Metastatic malignant melanoma is the most lethal cutaneous neoplasm, originating from melanocytes and characterized by aggressive behavior and distant dissemination via lymphatic and hematogenous routes. Risk factors include phenotypic traits, genetic mutations, and environmental exposures. Histologically, it presents with atypical melanocytes invading the dermis, often showing nuclear pleomorphism, mitoses, and ulceration. Breslow thickness is the key prognostic indicator. Management is multidisciplinary, with surgical resection as first-line when feasible. In unresectable cases, treatment is guided by molecular profiling. We present the case of a 81-year-old female with rapid progression of the disease and ganglionar metastases.
