Dermoid cysts of the ovary may consist only of a wall of connective tissue lined with epidermis and containing distinctly epidermic scales which, however, may be rolled up in firm masses of a more or less soapy consistency; this variety is called by Orth epidermoid cyst; or, according to Warren, a form of cyst made up of skin containing small and ill-defined papillae, but rich in hair follicles and sebaceous glands.

Leale remarks that as common warts of the skin are collections of vascular papillae, admitting of separation without injury to their exceptionally thick layer of epidermis, they are probably better for the purposes of skin-grafting than ordinary skin of less vitality or vascularity.

Thiersch contends that healing of a granulated surface results first from a conversion of the soft, vascular granulation-papillae, by contraction of some of their elements into young connective-tissue cells, into "dry, cicatricial papillae," actually approximating the surrounding tissues, thus diminishing the area to be covered by epidermis; and, secondly, by the covering of these papillae by epidermic cells.

Ichthyosis is a disease of the skin characterized by a morbid development of the papillae and thickening of the epidermic lamellae; according as the skin is affected over a larger or smaller area, or only the epithelial lining of the follicles, it is known as ichthyosis diffusa, or ichthyosis follicularis.

The histology of ainhum shows it to be a direct ingrowth of epithelium, with a corresponding depression of surface due to a rapid hyperplasia that pushes down and strangles the papillae, thus cutting off the blood supply from the epithelial cells, causing them to undergo a horny change.
