Malignant melanoma is an aggressive cutaneous melanocytic neoplasia of fast spread1. Despite its diagnosis, the disease mortality still reaches high levels. Metastasis to the oral cavity of the cutaneous melanoma is rare2-5: until 2001 less than 30 cases of metastasis in the palatine tonsils had been published3. This type of dissemination is blood-born and the prognosis is deleterious. The reas...

Multiple metastases often differ in biologic characteristics and can change during the course of the disease. Clonal analysis of human melanoma suggest that systemic, physiologic signals can be recognized by neoplas...
متن کاملDecoding Melanoma Metastasis
Metastasis accounts for the vast majority of morbidity and mortality associated with melanoma. Evidence suggests melanoma has a predilection for metastasis to particular organs. Experimental analyses have begun to shed light on the mechanisms regulating melanoma metastasis and organ specificity, but these analyses are complicated by observations of metastatic dormancy and dissemination of melan...
