Metastasis
Malignant melanoma is an exceptionally large capacity for metastasis through blood and lymph vessels. They are divided into so-called. local and distant metastases. Among the distinguished local metastatic satellite metastases (in the immediate vicinity of the tumor), transit (located in the course of lymphatic vessels) and metastasis to lymph nodes located near the tumor. Distant metastases can be located such in the lungs, liver, bone, brain. First metastases may unfortunately appear immediately in the internal organs.
The course of melanoma is the most chronic and progressive. Summit metastasis usually occurs after the first and second year after diagnosis, although some are late and metastasis (5-10 years after diagnosis). There are also cases of spontaneous regression of histologically proven metastases.
