Abstract
Melanoma is an aggressive tumor with advanced disease characterized by widespread metastatic lesions and the tumor has traditionally been resistant to most forms of treatment. Indeed, metastatic melanoma has a very poor prognosis with a median survival time of 8-9 months and an estimated 3-year survival rate of less than 15%. Recent advances in our understanding of the genetic profile of melanoma cells and the molecular factors that drive malignant transformation have resulted in the identification of numerous new therapeutic targets. KIT is an established therapeutic target in cancers with activating mutations of KIT, such as gastrointestinal stromal tumors (GIST), and considerable efficacy has been achieved with various small molecule inhibitors of KIT including imatinib mesylate. Nilotinib is an inhibitor of ligand-induced PDGFRα and PDFGRβ kinase activity and autophosphorylation of constitutively activated KIT harboring exon 13 or exon 11 mutations (IC50 values of 0.2 and 0.027 μmol/L, respectively), with efficacy comparable to that of imatinib. We report a case of non-kit mutated metastatic vaginal melanoma showing impressive response to nilotinib.

Abstract
In contrast with bone metastasis, acrometastases are uncommon and are associated with advanced cancer. We report the cases of two patients with atypical lesions of the fingers in a context of cancer, in which biopsies confirmed a metastasis. Patients died rapidly before treatment was initiated. We discuss the characteristics of these atypical metastatic sites, associated with a generally poor prognosis.

Abstract
Variations in the clinical and histological presentation of cutaneous T-cell lymphoma (CTCL) can hamper diagnosis. We report two cases of a novel presentation of CTCL characterized by an aberrant immunophenotype with complete loss of pan T-cell antigens including T-cell receptor β chain and showing the clinical and histopathological appearance of erythrodermic and plaque-stage mycosis fungoides.

Abstract
BACKGROUND Some prognostic markers of venous leg ulcer (VLU) healing have been evaluated, mostly in retrospective studies. OBJECTIVES To identify which clinical characteristics, among those known as possible prognostic factors of VLU healing, and which VLU-associated sociodemographic and psychological factors, are associated with complete healing at week 24 (W24). METHODS A prospective, multicentre, cohort study was conducted in 22 French dermatology departments between September 2003 and December 2007. The end point was comparison between healed and nonhealed VLUs at W24, for patient clinical and biological characteristics; psychological, cognitive and social assessments; affected leg inclusion characteristics; venous insufficiency treatment and percentage of initial wound area reduction during follow-up. RESULTS In total, 104 VLUs in 104 patients were included; 94 were analysed. The mean VLU area and duration were 36.8 ± 55.5 cm2 and 24.8 ± 45.7 months, respectively. At W24, 41/94 VLUs were healed. Univariate analysis significantly associated complete healing with superficial venous surgery (P = 0.001), adherence to compression therapy at W4 (P = 0.03) and W24 (P = 0.01), ankle-joint ankylosis (P = 0.01) and mean percentage of VLU area reduction at W4 (P = 0.04). Multivariate analysis retained superficial venous surgery during follow-up [odds ratio (OR) 8.4, 95% confidence interval (CI) 1.9-48.2] and percentage reduction of the VLU area at W4 (OR 1.6, 95% CI 1.0-2.14) as being independently associated with healing. CONCLUSIONS These results indicate that complete healing of long-standing, large VLUs is independently associated with ablation of the incompetent superficial vein and percentage of wound area reduction after the first 4 weeks of treatment.
