Here we describe a new mouse model that exploits the pattern of expression of the high-affinity IgG receptor (CD64) and allows diphtheria toxin (DT)-mediated ablation of tissue-resident macrophages and monocyte-derived cells. We found that the myeloid cells of the ear skin dermis are dominated by DT-sensitive, melanin-laden cells that have been missed in previous studies and correspond to macrophages that have ingested melanosomes from neighboring melanocytes. Those cells have been referred to as melanophages in humans...

Bottlenose dolphins are excellent bioindicators of ocean ecosystem health for three reasons: (a) as long-lived apex predators they accumulate biotoxins and contaminants; (b) they are visible, routinely appearing at the water's surface in coastal areas, often coming into close contact with humans; and, (c) they exhibit a range of pathogenic lesions attributable to environmental degradation. In this study, we analyzed tattoo-like skin lesions in a population of Tursiops aduncus studied for 30+years in Shark Bay, Australia, a UNESCO World Heritage Site...

The pathogenesis, diagnosis and therapy of sarcoidosis as an autonomous disease are subjects of spirited discussions, which haven't found definitive conclusion yet. Distinguishing between sarcoidosis and sarcoid-like reactions (sarcoid - type granulomas) is not currently a medical "gold standard" and is not implemented in clinical practice. This leads to 1) misinterpretation of numerous available data; 2) difficulty in the interpretation of other unverified data, which is often followed by 3) inappropriate or inadequate therapeutic approach...

Background and aims: The selective removal of tattoos and benign cutaneous pigmented lesions with laser energy evolved rapidly with the development of the nanosecond-domain Q-switched laser (ns-laser). Recently, however, a series of picosecond-domain lasers (ps-lasers) with pulsewidths less than 1 ns has become commercially available, enabling more efficient and faster removal of pigmented lesions in the field of dermatologic laser surgery. Rationale behind the ps-laser: The efficacy of the ns-laser depended on the theory of selective photothermolysis, whereby an extremely short pulse width was delivered less than the thermal relaxation time (TRT) of a target...

Few reports describe tattoo granulomas with the simultaneous development of intraocular inflammation without any evidence of systemic sarcoidosis at the time of presentation. Here, we present a patient with no prior diagnosis of sarcoidosis who developed inflammation of tattooed skin and shortly after bilateral uveitis.A 52-year-old previously healthy woman presented with a 8 months history of swelling and itching located in all of her 11 black tattoos. Approximately 5 months later she developed complaints of blurred vision, diagnosed as recurrent uveitis anterior by an ophthalmologist...

AIMS: Tattooing and use of permanent makeup (PMU) has dramatically increased over the last decade, with a concomitant increase in ink-related infections. The aim of this study was to determine whether microorganisms are present, and if so, the number and their identification, in the commercial tattoo and PMU inks available in the United States. METHODS AND RESULTS: We surveyed 85 unopened tattoo and PMU inks, purchased from 13 companies. We incubated 100 μL of ink samples on trypticase soy agar plates for bacterial growth, 7H10 Middlebrook medium for mycobacterial growth, and Sabouraud dextrose medium for fungal growth...

Clinical and epidemiological features of tattoo skin disease (TSD) are reported for 257 common bottlenose dolphins held in 31 facilities in the Northern Hemisphere. Photographs and biological data of 146 females and 111 males were analyzed. Dolphins were classified into three age classes: 0-3 years, 4-8 years, and older than 9 years. From 2012 to 2014, 20.6% of the 257 dolphins showed clinical TSD. The youngest dolphins with tattoo lesions were 14 and 15 months old. TSD persisted from 4 to 65 months in 30 dolphins...

INTRODUCTION: Tattooing is a very popular form of body modification among young people. However, this kind of procedure entails the risk of various health complications. The objective of the study was to evaluate the students' knowledge about contraindications, complications, and health risks that skin tattooing may cause. Additionally, the purpose of the study was to assess how the profile of education (medical vs nonmedical) impacts on the knowledge of the respondents. METHODS: We surveyed a group of 1199 people, of which 326 (27%) had tattoos...

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 following year, the patient was diagnosed with a total of five additional SCCs that also arose within the red pigment of the tattoo...

