UNLABELLED In sentinel node (SN) biopsy, an interval SN is defined as a lymph node or group of lymph nodes located between the primary melanoma and an anatomically well-defined lymph node group directly draining the skin. As shown in previous reports, these interval SNs seem to be at the same metastatic risk as are SNs in the usual, classic areas. This study aimed to review the incidence, lymph...

PURPOSE To screen the microarray expression of CDH1, ECM1, EIF1B, FXR1, HTR2B, ID2, LMCD1, LTA4H, MTUS1, RAB31, ROBO1, and SATB1 genes which are predictive of primary uveal melanoma metastasis, and NFKB2, PTPN18, MTSS1, GADD45B, SNCG, HHIP, IL12B, CDK4, RPLP0, RPS17, RPS12 genes that are differentially expressed in metastatic uveal melanoma in normal whole human blood and tissues prone to metas...

The distinction between primary melanoma and melanoma metastatic to the skin has major prognostic implications. We report a case of a 67-year-old male with a diagnosis of a superficial spreading melanoma (stage IB) rendered 6 years earlier who presented clinically with an atypical nevus on his left thigh. Histopathological examination showed an intraepidermal melanocytic proliferation that was ...

Uveal melanoma is the most common primary intraocular malignant tumor in adults and half of the primary tumors will develop fatal metastatic disease to the liver and the lung. Crizotinib, an inhibitor of c-Met, anaplastic lymphoma kinase (ALK), and ROS1, inhibited the phosphorylation of the c-Met receptor but not of ALK or ROS1 in uveal melanoma cells and tumor tissue. Consequently, migration o...

Primary malignant melanoma of the oral cavity is a rare malignancy with an incidence 0.2 to 8% all melanomas. Melanoma arises from transformation melanocyte and cutaneous melanomas are most common followed by ocular, mucosal unknown primary site. Here we present case 54 year old male who presented pigmented lesion on palate, type melanoma. Due rarity this disease, it infrequently studied. Hence...

Although gastrointestinal involvement by metastatic malignant melanoma is common but primary gastrointestinal (GI) melanoma has been reported in rare cases. In this study we report two cases of primary gastrointestinal malignant melanoma that one of them is a known case of neurofibromatosis type 1(NF1). Both cases showed no evidence of any lesions in skin and eye. Malignant melanoma of GI tract...

Although malignant melanoma usually occurs after the diagnosis of vitiligo-like depigmentation, the latter is rarely followed by the former. We herein report on such a case in which recognition of the vitiligo-like depigmentation preceded diagnosing the metastatic melanoma by several months. A 56-year-old woman had first developed vitiligo-like depigmentation on the forehead, eyelids, neck and ...

Metastatic melanoma, the primary cause of skin cancer-related death, warrants new therapeutic approaches that target the regulatory machinery at molecular level. While long noncoding RNAs (lncRNAs) are dysregulated in a number of cancer types, limited data are available on the expression and function of lncRNAs in melanoma metastasis. The primary objective of this study was to investigate the r...

Metastatic uveal melanoma to the contralateral orbit is extremely rare, with only eight cases in the literature having been reported. We reviewed the clinical presentation, the histologic findings of the primary and secondary tumors, and the clinical outcome of these cases and studied an additional case of metastatic choroidal melanoma to the contralateral orbit that occurred 40 years after enu...
