Iatrogenic Intraspinal Epidermoid Tumor

Iatrogenic spinal epidermoid tumors are rare and implanted. Implanted skin fragment by trauma or lumbar puncture is thought to be a possible cause. Because of the lag in time between the lumbar puncture and the development of a symptomatic tumor, this relationship is usually overlooked and can cause a delay in diagnosis. We present a case of intraspinal epidermoid tumor developed 7 years after a lumbar puncture.

Intraspinal Epidermoid Tumor with Previous Lumbar Puncture

Congenital intraspinal epidermoid tumors, while rare, do occur ; that they are related to spinal puncture is less well understood. This article describes the case of a 10 year-old boy with intraspinal epidermoid tumor, who five years previously had undergone lumbar puncture. A striking clinical features of this case is pain in the lower extremity. In this report, we review the literature and discuss the probable developmental mechanism of such tumor.
