Metastatic malignant melanoma of the urinary bladder is a rare clinical finding suggestive of advanced disease. Only 17 cases have been described in the English literature. We present a case of an 84-year-old male who was referred to the urology department with the incidental finding of bladder metastases on computed tomography (CT) one year following the diagnosis of malignant melanoma of the ...

Clear cell sarcoma of soft tissue is a rare type of soft tissue sarcoma. It is derived from melanoblast-like cells located within subcutaneous tissue, tendon and aponeuroses. The tumour is also known as malignant melanoma of soft parts because it has similar morphology to malignant melanoma. Unlike malignant melanoma, however, it is not associated with a cutaneous lesion. We report here two cas...

DNA-damaging anticancer drugs remain a part of metastatic melanoma therapy. Epigenetic reprogramming caused by increased histone deacetylase (HDAC) activity arising during tumor formation may contribute to resistance of melanomas to the alkylating drugs temozolomide, dacarbazine, and fotemustine. Here, we report on the impact of class I HDACs on the response of malignant melanoma cells treated ...

background: malignant melanoma is a highly aggressive malignant melanocytic neoplasm which resists against the most conventional therapies. sea cucumber as one of marine organisms contains bioactive compounds such as polysaccharide, terpenoid and other metabolites which have anti-cancer, anti-tumor, anti-inflammatory and antioxidant properties. the present study was designed to investigate the ...

Cutaneous malignant melanoma represents the major cause of mortality among skin cancers. Metastasis-associated protein CD24 is a small, heavily glycosylated cell surface protein that is overexpressed in various human malignancies. The present study was designed to determine the roles of CD24 in cutaneous malignant melanoma. The levels of CD24 mRNA and protein in cutaneous malignant melanoma tis...

Aims. Metastatic malignant melanoma of the urinary bladder is a rare clinical entity, with only twenty-three published cases to date. We present a case of this rare entity, a thorough review of the literature, and differential diagnosis of melanoma in the bladder. Methods and Results. A 55-year-old woman with a history of malignant melanoma of the right thigh, excised eight years ago, presented...

Malignant melanoma is one of the few malignancies that are well known for unusual behavior. Primary malignant melanoma usually originates from squamous epithelium of skin, mucous membranes, retina, and uvea. Although melanoma can metastasize to any part of the body, including biliary tract, primary malignant melanoma of bile ducts is an extremely rare entity. We present a 52-year-old man who pr...

Fig 1. Left side of the chest skin biopsy for primary malignant melanoma. Histopathologic examination found a thick primary melanoma characterized by atypical pigmented epithelioid cells with extensive ulceration. INTRODUCTION Spontaneous regression of malignant melanoma is defined by the disappearance of melanocytic neoplastic cells partially or completely. In contrast to the partial form, com...
