RATIONALE: Acral lentiginous melanoma (AML) does not exhibit the classic signs of malignant melanoma. ALM is frequently misdiagnosed because of its unusual sites and atypical clinical morphologies, which lead to poor prognosis. PATIENT CONCERNS: A female patient aged 78 years was presented to our center with two ulcers on her right foot. Diabetic foot ulcer was considered as the primary diagnosis. The ulcers failed to improve after 2 weeks' therapy. DIAGNOSES: An incisional biopsy of the lesion revealed malignant melanoma...

The aim of this study was to analyse the impact of socioeconomic status (SES) on the prognosis of patients with invasive malignant melanoma (MM) incident from 1991 to 2011 in the province of Ferrara, northern Italy. A total of 750 patients provided by the Area Vasta Emilia Centrale Cancer Registry were included in this retrospective cohort study. Prognosis was analysed in terms of overall survival and specific survival. The study determinants were the patients' SES and district of residence. The confounding effect of sex, age, period and TNM stage at diagnosis was evaluated...

Anti-melanoma differentiation-associated protein 5 (MDA5) antibody have been found in dermatomyositis (DM)-associated interstitial lung disease (DM-ILD) and DM-associated rapidly progressive ILD (DM-RPILD). Due to the conflicting results regarding the association between anti-MDA5 antibody and DM-ILD or DM-RPILD and the diagnostic value of this antibody for DM-ILD and DM-RPILD, we performed this meta-analysis. A systematic search was performed to identify studies published to January 14, 2017. Sixteen publications with 491 DM with ILD versus 605 DM without ILD, as well as eighteen publications with 186 DM with RPILD and 790 DM without RPILD were included...

PURPOSE: Brain metastases are a common problem in patients with melanoma, but little is known about the effect of gene mutations on survival in these patients. METHODS AND MATERIALS: We created a retrospective multi-institutional database of 823 patients with melanoma and brain metastases diagnosed between 2006 and 2015. Clinical parameters, gene mutation status (BRAF, C-KIT, NRAS), and treatment were correlated with survival. Treatment patterns and outcomes were compared with a prior era (1985-2005)...

Two types of immune checkpoint inhibitors, both antibodies that target cytotoxic T-lymphocyte antigen-4 and those that target programmed cell death-protein 1, have been approved for use in melanoma, non-small-cell lung cancer, and renal cell carcinoma as first-line or second-line therapy. Their adverse events are primarily regarded as immune-related adverse events. We felt it was important to pinpoint and discuss certain preconceptions or misconceptions regarding thyroid dysfunction, hypophysitis, and diabetes induced by immune checkpoint inhibitors...

A sentinel lymph node biopsy is a surgical staging procedure performed for patients with primary cutaneous melanoma who are clinically lymph-node negative to determine whether there is low volume nodal metastasis in the draining lymph node field. A systematic review was recently performed to update the Australian clinical practice guidelines for the diagnosis and management of melanoma, addressing the question, 'When is a sentinel lymph node biopsy indicated?' This article discusses the findings of the systematic review and the evidence base for the updated guidelines...

Werner syndrome (WS) is an autosomal recessive disease characterized by premature aging. Malignant tumors such as thyroid carcinoma and malignant melanoma occur frequently in WS patients. We describe 2 siblings with WS who suffered from sinonasal malignant melanoma (MM). Both patients initially experienced nasal obstruction and recurrent nasal bleeding and died within 2 years of the diagnosis of MM. Otolaryngologists should recognize that WS patients have a high risk for head and neck malignant disease, particularly sinonasal MM, even if they are aged below the expected age range and undergo periodic examinations...

The pathogenesis of melanomas emerging in plantar surfaces remains unclear; however, mechanical stress has been reported to increase the formation of melanomas. In this study, we conducted a multicenter retrospective analysis of 153 acral melanomas diagnosed between 2000 and 2015 in Taiwan. The male-to-female ratio of the patients in question was 1:1.28, and the mean age at diagnosis was 68 years. We examined whether melanomas which developed in different areas of the patients' soles differed in their associations with various clinicopathological characteristics and survival...

Hepatocellular carcinoma (HCC) is an aggressive cancer associated with high mortality worldwide. HCC develops in the setting of underlying cirrhosis due to chronic liver disease. Surgery is usually considered the treatment of choice for early disease; however, most patients have locally advanced or metastatic HCC at diagnosis in which case treatments are limited. Immune checkpoint blockade of programmed death receptor-1 (PD-1) pathway offers a potential treatment strategy based on the encouraging results of the phase I/II trial of nivolumab (Checkmate 040 trial)...