This review describes the use of picosecond lasers for the treatment of tattoos, pigmented lesions, scars, and their use in rejuvenation. These devices have delivered enhanced efficacy for the treatment of tattoos and pigmented lesions when compared to the older 40-50 nanosecond devices. The fractional delivery with the picosecond devices have opened up a new method of rejuvenation for photodamaged skin and the treatment of scars. The delivery of these high-energy short pulses have created zones of injury in the skin referred to as areas of laser-induced optical breakdown...

The majority of oral pigmentations are benign lesions such as nevi, melanotic macules, melanoacanthomas or amalgam tattoos. Conversely, mucosal melanomas are rare but often lethal; therefore, excluding oral melanomas in this setting is crucial. Reflectance confocal microscopy is a non-invasive, in vivo imaging system with cellular resolution that has been used to distinguish benign from malignant pigmented lesions in the skin, and more recently in the mucosa. However, lesions located posteriorly in the oral cavity are difficult to assess visually and difficult to biopsy due to their location...

Many mainstream medications were derived from plants and originally utilized in patient management well prior to the extensive research and testing processes of current pharmaceutical standards. The evolution of therapeutic management within the pharmaceutical and skin care industry often uses synthetic processing of products with less of a focus on the natural ingredients from which they were originally derived. However, more recently there has been a shift in pharmacological management to include the therapeutic use of more holistic medicines and practices and thus a broadening of the uses of nontraditional medical treatment options...

The picosecond lasers have shown to effectively treat tattoo pigments that are intractable to previous multiple Q-switched (QS) laser treatments. Therefore we hypothesized that a picosecond laser would show better efficacy with minimal adverse events in the treatment of melasma and post-inflammatory hyperpigmentation (PIH) that are difficult to treat with conventional QS lasers. Two patients with melasma and one patient with PIH were treated with a Picosecond 755-nm Alexandrite Laser (Cyanosure, USA). All patients were Korean with skin type IV and no longer responding to QS laser treatments...

INTRODUCTION: Tattooing has become a popular practice in western countries, particularly among younger populations. Tattoos, however, can cause complications, such as infections, allergic or foreign-body reactions, and even systemic inflammatory responses. PATIENTS AND METHODS: We conducted a retrospective study of all patients seen for tattoo-related complications at our skin allergy unit between January 2002 and December 2016. RESULTS: We studied 23 patients...

During oestrus, fattening female pigs are more prone to lameness, fractures and wounds due to mounting and agonistic behaviours of penmates. This study assessed the effect of sexual maturity on the behaviour and welfare of heavy female pigs slaughtered at 36 weeks of age (180±10 kg) for dry-cured ham production. An immunocastrated control group was used for comparison. In all, 56 15-week-old female pigs, individually identifiable by back tattoos were equally distributed among four pens. All animals from two pens were subject to a three-dose immunocastration schedule at 16, 20 and 32 weeks of age...

OBJECTIVE: Permanent hypopigmentation of burn scars is a common consequence after partial and full thickness burns that heal by secondary intent, and they can cause severe aesthetic issues. The surgical goals for effective treatment of postburn hypopigmentation are to remove scar tissues, and to produce healthy melanocytes, with minimal donor site morbidity. This article reviews the current literature about the different ways to treat hypopigmentation following burn injuries and discusses the indications...

A 31-year-old man developed a fast-growing tumor on the right upper arm within a black tattoo, which could be classified histologically as pilomatrixoma. While the age of the patient and the rapid growth of the tumor cannot be regarded as typical findings of pilomatrixomas, the localization on the upper arm is one of their predilection points. Despite the wide spread use of tattoos in the last few decades, tumor development in tattooed skin is rarely reported. It is still controversial whether the ingredients of the tattoo agents can be responsible for tumor induction...

BACKGROUND: Increasing numbers of reports of rapidly arising, isolated or eruptive keratoacanthomas (KA) and squamous cell carcinomas (CSC) on the red part of tattoos tend to suggest a non-fortuitous link with the procedure. We report herein two different presentations of KAs on tattoos: one patient with multiple eruptive KAs on sun-exposed areas of a recent red tattoo and another with a solitary lesion on a recent tattoo. We discuss the issues related to the distinction between KAs and CSCs in this particular context...
