primary [1] and metastatic intestinal melanoma, as previously described [2] and illustrated with surgical and histolo− gical verification [3]. However, capsule enteroscopic identification of the charac− teristic coal−black appearance of malig− nant melanoma has not been described previously in intestinal tumors. A 56−year−old man receiving dendritic cell−based therapy for metastatic malig− nant...
Immunohistochemical analysis has consistently shown that cyclin E is up-regulated in human malignant melanomas in vivo. Here we analyzed such expression in more detail and show that cyclin E is overexpressed and present in low molecular weight (LMW) isoforms in metastatic melanoma and in a subset of primary invasive melanoma tumor tissues, but not in benign nevi. Human metastatic melanoma cell ...
OBJECTIVE To determine if patients diagnosed as having metastatic uveal melanoma before the onset of symptoms experience more favorable survival outcomes than patients diagnosed after the onset of symptoms. METHODS A retrospective cohort study was performed among 90 patients who were diagnosed as having metastatic uveal melanoma after proton beam irradiation by routine surveillance testing (a...
INTRODUCTION Benzamide can specifically bind to melanoma cells. A 18F-labeled benzamide derivative, [18F]N-(2-diethylaminoethyl)-4-[2-(2-(2-fluoroethoxy) ethoxy)ethoxy]benzamide ([18F]FPBZA), was developed as a promising PET probe for primary and metastatic melanoma. METHODS [18F]FPBZA was synthesized via a one-step radiofluorination in this study. The specific uptake of [18F]FPBZA was studie...
Melanoma is originating from melanocytes, it a malignant tumor with high metastatic potential. It the leading cause of moratlity skin cancer, Nail melanoma rare form melanoma. we report new case this localization
Advances in the treatment of melanoma are resulting in patients living for extended periods after being diagnosed with metastatic disease. Metastases to the ureter are rare, but they have been described in the literature on a number of occasions. In this case report, we describe a patient with established metastatic melanoma who, whilst taking and responding to immunomodulatory therapy, was fou...
To date there is no effective therapy for metastatic melanoma and at the molecular level the disease progression is poorly understood. A recent study by our group led to the development of a novel phenotype switching model for melanoma progression, wherein cells transition back-and-forth between states of proliferation and invasion to drive disease progression. To explore the model's clinical r...
Breast skin and parenchyma are metastatic sites for various tumours. Metastasis to the breast is rare, but it must be considered in the differential diagnosis of a breast mass. Melanoma is among the most commonly reported metastatic tumours of the breast. With the increasing incidence of melanoma, this complication is being encountered with greater frequency. Melanoma has different manifestatio...
Malignant melanoma is the most aggressive type of skin cancer. RAB22A, a member of RAS oncogene family, has been found to be significantly upregulated in multiple human cancers. In the present study, we found that RAB22A mRNA expression was significantly upregulated in melanoma tissues (including 60 primary melanomas and 84 metastatic melanomas) compared to benign nevi (n = 20), which were sign...
Fusion of Cloudman S91 melanoma cells with macrophages results in hybrids with increased metastatic potential. Here, we report that such hybrids acquire new pathways for motility. Compared to parental melanoma cells and low metastatic hybrids, the metastatic hybrids showed far stronger responses to 3T3- and lung fibroblast-conditioned media, primary lung slices, fibronectin (FN), and a Mr 120,0...
