Tattoo-like epidermal sensors are an emerging class of truly wearable electronics, owing to their thinness and softness. While most of them are based on thin metal films, a silicon membrane, or nanoparticle-based printable inks, we report sub-micrometer thick, multimodal electronic tattoo sensors that are made of graphene. The graphene electronic tattoo (GET) is designed as filamentary serpenti...
Tattoo is going to be a very common practice especially among young people and we are witnessing a gradual increase of numerous potential complications to tattoo placement which are often seen by physicians, but generally unknown to the public. The most common skin reactions to tattoo include a transient acute inflammatory reaction due to trauma of the skin with needles and medical complication...
With their short nanosecond pulse durations, Qswitched lasers have revolutionized the treatment of tattoos [1-3]. Nevertheless, the mechanisms for clinically observed tattoo clearance are still not well understood. Two mechanisms have been proposed: a) a thermal effect where tattoo particles are heated to sufficiently high temperatures to cause chemical changes within the particles and the surr...
The goal of this research is to use the information contained in the mechanisms occurring during the laser tattoo removal process. We simultaneously employed a laser-beam deflection probe (LBDP) to measure the shock wave and a camera to detect the plasma radiation, both originating from a high-intensity laser-pulse interaction with a tattoo. The experiments were performed in vitro (skin phantom...
DEAR EDITOR, I read with interest the recent report by Haus et al. about a patient who developed two lesions of lymphomatoid papulosis (LyP) on the red parts of a tattoo. However, their report deserves a few comments. Many reported pseudolymphomas on tattoos involve T cells or both T and B cells, and are not attributed ‘mainly’ to B cells, as described in the manuscript. To date, Sangueza et al...
W e present a case of a systemic allergic red tattoo reaction that required excision and skin grafting after failure of other therapies. Tattoos are associated with an increased risk of infection , eczema, psoriasis, hyperplasia, granulomatous reactions, and neoplasm, with red ink as the most common culprit for allergic reactions. Although artists have replaced dangerous mercury-based cinnabar ...
We report the case of a 33-year-old male who presented with a malignant melanoma on his anterior chest wall. The lesion was only found in the red ink pigment of the tattoo, as were several in-transit dermal metastases. Possible explanations include a pre-existing lesion which was seeded with red ink or the possibility of the red ink causing an inflammatory reaction leading to malignant transfor...
Eosinophilic cellulitis (Wells' syndrome) is an uncommon condition of unknown etiology. Wells' syndrome is usually seen in adulthood but very rare in childhood. Although pathogenesis of the disease is not very clear, it is a hypersensitivity reaction developing against a variety of exogenous and endogenous antigenic stimuli. Paraphenylenediamine is a strong allergen frequently used as a tempora...