BACKGROUND: The tumor immune response is increasingly associated with better clinical outcomes in breast and other cancers. However, the evaluation of tumor-infiltrating lymphocytes (TILs) relies on histopathological measurements with limited accuracy and reproducibility. Here, we profiled DNA methylation markers to identify a methylation of TIL (MeTIL) signature that recapitulates TIL evaluations and their prognostic value for long-term outcomes in breast cancer (BC). METHODS: MeTIL signature scores were correlated with clinical endpoints reflecting overall or disease-free survival and a pathologic complete response to preoperative anthracycline therapy in 3 BC cohorts from the Jules Bordet Institute in Brussels and in other cancer types from The Cancer Genome Atlas...

INTRODUCTION: In most countries with a population of mainly European origin, non-melanoma skin carcinoma incidence rate has increased over the last decade. Understanding of what is the best way to identify people at high risk for skin cancer development will help to optimize the strategy for prevention and treatment tactics. Aim of the research involves studying risk factors for skin cancer development in patients with cutaneous squamous cell carcinoma and squamous cell carcinoma in situ (cSCC and SCCis correspondingly) and patients with actinic keratosis (AK)...

BACKGROUND: With the improving outcomes of patients with follicular lymphoma (FL), it is imperative to focus on survivorship issues, including the development of second primary malignancies (SPMs). We used a large US database to measure the risk of SPMs among FL survivors. MATERIALS AND METHODS: We used the Surveillance, Epidemiology, and End Results-13 registry to identify FL patients from 1992 to 2011. We calculated the risk of SPMs, developing ≥ 6 months after diagnosis, using the standardized incidence ratio (SIR) and absolute excess risk...

Leptomeningeal carcinomatosis is a rare but serious complication of solid tumors such as melanoma, breast and lung cancer, as well as gastrointestinal carcinomas. Its clinical manifestation is highly variable, presenting as radicular pain with or without neurological deficits, as well as with headaches and hallucinatory irritation symptoms. Leptomeningeal carcinomatosis is often misdiagnosed, which delays treatment. Here we report a rare case of a patient with BRAF-mutated microsatellite stable colon carcinoma with lymphatic and skeletal metastases, who developed neurological symptoms one month after the initial diagnosis of malignancy...

BACKGROUND: Acral lentiginous melanoma (ALM) is one of the four major subtypes in cutaneous melanoma (CM). Although ALM has a poorer prognosis than other CM subtypes, the prognostic factors of ALM have been verified only in small-sized cohorts because of the low incidence of ALM worldwide. OBJECTIVES: To investigate clinical characteristics of ALM and to evaluate their prognostic values based on a large dataset from the Central Malignant Melanoma Registry (CMMR) of the German Dermatologic Society...

BACKGROUND: There is no universally-accepted classification of spitzoid tumours. This makes difficult to assign a correct diagnosis and select a treatment that minimises the risk of overestimating, or worse, underestimating, the malignant potential of these tumours. To describe the clinical-pathological and epidemiological features of spitzoid tumours, as well as to assess mortality in these patients. METHODS: This retrospective cohort study looked at data on spitzoid tumours excised in 1999-2012 at the Dermatologic Clinic of the Turin University Hospital...

INTRODUCTION: Primary anorectal malignant melanoma is a rare and aggressive tumor that carries a poor prognosis. Anorectal melanoma (ARM) is often misdiagnosed as hemorrhoids adenocarcinoma polips and rectal cancer. ARM spreads along sub-mucosal planes and is often to wide-spread for complete resection at time of diagnosis and almost all patients die because of metastases.

BACKGROUND: Hispanics diagnosed with cutaneous melanoma are more likely to present at advanced stages but the reasons for this are unknown. We identify census tracts at high risk for late stage melanoma diagnosis (LSMD) and examine the contextual predictors of LSMD in California, Texas, and Florida. METHODS: We conducted a cross-sectional study using geocoded state cancer registry data. Using hierarchical multilevel logistic regression models we estimated ORs and 95% confidence intervals for the impact of socioeconomic, Hispanic ethnic concentration, index of dissimilarity, and health resource availability measures on LSMD...

Familial melanoma-astrocytoma syndrome is a tumor predisposition syndrome caused by inactivating germline alteration of the CDKN2A tumor suppressor gene on chromosome 9p21. While some families with germline CDKN2A mutations are prone to development of just melanomas, other families develop both melanomas, astrocytomas, and occasionally other nervous-system neoplasms including peripheral nerve sheath tumors and meningiomas. The histologic spectrum of the astrocytomas that arise as part of this syndrome is not well described, nor are the additional genetic alterations that drive these astrocytomas apart from the germline CDKN2A inactivation...
