BACKGROUND: Immunotherapy plays a key role in the treatment of metastatic melanoma. Patients with autoimmune conditions and/or on immunosuppressive therapy due to orthotropic transplants, however, are systematically excluded from clinical trials. Talimogene laherparepvec (T-VEC) is the first oncolytic virus to be approved by the FDA for cancer therapy. To our knowledge, this is the first report of T-VEC being administered in the setting of an organ transplant recipient. CASE PRESENTATION: Here we present the case of a patient with recurrent locally advanced cutaneous melanoma receiving salvage T-VEC therapy in the setting of orthotropic heart transplantation...

Patients suffering from Epidermodysplasia verruciformis (EV), a rare inherited skin disease, display a particular susceptibility to persistent infection with cutaneous genus beta-human papillomavirus (beta-HPV), such as HPV type 8. They have a high risk to develop non-melanoma skin cancer at sun-exposed sites. In various models evidence is emerging that cutaneous HPV E6 proteins disturb epidermal homeostasis and support carcinogenesis, however, the underlying mechanisms are not fully understood as yet. In this study we demonstrate that microRNA-203 (miR-203), a key regulator of epidermal proliferation and differentiation, is strongly down-regulated in HPV8-positive EV-lesions...

Uveal melanomas (UMs) are a rare form of cancer with clinical and pathological characteristics distinct from cutaneous melanomas. Ipilimumab has shown efficacy and safety in the treatment of metastatic UM. This provides a rationale for treatment with other immune checkpoint inhibitors. This is a retrospective review of 15 patients with metastatic UM treated between June 2014 and February 2016, who received treatment with the anti-PD-1 Abs pembrolizumab or nivolumab. Patients were treated at two German university hospitals...

Cutaneous T-Cell Lymphomas (CTCL) are rare, but potentially devastating malignancies, whose pathogenesis remains poorly elucidated. Unfortunately, currently it is not possible to predict based on the available criteria in which patients the cancer will progress and which patients will experience an indolent disease course. Furthermore, at early stages this malignancy often masquerades as psoriasis, chronic eczema or other benign inflammatory dermatoses. As a result, it takes on average 6 y to diagnose this lymphoma since its initial presentation...

INTRODUCTION: The incidence and mortality rates of cutaneous melanoma (CM) are increasing among fair-skinned populations worldwide. Ultraviolet radiation (UVR) is the principal risk factor for CM, but is also the main source of 25-hydroxyvitamin D (25(OH)D), which has been associated with reduced risk and better prognosis of some cancer types. However, both low and high 25(OH)D levels have been associated with increased risk of CM. Obesity as measured by body mass index (BMI) is associated with risk of several cancers and has also been suggested as a risk factor for CM, and may also be related to insufficient 25(OH)D and/or high leptin levels...

BACKGROUND: Neurofibromatosis type 1 (NF1: Online Mendelian Inheritance in Man (OMIM) #162200) is an autosomal dominantly inherited tumour predisposition syndrome. Heritable constitutional mutations in the NF1 gene result in dysregulation of the RAS/MAPK pathway and are causative of NF1. The major known function of the NF1 gene product neurofibromin is to downregulate RAS. NF1 exhibits variable clinical expression and is characterized by benign cutaneous lesions including neurofibromas and café-au-lait macules, as well as a predisposition to various types of malignancy, such as breast cancer and leukaemia...

Cutaneous melanoma is the most aggressive form of skin cancer. This aggressiveness appears to be due to the cancer cells' ability to reversibly switch between phenotypes with non-invasive and invasive potentials, and microphthalmia-associated transcription factor (MITF) is known to play a central role in this process. The transcription factor glioma-associated oncogene homolog 1 (GLI1) is a component of the canonical and noncanonical sonic hedgehog pathways. Although GLI1 has been suggested to be involved in melanoma progression, its precise role and the mechanism underlying invasion remain unclear...

In most cases, cutaneous metastases develop after the diagnosis of the primary internal malignancy has been established, but sometimes they can be discovered earlier or simultaneously. We describe a case of a 90-year-old woman who presented to the emergency room in poor general condition, with cutaneous lesions characterized by hot, infiltrated, violaceous and erythematous plaques involving the left chest wall. The clinical and histopathological findings were consistent with the recently described variant of inflammatory cutaneous metastatic carcinoma named carcinoma hemorrhagiectoides...

Primary cutaneous angiosarcoma is a rare vascular tumor usually affecting the whole body, and its hypermetabolic features on F-FDG PET/CT may be confused with those of infection, metastasis, or primary malignancy. This is a case report of a cutaneous angiosarcoma of the lower anterior abdomen showing increased FDG uptake on F-FDG PET/CT mimicking a cutaneous metastasis in an 84-year-old woman with cervical cancer.

A cutaneous horn could be defined as a conical projection on the surface of skin made of cornified material and resembling an animal horn. These lesions most commonly affect light-skinned men aged between 50 to 89 years and usually appear in sun exposed areas. Radiation, chronic irritation and even human papilloma virus-2 infection may be precipitating factors. More than half of the cases originate from either malignant or premalignant lesions, therefore the base of the lesion must be carefully examined histologically...

Primary cutaneous large B-cell lymphoma (Bcl) is defined as a lymphoma composed of large cells constituting more than 80% of the infiltrate and absence of extracutaneous involvement after staging investigations. In the new World Health Organization/European Organization for Research and Treatment of Cancer classification, cutaneous Bcls with large cells are of three types - primary cutaneous large Bcl leg type (PCLBCLLT), primary cutaneous follicle center lymphoma diffuse type (PCFCLDT), and primary cutaneous large Bcls other (PCLBCLO)...

Laboratory studies show lithium, an activator of the Wnt/ß-catenin signaling pathway, slows melanoma progression, but no published epidemiologic studies have explored this association. We conducted a retrospective cohort study of adult white Kaiser Permanente Northern California members (n=2,213,848) from 1997-2012 to examine the association between lithium use and melanoma risk. Lithium exposure (n=11,317) was assessed from pharmacy databases, serum lithium levels were obtained from electronic laboratory databases, and incident cutaneous melanomas (n= 14,056) were identified from an established cancer registry...

<p>The Food and Drug Administration approved Ruxolitinib in 2011 for the treatment of primary myelofibrosis. Five-year safety data showed a higher incidence of skin cancer in patients treated with Ruxolitinib compared to best available therapy for myelofibrosis. This report presents a series of five patients with history of myelofibrosis treated with Ruxolitinib who subsequently developed numerous skin cancers with aggressive biological behavior. Each patient in this report was treated by a Mohs surgeon affiliated with an academic institution...

The oligometastatic melanoma is a peculiar stage of cancer progression which is initially restricted to the initial body area. In most instances, only a small number of metastases are simultaneously present. The oligometastatic stage is synchronous when metastases are disclosed at the time of initial diagnosis of the primary cancer. Metastases are metachronous when they are detected after the initial treatment of the primary neoplasm. A variant of the disease is called the smouldering disease when cutaneous metastases grow or regress in unison...

ETHNOPHARMACOLOGICAL RELEVANCE: 8-methoxypsoralen (8-MOP) is a furanocoumarin and an active compound of a traditional Egyptian medicinal plant Ammi majus L, whose juice/fruit has been used for many years in folk phototherapy for the treatment of vitiligo or a hyperproliferative skin disorder, psoriasis. 8-MOP together with UVA light is also used as an anticancer drug for the treatment of cutaneous T-cell lymphoma. However, furanocoumarins exert anticancer activity even without UV irradiation...
