Tattooing for ornamental purposes is an ancient practice that remains popular in modern times. Tattoos are encountered by the dermatopathologist either as incidental findings on skin biopsies or because of complications specific to the tattoo. A range of neoplasms and inflammatory conditions are seen in association with tattoos, many of which may be attributed to hypersensitivity to tattoo inks...

BACKGROUND Amalgam tattoos result from deposition of metallic particles (eg, silver, mercury, copper, zinc, and tin) into the oral mucosa. Their clinical and histologic appearance is similar to that of decorative tattoos. OBJECTIVE To describe the successful use of a Q-switched alexandrite laser for removal of an amalgam tattoo. MATERIALS AND METHODS An amalgam tattoo on the buccal mucosa a...

The purpose of our study was to assess the mechanical effect on tattoo seals and eye makeup caused by a spatial magnetic gradient in the magnetic resonance imaging (MRI) system. Seven kinds of tattoo seals and three kinds of eye makeup, i.e., mascara, eye shadow, and eyeliner were used. On a 3.0-Tesla MRI, we determined these deflection angles according to a method established by the American S...

An increasing number of people are getting tattoos; however, many regret the decision and seek their removal. Lasers are currently the most commonly used method for tattoo removal; however, treatment can be lengthy, costly, and sometimes ineffective, especially for certain colors. Ingenol mebutate is a licensed topical treatment for actinic keratoses. Here, we demonstrate that two applications ...

Ornamental tattooing involves the administration of exogenous pigments into the skin to create a permanent design. Our case focuses on a 62-year-old woman who presented with an inflamed enlarging nodule on her right proximal calf, which arose within the red pigment of an ornamental tattoo. The nodule was diagnosed as squamous cell carcinoma (SCC) and subsequently excised. Over the course of the...

Diffuse lamellar keratitis (DLK) is a sterile inflammation of the cornea, which may occur after laser-assisted in situ keratomileusis (LASIK) surgery. Little is known about the association of DLK with permanent eyeliner tattoo. The present case report describes the case of a 37-year-old Chinese woman who developed severe foreign body sensation in both eyes 1 week after receiving bilateral perma...

BACKGROUND Small colonic lesions which are identified during endoscopy are usually difficult to locate intra-operatively. Endoscopic tattoo of the colon seems the most efficient method, however it does fail in some cases to identify the lesion peroperatively. We studied this method to evaluate its efficacy. METHODS Nineteen patients were tattooed during colonoscopy with "India ink" (drawing i...

BACKGROUND Tattoos of natural red/brown henna obtained from the indigenous tree Lawsonnia have been traditionally performed with a few side-effects. Nowadays black henna tattoos are usually performed even in children. The addition of several chemical agents to improve its cosmetic properties has increased the risk of developing contact dermatitis after exposure. Our aim is to determine the caus...

The skin is an attractive organ for immunization because of the presence of antigen-presenting cells. Intradermal delivery via tattooing has demonstrated superior vaccine immunogenicity of DNA vaccines in comparison to conventional delivery methods. In this study, we explored the efficacy of tattoo injection of a tumor vaccine based on recombinant Semliki Forest virus replicon particles (rSFV) ...

OBJECTIVE The purpose of this UK study was to evaluate interfraction reproducibility and body image score when using ultraviolet (UV) tattoos (not visible in ambient lighting) for external references during breast/chest wall radiotherapy and compare with conventional dark ink. METHODS In this non-blinded, single-centre, parallel group, randomized control trial, patients were allocated to rece...
