Radiotherapy is one of the main cancer treatments. It consists in irradiating tumor cells to destroy them while sparing healthy tissue. The treatment is planned based on Computed Tomography (CT) and is delivered over fractions during several days. One of the main challenges is replacing patient in the same position every day to irradiate the tumor volume while sparing healthy tissues. Many patient positioning techniques are available. They are both invasive and not accurate performed using tattooed marker on the patient's skin aligned with a laser system calibrated in the treatment room or irradiating using X-ray...

OBJECTIVES: The data regarding the health of professional tattooists is inexistent. Tattooists are usually heavily tattooed and exposed daily to body fluids and skin-to-skin contacts with customers, tattoo inks, solvents, allergens, irritants, and work for hours often in inadequate positions using vibrating tattoo machines. We analyzed the health status of active French professional tattooists. MATERIAL AND METHODS: An observational self-reported Internet survey was performed among 448 tattooists who were members of the French Tattoo Union in November 2013...

BACKGROUND/AIMS: Sarcoidosis is, from historical data, suggested to be more prevalent among patients with tattoo reactions. We aimed to evaluate this association in a systematic study. METHODS: This is a consecutive study of patients with tattoo complications, diagnosed in the "Tattoo Clinic" at Bispebjerg University Hospital in Copenhagen, Denmark, from 2008 to 2015, based on clinical assessment and histology. From the overall group of 494 tattoo complications in 406 patients, 92 reactions in 72 patients showed a papulo-nodular pattern studied for local and systemic sarcoidosis, since sarcoidosis is expected to be nodular...

Tattoos are on the rise, and so are patients with tattooed burn lesions. A proper assessment with regard to burn depth is often impeded by the tattoo dye. Laser speckle contrast analysis (LASCA) is a technique that evaluates burn lesions via relative perfusion analysis. We assessed the effect of tattoo skin pigmentation on LASCA perfusion imaging in a multicolour tattooed patient. Depth of burn lesions in multi-coloured tattooed and untattooed skin was assessed using LASCA. Relative perfusion was measured in perfusion units (PU) and compared to various pigment colours, then correlated with the clinical evaluation of the lesion...

Tattoo, a Polynesian word meaning 'to mark', is a form of body modification done by inserting indelible ink into the dermis to change its pigmentation. Tattoos are done for social, cultural, and religious purposes. It has been in existence since the 18th century and was associated with sailors, lower class individuals, and criminals. However, since the late 20th century, tattooing has undergone a redefinition and shifted to an acceptable form of expression all over the world, including Nigeria, cutting across almost all age groups and socioeconomic class...

BACKGROUND: Surgical manipulation of skin may result in undesired puckering of excess tissue, which is generally assumed to settle over time. In this article, the authors address the novel question of how this excess tissue remodels. METHODS: Purse-string sutures (6-0 nylon) were placed at the midline dorsum of 22 wild-type BALB/c mice in a circular pattern marked with tattoo ink. Sutures were cinched and tied under tension in the treatment group, creating an excess tissue deformity, whereas control group sutures were tied without tension...

We read the letter to the editor, Viral warts and seborrheic keratosis on tattoos: a review of 9 cases with great interest.(1) Dermatologists see only what they know! Once we recognized the possibility that warts might grow preferentially in black and blue tattoo dye, we collected 7 cases over a 10-year period from one solo private practice. In this report, a patient with a pre-existing viral wart on skin adjacent to a new tattoo appears to have preferentially spread onto the immunocompromised district (Ruocco, 2009)(2) created by black ink nanoparticles...

Pain is a common side-effect of dermatological laser procedures. Non-invasive anaesthetic drugs and anaesthetic procedures can be used to provide pain relief and increase patient satisfaction and treatment efficacy. However, it remains unclear which method provides the best pain relief. The objective of this systematic review was therefore to assess the efficacy and safety of non-invasive anaesthetic methods during dermatological laser procedures. A systematic literature search was conducted. Randomized and non-randomized controlled clinical trials (RCTs and CCTs) were included...

INTRODUCTION: Q-switched neodymium:YAG (Nd:YAG) lasers are reported to be gold standard for laser tattoo removal. In particular, the Q-switched Nd:YAG laser at 1064 nm is widely recognized for the removal of blue/black amateur tattoos. However, treatment modalities in Fitzpatrick Type VI skin carry a greater risk of complications including alterations in pigmentation compared to fairer skin (Fitzpatrick Type I-IV skin). Therefore, the aim of this case series was to describe with the use of the Q-Switched Nd:YAG laser, the removal of carbon-based amateur tattoos on patients with Fitzpatrick Type VI skin as an effective and safe method...

Current genetically-engineered mouse melanoma models are often based on Tyr::CreER(T2)-controlled MAPK pathway activation by the BRAF(V600E) mutation and PI3K pathway activation by loss of PTEN. The major drawback of these models is the occurrence of spontaneous tumors caused by leakiness of the Tyr::CreER(T2) system, hampering long-term experiments. To address this problem, we investigated several approaches to optimally provide local delivery of Cre recombinase, including injection of lentiviral particles, DNA tattoo administration and particle-mediated gene transfer, to induce melanomas in Pten(LoxP/LoxP);Braf(CA/+) mice lacking the Tyr::CreER(T2) allele...

Tattooing has been utilized by the medical community for precisely demarcating anatomic landmarks. This practice is especially important for identifying biopsy sites of nonmelanoma skin cancer (NMSC) due to the long interval (i.e., up to 3 months) between the initial diagnostic biopsy and surgical treatment. Commercially available tattoo pigments possess several issues, which include causing poor cosmesis, being mistaken for a melanocytic lesion, requiring additional removal procedures when no longer desired, and potentially inducing inflammatory responses...

BACKGROUND: While subepidermal skin inking as a fashion trend has rapidly gained popularity in Western societies, systemic anaphylaxis as a complication of tattooing has only been described once in refereed literature. Furthermore the previously reported case was from a patient who already suffered from severe allergies and no attempt to pinpoint the actual causes was made. CASE SUMMARY: We present the case of a 59-year-old man, who developed a progressive swelling and redness five hours after receiving a tattoo...
