Acquired epidermoid tumour in the thoracic spinal canal

Abstract

Acquired spinal epidermoid tumours are rare, and probably caused by skin fragments that have been transplanted by trauma or lumbar puncture. They almost always occur in the region of the cauda equina. We present an acquired spinal epidermoid tumour at the T 10 level, with pathological confirmation. A skin fragment had migrated to a site where it developed into a tumour.
