Anorectal malignant melanoma is a very rare but lethal disease. Patients with anorectal malignant melanoma commonly complain for changes in bowel habits and rectal bleeding. Therefore, anorectal malignant melanoma is often misdiagnosed as hemorrhoids, polyp or rectal cancer. Surgery is the mainstay of treatment for patients with anorectal malignant melanoma. However, whether abdominoperineal re...

BACKGROUND Epidemiological studies evaluating the association between sunscreens use and malignant melanoma risk have produced inconsistent results. Thus, we conducted a meta-analysis to summarize the evidence from epidemiological studies of sunscreens use with the risk of malignant melanoma. METHODS Pertinent studies were identified by a search in PubMed and Web of Knowledge up to October 20...

Careful study of capillary endothelial cells as part of the stroma reaction in human malignant melanoma showed branched tubular structures (BTS). These structures were found in five cases, two of which were melanoma superficial spreading type with strong host cellular response (level 2 invasion), and one of which was a nodular melanoma (level 3 invasion) associated with a good host-cellular TAB...

-Tumour antigen-induced inhibition of leucocyte adherence was modified for use in glass test tubes (Tube LAI assay) for the study of cell-mediated antitumour immunity to human malignant melanoma. Peripheral blood leucocytes (PBL) of 20 out of 25 patients (80%) with active malignant melanoma responded to an extract of malignant melanoma with LAI, whereas only 4.5%o of 475 control subjects showed...

background: malignant melanoma is a highly metastatic cutaneous cancer and typically refractory to chemotherapy. deregulated apoptosis has been identified as a major cause of cancer drug resistance, and upregulated expression of the inhibitor of apoptosis protein melanom, an inhibitor of apoptosis (ml-iap) is frequent in melanoma. methods: based on the conclusion that ml-iap expression contribu...

oral malignant melanoma (omm) accounts for 5% of all oral malignancies. it is a rare aggressive neoplasm usually found on the hard palate and gingiva. the etiology is unknown, but tobacco and chronic irritation are suggested as probable causative factors. over 30% of the cases have been reported to arise from pre-existing pigmented lesions. a biopsy is required to establish the diagnosis and th...

Malignant melanoma arises by malignant transformation of the normal melanocytes. Distribution of malignant melanoma includes cutaneous (91.2%), ocular (5.3%), mucosal (1.3%), and unknown primary site (2.2%) [1]. Because of rarity and clinical challenges arising from different anatomic location, our understanding for the optimal management of mucosal melanoma remains limited. Malignant melanoma ...

Dysregulated microRNA (miR)-625 expression has been observed in several kinds of cancer. MicroRNAs are important factors in the development and progression of malignant melanoma, though the clinical significance and function of miR-625 in human malignant melanoma remain unclear. Levels of miR-625 expression were therefore determined in 36 pairs of malignant melanoma and adjacent non-tumor tissu...

Primary malignant melanoma of uterine cervix is extremely rare malignancy with very few case published reports. This neoplasm is having poor prognosis, so early diagnosis, staging and treatment is of extreme importance. 18F-FDG PET-CT (18F-labeled fluoro-2-deoxyglucose positron emission computed tomography) scan is an established modality to determine exact extent of disea...
