Primary melanoma in the central nervous system is very rare, currently little domestic coverage, now our hospital encountered two cases of primary melanoma in the brain and bone marrow are reported as follows: Example 1, male, 32 years old, due to low back pain With bilateral lower extremity progressive weakness, dyskinesia 4 months, on December 24, 1984 admission. Physical examination: No melanoma was found in the skin and mucous membranes. No abnormalities were found in the cranial nerves. The left lower extremity muscle strength was grade Ⅳ, the right lower extremity muscle strength was grade Ⅱ, the lower extremity muscle tension was decreased, the tendon reflex disappeared, the left cremasteric reflex was weakened and the right disappeared.

Clinical diagnosis of spinal cord compression. On January 10, 1985 under local anesthesia to T_ (12) -L_1 center for spinal exploration, see T_ (10) -L_1 intraoperative epidural
