Spinal epidermoid cyst in the mouse. An ultrastructural study.
Ultrastructural features of epidermoid cysts in the spinal leptomeninges were studied in two strains of mouse. Although the cysts were lined by stratified squamous epithelium, the normal sequence of epidermal differentiation in this epithelium was not observed in that the basal cell layer was absent in certain areas. The morphological features and genesis of this  phenomenon are briefly discussed.
