[Complications related to tattoo practice].

Complications related to tattoo practice. Tattooing can result in a wide variety of complications, whose prevalence and incidence remain still unclear. Hypersensitivity reactions (or allergies) to tattoo pigments are currently the most common complication on a tattoo, however are not predictable.

Laser treatment of hyperpigmented lesions: position statement of the European Society of Laser in Dermatology.

Background: Lasers and intense pulsed light sources (IPLS) are proposed for the treatment of many pigmentary disorders. They are sometimes considered as magic tools able to remove any type of lesions. Although being the best option for several hyperpigmented lesions, they can also worsen some conditions and have potential side-effects.

Treatment of granuloma annulare with the 595-nm pulsed dye laser, a multicentre retrospective study with long-term follow-up.

Background: Granuloma annulare (GA) is limited in most cases to isolated lesions, but more widespread generalized forms can be observed. In both cases, the treatment remains highly challenging. Isolated case reports suggested the interest of treating GA with a pulsed dye laser (PDL).

Nevus of Ota in dark skin--an uncommon but treatable entity.

Background: Nevus of Ota can be effectively and safely treated since the arrival of q-switched lasers in dermatology. However, available literature is scarce regarding the treatment of Nevus of Ota in skin types darker than IV.

Objectives: We report about four Fitzpatrick phototype V patients treated for Nevus of Ota with a q-switched Nd:YAG laser at 1,064 nm.

Cutaneous lymphoid hyperplasia (pseudolymphoma) in tattoos: a case series of seven patients.

Background: Cutaneous lymphoid hyperplasia (CLH or pseudolymphoma) is considered a rare complication occurring in tattoos. We analysed the demographics, clinical features, histological aspects, allergy tests, outcome and therapeutic data of CLH in tattoos performed by a professional in a series of patients.

Methods: We conducted a retrospective chart review of seven patients managed in private practice of dermatology all over France from 2001 to 2007.

Treatment of xanthelasma palpebrarum by 1064-nm Q-switched Nd:YAG laser: a study of 11 cases.

Background: Xanthelasma palpebrarum (xanthelasma) is a common disease involving the eyelids. It consists of yellowish plaques of esterified cholesterol situated in the middle and superficial layers of the dermis. Many techniques, including laser treatments, have been proposed to destroy these lesions.

[Bowen disease treated with scanned pulsed high energy CO2 laser. Follow-up of 6 cases].

Introduction: Cutaneous Bowen's disease is an intra-epidermal squamous cell carcinoma.

Patients And Method: Ten cases of cutaneous Bowen's disease diagnosed among 8 patients were treated by scanned high energy carbon dioxide laser between November 1996, and March 1998. A biopsy was performed in all patients before treatment.

Treatment of gunpowder traumatic tattoo by Q-switched Nd:YAG laser: an unusual adverse effect.

Background: The Q-switched Nd:YAG laser can completely eliminate traumatic tattoos.

Objective: We report the results of the unsuccessful removal of traumatic tattoos among three patients with dermal inclusions of gunpowder who were shot at close range.

Methods: Treatment was tried in each patient with a Q-switched Nd:YAG laser at a medium fluence (4-6 J/cm2).

[Langerhans-cell histiocytosis in twin sisters].

BACKGROUND--Histiocytosis of Langerhans cells includes a range of clinical manifestations that have been described as bone eosinophilic granuloma, Hand-Schüller-Christian syndrome, Letterer-Siwe syndrome and Hashimoto-Pritzker histiocytosis. These syndromes represent a spectrum of severity and prognosis of the same underlying disorder which is usually sporadic. It has occurred in monozygotic twins and in a familial pattern.

Subcutaneous changes in dermatomyositis.

We report the case of a 42-year-old woman with concomitant panniculitis and dermatomyositis. Painful, indurated lesions on the buttocks, thighs, arms, abdomen and breasts were associated with proximal muscle weakness. Skin biopsy revealed lobular panniculitis, and vacuolar degeneration of epidermal basal cells.

[Metastatic basal cell carcinoma].

A case of basal cell carcinoma in a 17-year old male patient complicated, 5 years later, by inguinal and pulmonary metastases is reported. This clinical case raises two problems: the reality of the entity and the long-term follow-up of this type of tumours.

[Cutaneous and nail infections caused by Hendersonula toruloidea].

A case of cutaneous and nail infection due to Hendersonula toruloidea (HT), in a Senegalese woman who had been living in France for 7 years is reported. This patient presented with keratotic lesions of the palms and distal and lateral onycholysis. Culture of clinical specimens on Sabouraud's medium without cycloheximide resulted in the isolation of HT.

[Cutaneous metastasis disclosing primary angiosarcoma of the aorta].

A 68-year old man presented with erythemato-telangiectatic nodules on his right lumbar fossa, associated with right-sciatica. A skin biopsy was performed. Microscopic examination showed tumour embolism in the lumen of the dermal vessels.
