Wavelength Picosecond and Nanosecond Pulse Width Neodymium‐Doped Yttrium–Aluminum–Garnet Lasers for Tattoo Removal
摘要： Background and Objectives: Tattoo removal by laser has been mostly performed using Q‐switched laser, which has nanosecond pulse width. In recent years, the efficacy of treatment with picosecond pulse width laser has also been reported. Study Design/Materials and Methods: Using yttrium–aluminum–garnet laser with a potassium‐titanyl‐phosphate frequency‐doubling crystal, we performed a retrospective clinical study with combination treatment using pulse widths of 750 ps and 2 ns. The number of treatments was compared with the Kirby–Desai score. Tissue changes immediately after laser irradiation at 2 ns and 750 ps were compared using an electron microscope. Results: The combination treatment using pulse widths of 2 ns and 750 ps was safe and more effective than the Q‐switched neodymium‐doped yttrium–aluminum–garnet laser treatment. Tattoo removal was possible with significantly fewer treatment numbers than the Kirby–Desai score, without adverse events. The results from the scanning electron microscope revealed that ink particles irradiated by 750 ps were more dispersed than those by 2 ns. Conclusions: The combination treatment with pulse widths of 2 ns and 750 ps and 1064 nm and 532 nm wavelengths using the neodymium‐doped yttrium–aluminum–garnet laser was safe and effective and can be a useful option for tattoo removal.

Comparative Evaluation of 15 Laser and Perfluorodecalin Combinations for Tattoo Removal
摘要： We present a case of laser tattoo removal treated with 15 different combinations using picosecond 1064 nm, picosecond 755 nm, nanosecond 755 nm, and a fractionated CO2 laser, both with and without a perfluorodecalin (PFD) patch to ascertain the most effective approach. A single lower extremity black tattoo was divided into 15 treatment sections allowing for testing of various laser and PFD combinations. Sectioned treatment was conducted until a treatment superiority was noted. After two sessions using sectioned combination treatments with a 4‐week interval clinically significant results were produced. The combination of picosecond 1064 nm, picosecond 755 nm, and a fractionated CO2 laser without the PFD patch showed superior clinical improvement over the other combinations.
