Ritual and artistic tattoos rely on the use of numerous pigments which are not all entirely inert once placed in the dermis. The compositions of some tattoo inks are identified. However, new but less well identified compounds appear on the market. Allergic reactions can be present under different aspects. They may correspond to allergic contact dermatitis or to photodermatitis. Other reactions include allergic hypersensitivity reactions as well as lichenoid, granulomatous or pseudolymphoma reactions. Pulsed light and laser are typically used for regular tattoo removal. These procedures are not indicated in inflamed tattoos. Indeed, the pigment dispersed during photolysis may perpetuate the reaction. Pseudotattoos due to the stratum corneum staining are frequently responsible for photoeczema. [less ▲]

Sun is at the origin of life and is responsible for death as well. In the past decades cutaneous melanoma has affected more and more young adults. In the White population, sun exposures and sunbeds are pointed out as the main culprits responsible for addictive behaviour. Preventive measures to be taken aim at avoiding the effects of ultraviolet light addiction. Sunlight exposure particularly in moderation is indeed beneficial through vitamin D3 synthesis and improved psychological wellbeing. Hence, we are facing the dilemma between too much and too little ultraviolet light exposure.In the Black population, the reverse situation is prevalent. It concerns skin depigmentation which may turn out to be a caricature in some subjects. [less ▲]

Malignant melanoma developed after 60 years of age is not a rare neoplasm. It is mainly but not exclusively represented by the lentigo maligna (LM) and the invasive melanoma developed on LM (LMM). Men are more often affected, and chronic sun exposure is the main cause. The diagnosis relies on the clinical, dermoscopic and dermatopathologic examinations. Surgical excision is recommended but alternative treatments are possible in case of contra-indication. [less ▲]

Acne is a domain in which the technology and understanding of light/laser therapeutic procedures have advanced considerably. The aim of the paper was to revisit adjunctive physical treatments of acne, including light/laser treatments and photodynamic therapy. This review summarizes findings about such treatment modalities with particular emphasis on efficacy and safety. A number of laser/light-based modalities have been developed to meet the increasing demand for new acne treatments. The current devices correspond, on the one hand, to light-emitting diode therapy and, on the other hand, to the 532-nm potassium titanyl phosphate laser, the 585- and 595-nm pulsed dye laser, the 1450-nm diode laser, the 1320-nm Nd:YAG laser and intense pulsed light. Photodynamic therapy is also available. It is claimed that light/laser treatments might induce a faster response compared with the 1-3 months needed for response to traditional oral and topical treatments. In conclusion, pulsed dye laser shows efficacy in some patients with mild to moderate acne. The relative effectiveness compared with other treatments is unconfirmed; from the published information, evidence-based efficacy assessment of light/laser therapies in acne remains almost impossible.

Des effets cutanés indésirables peuvent survenir lors de chimiothérapies anticancéreuses. La morbidité peut être handicapante à des degrés divers. Certaines manifestations sont graves comme celles rencontrées lors de nécroses épithéliales et/ou vasculaires étendues. D’autres sont spécifiques à l’agent administré. Tel est le cas pour des éruptions acnéiformes induites par les antagonistes de l’EGFR. Dans la grande majorité des cas, les altérations de la structure de la couche cornée et de ses fonctions se résument seulement à un état de xérose. Parfois aussi, les altérations ne se décèlent qu’à l’examen histopathologique sans répercussion clinique manifeste. Pour chaque patient concerné, il convient d’identifier avec précision les effets indésirables de la chimiothérapie anticancéreuse afin de choisir les moyens les plus adéquats pour prévenir leur aggravation et les traiter au mieux. L’apport de l’examen dermatopathologique standard et fonctionnel est précieux au stade du diagnostic. [less ▲]

Malignant melanoma (MM) micrometastases are basically seen in three locations inside the peritumoral dermis. They are localized (i) inside the interstitial sector of the dermal stroma; (ii) abutted to the external surface of the microvasculature; and (iii) more rarely present inside vascular channels. Single-cell and paucicellular micrometastases may be disclosed using immunohistochemistry even in the absence of larger microsatellites, which represent micronodular nests of metastatic cells. The presence of microsatellites is frequently tied to markers of MM aggressiveness including thickness and the Ki-67 index. Micrometastases may be present in the same conditions, but even as early as thin MM showing a small growth fraction. Microsatellites as well as micrometastases appear to predict locoregional extension and decreased relapse-free interval, but not distant metastasis and overall survival. These considerations have implications for patient care since patients with microsatellites and micrometastases are now included in the clinical stage III category of the disease. Their implication as a prognostic factor is not fully dependent on or linked to other markers of MM aggressiveness. [less ▲]
