A rare case of intracranial metastatic amelanotic melanoma with cyst is presented. The patient was a 51 year old woman with a malignant melanoma arising on her right chest. Two years after a wide excision, skin and brain metastasis occurred. Brain magnetic resonance images demonstrated a tumour with a cyst in the left occipital lobe. Because the tumour showed low intensity on T1 weighted images...

IMPORTANCE Conventional melanoma serum biomarkers (S100 and lactate dehydrogenase [LDH]) perform poorly in patients with uveal melanoma, and the search for new biomarkers is needed. A high expression of the oncoprotein c-Met in primary uveal melanoma is associated with metastatic progression, and c-Met is released as a soluble ectodomain through ADAM10- and ADAM17-mediated cleavage, suggesting ...
INTRODUCTION Compared with other tumors, melanoma has displayed one of the largest increases in incidence in recent years, and it is known to have a high metastatic potential. In cases of metastasis, approximately two-thirds of patients have lymph-node metastases and one-third develop systemic metastases. However, few studies have been reported that analyzed different metastatic patterns accord...
We report a young male with an initial excisional biopsy report of melanoma of the lower back, referred to our hospital for complete excision and sentinel lymph node (SLN) biopsy. Four peritumoral intradermal Tc-99m phytate injection was performed and SLNs were detected in both axillary and right inguinal regions. On the biopsy only the right axillary SLN was metastatic leading to right axilla...
BACKGROUND Enhancer of zeste homolog 2 (EZH2), a polycomb group protein that regulates the cell cycle, has recently been implicated in the progression of several human cancers. We sought to determine the pattern of EZH2 expression in benign and malignant melanocytic tumors to see if EZH2 might play a role in melanoma pathogenesis and progression. METHODS We identified and reviewed 11 compound...
PURPOSE Both phosphatidylinositol 3-kinase/AKT and RAS/mitogen-activated protein kinase signal transduction pathways mediate 4E-BP1 phosphorylation, releasing 4E-BP1 from the mRNA cap and permitting translation initiation. Given the prevalence of PTEN and BRAF mutations in melanoma, we first examined translation initiation, as measured by phosphorylated 4E-BP1 (p-4E-BP1), in metastatic melanoma...
There has been a steady rise in fatalities associated with thick melanomas (>4mm). Although understanding of the biology of the disease has improved, effective treatment strategies for patients with advanced metastatic melanoma remain elusive. Therefore, more intensive testing of agents with therapeutic potential are needed to improve survival of patients with metastatic malignant melanoma. We ...
