[Metastatic melanoma of the brain].

Clinical and clinico-pathoanatomical comparisons (60 observations) have shown that in patients with primary cutaneous melanoma and its metastases treated by modern methods the tumour metastasis to the brain occurs in late periods of the disease at the stage of the neoplastic process generalization. Histological examinations of the melanoma metastases of various localization revealed a much lesser differentiation of the tumour cells and a greater vascularization of the tumour. The pronounced vascularization is characteristic for metastases of any localization, both visceral and cerebral, at the stage of the process generalization.
