| piebald skin | Patchy absence of the pigment of scalp hair, giving a streaked appearance; patches of vitiligo may be present in other areas sue to absence of melanocytes; often transmitted as an autosomal dominant trait and may be associated with neurological defects or eye changes . Compare: Waardenburg syndrome. Synonym: piebald skin, piebaldism. (05 Mar 2000) |
| pigment cell of skin | Special cells in the skin and the eye that synthesise melanin pigments. Clusters of melanocytes often appear on the skin as moles. In fish and reptiles, the pigments are stored in melanosomes (chromatophores) that can be redistributed in the cytoplasm to change pigment patterns. Synonym: melanodendrocyte. Origin: melano-+ G. + kytos, a hollow (cell) (29 Sep 1997) |

| porcupine skin | Hyperkeratosis, hypergranulosis, and reticular degeneration in the upper epidermis. Generalised epidermolytic hyperkeratosis is present in bullous congenital ichthyosiform erythroderma. Localised epidermolytic hyperkeratosis may be found in epidermal nevi and benign keratoses. Synonym: porcupine skin. (05 Mar 2000) |
| primary macular atrophy of skin | Atrophoderma in which the skin becomes bag like and wrinkled. Synonym: atrophia maculosa varioliformis cutis, atrophoderma maculatum, macular atrophy, primary idiopathic macular atrophy, primary macular atrophy of skin. Origin: G.

| scalded skin syndrome | <syndrome> A potentially serious side effect of infection with the staph (staphylococcus) bacteria that produces a specific protein which loosens the cement holding the various layers of the skin together. This allows blister formation and sloughing of the top layer of skin. If it occurs over large body regions it can be deadly (just like a large surface area of the body having been burned). It is necessary to treat scalded skin syndrome with intravenous antibiotics and to protect the skin from allowing dehydration to occur if large areas peel off. The disease occurs predominantly in children under 5 years of age. It is known formally as staphyloccoccal scalded skin syndrome and as ritter disease. (12 Dec 1998) |
| hidden nail skin | 1. The thin, condensed, eleidin-rich layer of epidermis which procedes and initially covers the nail plate in the embryo. It normally degenerates by the eighth month except at the nail base where it remains as the cuticle of the nail. 2. The corneal layer of epidermis overlapping and in direct contact with the nail root proximally or the sides of the nail plate laterally, forming the undersurface of the nail wall or nail folds of nail. Synonym: hidden nail skin, perionychium. 3. The thin skin adherent to the nail at its proximal portion. Synonym: epionychium. Origin: G. Epi, upon, + onyx (onych-), nail (05 Mar 2000) |
| pupillary-skin reflex | Dilation of the pupil following scratching of the skin of the neck. Synonym: ciliospinal reflex, cutaneous pupil reflex, cutaneous-pupillary reflex, skin-pupillary reflex. (05 Mar 2000) |
| sex skin | The skin of the genital regions of the Macaca mulatta and other primates which becomes hyperaemic during estrus; at the same time the dermis becomes gelatinous and the epidermis thickened. (05 Mar 2000) |
| shagreen skin | An oval-shaped nevoid plaque, skin-coloured or occasionally pigmented, smooth or crinkled, appearing on the trunk or lower back in early childhood; sometimes seen with other signs of tuberous sclerosis. Synonym: shagreen patch. (05 Mar 2000) |
