متن کاملCongenital giant melanocytic nevi
Nevi are common skin tumors caused by abnormal overgrowth of cells from the epidermal and dermal layers of the skin. Most nevi are benign, but some pre-cancerous nevi must be monitored or removed. The giant congenital nevus is greater than 10 cm in size, pigmented and often hairy. Between 4% and 6% of these lesions will develop into a malignant melanoma. Since approximately 50% of the melanoma ...
متن کاملAllelotypes of primary cutaneous melanoma and benign melanocytic nevi.
A multistep genetic model of tumorigenesis, based on genetic alterations in benign and primary malignant lesions, has been proposed for neoplasms such as colonic carcinoma. However, evidence for a similar genetic progression in melanoma has relied heavily on findings in cultured lesions or metastases. We have investigated every autosomal arm for loss of heterozygosity in 41 primary cutaneous me...
متن کاملA comparative study of estrogen receptor beta expression in melanoma and benign melanocytic lesions
Background: Malignant melanoma is the most aggressive form of skin cancer. In contrast to other tumors, the role of estrogen in the initiation and progression of melanoma remains unclear. The aim of this study was to evaluate estrogen receptor beta protein expression in human melanoma tissues and in the benign melanocytic lesions. Method: Twenty-one patients, 11 with cutaneous melanoma and 10 w...
متن کامل[Melanocytic nevi, melanoma, and pregnancy].
Malignant melanoma is among the malignant tumors whose incidence has risen markedly in recent decades. For many years the medical community debated the potential adverse effects of female hormones (whether of exogenous or pregnancy-related endogenous origin), on melanocytic nevi and malignant melanoma. Given that women have been delaying pregnancy until their thirties or forties and that the in...
