AIMS: Diagnosis of undifferentiated pleomorphic sarcoma (UPS) may be challenging, as other lesions with undifferentiated spindle cell morphology must be excluded, including melanoma. Microphthalmia-associated transcription factor (MiTF) stains nevi and epithelioid melanomas, as well as some mesenchymal neoplasms. We evaluated the prevalence of MiTF and melanocytic markers in UPS and a subset of atypical fibroxanthoma (AFX). METHODS AND RESULTS: MiTF, SOX10, Melan-A, HMB45, and S100 immunostains were performed on resection specimens from 19 UPS and 5 AFX...

Oral cavity mucosal melanomas (OCMM) represent only 3% of all malignant melanomas. Surgery is the mainstay of treatments and it is often followed by adjuvant radiotherapy. The role of adjuvant immunotherapy and/or chemotherapy is still debated and to date neither treatment is routinely used. From January 1990 to January 2010, we have collected from our database data of 20 patients with a histologically proven diagnosis of OCMM. Upfront surgery, followed by adjuvant radiotherapy was performed in 16/20 (80%) patients...

Over 20% of cancer patients will develop brain metastases. Prognosis is currently extremely poor, largely owing to late-stage diagnosis. We hypothesized that biofluid metabolomics could detect tumours at the micrometastatic stage, prior to the current clinical gold-standard of blood-brain barrier breakdown. Metastatic mammary carcinoma cells (4T1-GFP) were injected into BALB/c mice via intracerebral, intracardiac or intravenous routes to induce differing cerebral and systemic tumour burdens. B16F10 melanoma and MDA231BR-GFP human breast carcinoma cells were used for additional modelling...

In transit metastases (ITM) from extremity or trunk melanomas are subcutaneous or cutaneous lymphatic deposits of melanoma cells, distant from the primary site but not reaching the draining nodal basin. Superficial ITM metastases develop in 5-10% of melanoma patients and are thought to be caused by cells spreading along lymphatics; ITM appear biologically different from distant cutaneous metastases, these probably due to a haematogenous dissemination. The diagnosis is usually clinical and by patients, but patients need to be adequately educated in the recognition of this clinical situation...

BACKGROUND/AIM: Many patients with brain metastases from melanoma receive whole-brain radiotherapy (WBRT). WBRT-regimens must consider the patient's prognosis in order to deliver the best therapy. PATIENTS AND METHODS: Seven factors were correlated to intracerebral control and survival after WBRT alone in 92 patients with melanoma: WBRT regimen, age at WBRT, gender, Karnofsky performance score (KPS), number of brain lesions, number of extracranial metastatic sites, and time from melanoma diagnosis to WBRT...

OBJECTIVE: Anti-MDA5 antibody positive dermatomyositis (DM) and clinically amyopathic DM (CADM) often develop into rapidly progressive interstitial lung disease, but their pathogenesis remains unclear. We observed that sera from DM/CADM patients immunoprecipitated a common 110 kDa polypeptide. We investigated this autoantigen and its clinical significance. METHODS: Autoantibodies were screened in 333 patients with various connective tissue diseases (CTDs) and 20 healthy controls (HCs) by immunoprecipitation with [(35)S]methionine-labeled HeLa cells...

BACKGROUND: Over the past two decades, there has been a rising trend in malignant melanoma incidence worldwide. In 2008, Germany introduced a nationwide skin cancer screening program starting at age 35. The aims of this study were to analyse the distribution of malignant melanoma tumour stages over time, as well as demographic and regional differences in stage distribution and survival of melanoma patients. METHODS: Pooled data from 61 895 malignant melanoma patients diagnosed between 2002 and 2011 and documented in 28 German population-based and hospital-based clinical cancer registries were analysed using descriptive methods, joinpoint regression, logistic regression and relative survival...

