Background: Ipilimumab can result in durable clinical responses among patients with advanced melanoma. However, no predictive marker of clinical activity has yet been identified. We provide preliminary data describing the correlation between immunological parameters and response/survival among patients with advanced melanoma who received ipilimumab 10 mg/kg in an expanded access programme.

The objective was to determine historical changes in thickness, melanoma proportions and anatomical site of presentation over a 25-year period in our Department.
Methods: This was a historical retrospective study (January 1985 to December 2009).
Aim Of Study: To evaluate the feasibility of ipilimumab treatment for metastatic melanoma outside the boundaries of clinical trials, in a setting similar to that of daily practice.
Methods: Ipilimumab was available upon physician request in the Expanded Access Programme for patients with life-threatening, unresectable stage III/IV melanoma who failed or did not tolerate previous treatments and for whom no therapeutic option was available. Induction treatment with ipilimumab 10 mg/kg was administered intravenously every 3 weeks, for a total of 4 doses, with maintenance doses every 12 weeks based on physicians' discretion and clinical judgment.
The promising new class of immunomodulating antibodies directed against cytotoxic T-lymphocyte antigen-4 (CTLA-4) has been extensively tested in clinical trials and found to be active against cutaneous melanoma and other tumor histotypes. Inhibition of CTLA-4 characteristically induces well-identified side effects for which the definition "immune-related adverse events" (irAEs) has been proposed. IrAEs mainly include colitis/diarrhea, dermatitis, hepatitis, and endocrinopathies; uveitis, nephritis, and inflammatory myopathy also have been reported occasionally.

The aim of our retrospective study was to determine the existence of numerical variables regarding changes in MPSL that could be useful to differentiate early melanomas and atypical nevi. The study was carried out in two Italian dermatology Centres.
View Article and Find Full Text PDFAngiogenesis is critical in melanoma progression and metastasis and relies on the synthesis and release of proangiogenic molecules such as vascular endothelial growth factor (VEGF)-A and fibroblast growth factors (FGFs). S100A13 is a small calcium-binding protein that facilitates the release of FGF-1, the prototype of the FGF family. S100A13 is upregulated in astrocytic gliomas, in which it correlates with VEGF-A expression, microvessel density and tumor grading, and promotes a more aggressive, invasive phenotype in lung cancer-derived cell lines.

This study was designed to assess the expression of Beclin 1 and LC3 in cutaneous melanocytic lesions, in which they have not yet been investigated. In melanoma, we correlated their expression with conventional histopathologic prognostic factors.

There are only few studies on its tissue expression in human cancer and none in melanoma. We aimed at exploring this protein and its prognostic impact in cutaneous melanocytic lesions.

The association with small vessel vasculitis has been rarely reported. We report here an unusual case of WCD associated with small vessels vasculitis also describing the efficacy of Cyclosporin A treatment.

The management of unresectable metastatic melanoma is a major clinical challenge because of the lack of reliably effective systemic therapies. Blocking cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) has recently been proposed as a strategy to enhance cell-mediated immune responses to cancer, and clinical trials have demonstrated that anti-CTLA-4 therapy can produce durable outcomes with different response patterns than cytotoxic chemotherapy. We enrolled eight out of 155 patients with advanced melanoma in a multicentre phase II trial that evaluated the activity and tolerability of ipilimumab, a fully human, anti-CTLA-4 monoclonal antibody ( www.

Most studies have not characterized TILs, that are known to comprise distinct subsets, bearing different roles in the complex tumour microenvironment. Characterization of patient lymphocytes has been mainly performed in peripheral blood, that is not always representative of the local immune status.
View Article and Find Full Text PDFMacrophage migration inhibitory factor (MIF) is a widely expressed cytokine involved in various biological processes. Although MIF's functions in cancer have not been completely elucidated, its expression has usually been correlated with tumour progression and aggressiveness, and it is currently discussed as a new promising target for novel therapies. Recent studies seem to confirm its active role in melanoma pathobiology; however, its expression has not yet been extensively studied in melanocytic tumours.

A flap is a full-thickness portion of skin sectioned and isolated peripherally and in depth from the surrounding skin, except along one side, called the peduncle. A graft is a section of skin, of variable thickness and size, completely detached from its original site and moved to cover the zone to be repaired.

Unlike other palmoplantar keratodermas, no association with visceral or skin cancer has ever been reported.
Objective: We report a case of malignant melanoma arising in the hyperkeratotic lesions on the right heel of a patient with striated palmoplantar keratoderma.
Background: TEN is a severe form of exfoliative dermatitis. Its course is acute and its outcome fatal in 40% of cases. Wound cover to prevent fluid/protein loss and infections and to control pain, is the first step, as for burns.
