Gumma simulating neoplasm of the spinal cord has always been a rarity hardly deserving consideration, yet most works dealing with the clinical and pathologic aspects of syphilis of the nervous system mention gummatous involvement of the cord and spinal meninges. In all likelihood the reason why the clinical aspects have received so little consideration is that gumma of these structures usually does not attain significant size, and also its effects may be overshadowed by the manifestations of myelitis and meningitis, which are apt to precede or accompany it.
The case presented here may not add anything significant to the recognized pathology of syphilis of the nervous system but it is an interesting reminder of the vagaries of the disease and there are few examples of its kind on record.
