抄録

A sixty-three years old man have complained the low back pain with the radiation pain to the right thigh since January 1968. He admitted to our hospital with the limitation of extension of the right hip due to the pain in February 1968.
After two weeks of hospitalization, he had dysuria motor loss of both legs and saddle block sensory disturbance. The spinal tumor was suspected and the blockage below the third lumbar vertebra was demonstrated on myelogram. On march 21, 1968, the operation was performed. The tumor was placed in extradural space (L3-L5) and removed.
Microscopic examination revealed the reticulum cell sarcoma. The patient's postoperative course was becoming worse and died forty days after operation. At autopsy same tumor in the origin of right Psoas Major Muscle from 4th lumbar vertebral body to the 5th was found. But the tumor was not demonstrated in the lymphonodes which was able to be examined.
Our case is thinkable a reticulum cell sarcoma that arose primarily from spinal extradural space and right psoas major muscle apart from lymphonodes.
