Background and Aim: Malignant melanoma is one of the most dangerous types of skin cancer. The aim of this study was to evaluate Spatial Thermographic Imaging (STI) in differentiating benign from malignant skin lesions. Methods: One-hundred and ten STI images were taken from the volunteers who had lesions being suspected for malignant melanoma. Benignity or malignancy of lesions was determine...
Malignant melanoma in children is rare. It can arise from congenital melanocytic nevi. In pediatric patients, diagnosis of melanoma is difficult and challenging because the physicians have a low index of suspicion. Marrow metastasis in malignant melanoma especially in children is extremely uncommon. Here, the authors reported a 5 year old girl who was presented with a 4 month history of pelvic ...
Herein we describe a case of intraocular melanoma in a17-year old leukemic patient. The history, histological findings of the enucleated eye, blood and bone marrow of the patient were investigated. The enucleated eye contained epitheloid cell type melanoma instead of leukemic cell infiltration. We conclude that intraocular malignant melanoma can occur in acute lymphoblastic leukemia.
Acral lentiginous melanoma (ALM) is the most common type of cutaneous melanoma which can occur on the palms, soles or beneath the nail plate. Diagnosis of ALM is usually delayed and melanomas can only be diagnosed at advanced clinical stage so the prognosis is often poor. We report a case of Acral lentiginous melanoma which misdiagnosed as chronic ulcer. Chronic lesions even if benign i...
melanoma of the oral cavity is a rare malignant disease. on account of the presence at relatively obscure areas in the oral cavity, most of oral malignant melanomas are diagnosed at a late stage. early diagnosis is essential for successful treatment and perhaps is the key factor in improving the prognosis of oral malignant melanoma. however, no large clinical series exist, and in fact, clinical...
Melanoma is a malignant tumor that originates from melanocyte cells. Its oral type is rare. The goal of this investigation was to determine the prevalence of oral malignant melanoma in Iran, as determined by age, sex and location. This research reviewed 623 cases of oral and non-oral malignant melanoma in Immam-Khomeini hospital, Mearaj cancer institute and department of oral pathology of denta...

Background: Melanoma is a neoplasm derived commonly from melanocytic cells of skin. Although coetaneous presentation of malignant melanoma is easily recognizable, the presentation of melanoma in other organs is so confusing. In particular, when it metastasizes to other organs, many bizarre figures and unusual organs may be involved. In this report, we present a case of primary duodenal malignan...
cancer is the second important reason of mortality in the world. in this regard melanoma was accounted as the most aggressive type of coetaneous cancer. among drug extracted from natural products from marine organisms have been focused investigations related to chemotherapeutic agents derived from echinoderms such as sea cucumbers and starfish. in the present study, cytotoxic and apoptosis ind...
Objective(s): Growing evidences have indicated microRNAs as modulators of tumor development and aggression. On the other hand, a phenomenon known as epithelial-mesenchymal transition (EMT) that indicates a transient phase from epithelial-like features to mesenchymal phenotype is a key player in tumor progression. In this study, we aimed to assess the potential impacts...
