Morphological features of naevoid melanoma: results of a multicentre study of the International Dermoscopy Society.

Background: Naevoid melanoma (NeM), a rare variant of melanoma, can be difficult to detect as its clinical and histopathological morphology can simulate a naevus.

Objectives: To describe the clinical and dermoscopic features associated with NeM.

Methods: Lesions with a histopathological diagnosis of NeM were collected via an e-mail request sent to all members of the International Dermoscopy Society.

[Sneddon-Wilkinson disease: efficacy of intermittent adalimumab therapy after lost response to infliximab and etanercept].

Background: Sneddon-Wilkinson disease (SWD) is a rare chronic neutrophilic dermatosis. The first-line treatment is dapsone but resistance to treatment may sometimes pose a challenge.

Case Report: We report a multidrug-resistant patient who responded dramatically before gradually losing response to infliximab and then etanercept.

[595 nm pulse dye laser therapy for viral warts: a single-blind randomized comparative study versus placebo].

Introduction: Pulse dye laser (PDL) appears an attractive method to treat warts. However, data concerning the efficacy of this approach are based chiefly upon open clinical studies or case reports and results vary widely from one study to another. The purpose of this study was to compare the efficacy and safety of PDL with a placebo in the treatment of a homogeneous group of patients presenting palmoplantar warts.

Clinical variants of the preprotuberant stage of dermatofibrosarcoma protuberans.

Background: Some cases of dermatofibrosarcoma protuberans (DFSP) do not protrude above the skin.

Objectives: To assess the prevalence of these DFSPs and further to describe their presentation and course.

Methods: One hundred and forty-three patients were retrospectively collected.