Carcinomatous lymphangitis accounts for 5% of all skin metastases, but blue lymphangitis of the breast has never been described. We report a case of blue lymphangitis of the breast in a patient 11 years after treatment for ipsilateral breast cancer that was in full remission. Breast examination and imaging showed no other abnormalities. Skin biopsy revealed a carcinomatous-pigmented infiltration corresponding to melanoma metastasis, which helped highlight a primitive right flank injury. This case report emphasizes that a full body exam should always be performed with unusual presentation of breast cancer and reiterates the indispensable place of histology before any diagnosis...

BACKGROUND: BRAF(V600) , NRAS, TP53, and BRAF(Non-V600) are among the most common mutations detected in non-acral cutaneous melanoma patients. Although several studies have identified clinical and pathological features associated with BRAF(V600) and NRAS mutations, limited data are available regarding the correlates and significance of TP53 and BRAF(Non-V600) mutations. METHODS: This study analyzed the patient demographics, primary tumor features, and clinical outcomes of a large cohort of non-acral cutaneous melanoma patients who had undergone clinically indicated molecular testing (n = 926)...

REVIEW
S Kaliki, C L Shields
Although it is a relatively rare disease, primarily found in the Caucasian population, uveal melanoma is the most common primary intraocular tumor in adults with a mean age-adjusted incidence of 5.1 cases per million per year. Tumors are located either in iris (4%), ciliary body (6%), or choroid (90%). The host susceptibility factors for uveal melanoma include fair skin, light eye color, inability to tan, ocular or oculodermal melanocytosis, cutaneous or iris or choroidal nevus, and BRCA1-associated protein 1 mutation...

INTRODUCTION: The incidence of cutaneous melanoma is increasing in Denmark and worldwide. However, the prevalence of distant metastases at the time of diagnosis has decreased to 1%. We therefore questioned the value of routine preoperative chest X-ray (CXR) for staging asymptomatic melanoma patients and hypothesised that routine CXR is not justified. METHODS: A retrospective study was conducted on patients undergoing wide local excision and sentinel lymph node biopsy for cutaneous melanoma in the period from 2010 to 2014...

BACKGROUND: When encountering solid pancreatic lesions, nonpancreatic primary metastases are rare and differentiating a metastasis from a primary neoplastic lesion is challenging. The clinical presentation and radiologic features can be similar and the possibility of a pancreatic metastasis should be considered when the patient refers to a history of a different primary cancer. Endoscopic ultrasound offers a key anatomical advantage in accessing the pancreas and endoscopic ultrasound-guided fine-needle aspiration has become the gold standard method for diagnosing pancreatic lesions...

Understanding the events at a protein level that govern the progression from melanoma in situ to invasive melanoma are important areas of current research to be developed. Recent advances in the analysis of formalin-fixed, paraffin-embedded tissue by proteomics, particularly using the filter-aided sample preparation protocol, has opened up the possibility of studying vast archives of clinical material and associated medical records. In the present study, quantitative protein profiling was performed using tandem mass spectrometry, and the proteome differences between melanoma in situ and invasive melanoma were compared...

Background Diagnostic confirmation of spindle-cell melanoma (SM) or desmoplastic melanoma (DM) as a melanoma can be challenging. In conventional melanoma (CM), a recently established fluorescence in situ hybridization (FISH) assay for RREB1, MYB, CCND1 can be helpful. Here, we determined the presence of RREB1, MYB, and CCND1 abnormalities in an SM/DM/mixed cohort. Methods We assembled 49 cases and performed 3 separate hybridizations for RREB1/MYB/CCND1 We assessed clinical utility in diagnostically challenging cases and performed a cost and turnaround time analysis...

Carcinoma of unknown primary is a type of malignant disease where the primary carcinoma cannot be identified by conventional examination, which presents challenges in diagnosis and therapy. This study aims to evaluate the detailed clinical value and indications of using fluorine-18-2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (F-18 FDG PET/CT) in a large sample. A total of 449 patients who were selected under strict standards were retrospectively included in this study. F-18 FDG PET/CT accurately detected the primary carcinoma in 115 of 449 patients whose primaries could not be detected by conventional examination (25...
