| 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) |
| crural ring | The superior opening of the femoral canal, bounded anteriorly by the inguinal ligament, posteriorly by the pectineus muscle, medially by the lacunar ligament, and laterally by the femoral vein. Passageway by which many lymphatics from lower limb pass to abdomen. Accommodates enlargement of femoral vein in Valsalva manoeuvre. Often occupied by a lymph node (Cloquet's) and is the site of femoral hernias. Synonym: annulus femoralis, crural ring. (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. Anetos, relaxed, + derma, skin (05 Mar 2000) |
| primary neuroendocrine carcinoma of the skin | A rare malignant cutaneous tumour seen in sun-exposed skin of elderly patients composed of dermal nodules of small round cells with scanty cytoplasm in a trabecular pattern; the tumour cells contain cytoplasmic dense core granules resembling neurosecretory granules seen in Merkel cells. Synonym: primary neuroendocrine carcinoma of the skin, trabecular carcinoma. (05 Mar 2000) |
| primary skin graft | A skin graft transferred immediately after the creation of a raw area. (05 Mar 2000) |
| sailor's skin | Dry, wrinkled skin with presence of dry premalignant keratoses; observed most commonly in fair-skinned, blue-eyed persons who are exposed by occupation or sport to sunshine for prolonged periods and over many years. Synonym: golfer's skin, sailor's skin. (05 Mar 2000) |
| P ring | <microbiology> One of the bushes at the base of the flagellum of gram-negative bacteria, anchoring it in the peptidoglycan layer of the cells wall. Lies below the L ring. (18 Nov 1997) |
| 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) |
| schatzki ring | <radiology> B ring of distal oesophagus, squamo-columnar junction, with or without hiatus hernia, intemittent symptoms if 13-20 mm, steakhouse syndrome, Treatment: balloon or bougie see: oesophageal webs and rings (12 Dec 1998) |
| schatzki's ring | A congenital anatomic narrowing in the lower 1/3 of the oesophagus that is the result of inappropriate embryological development of the oesophagus. Symptoms include difficulty swallowing and chest pain (under the sternum). Treatment involves the use of a fibreoptic endoscope using a dilator to open up the narrowed segment of the oesophagus.

| heterocyclic compounds, 1-ring | A class of organic compounds containing a ring structure made up of more than one kind of atom, usually carbon plus another atom. The ring structure can be aromatic or nonaromatic. (12 Dec 1998) |
| heterocyclic compounds, 2-ring | A class of organic compounds containing two ring structures, one of which is made up of more than one kind of atom, usually carbon plus another atom. The heterocycle may be either aromatic or nonaromatic. (12 Dec 1998) |
| heterocyclic compounds, 3-ring | A class of organic compounds containing three ring structures, one of which is made up of more than one kind of atom, usually carbon plus another atom. The heterocycle may be either aromatic or nonaromatic (12 Dec 1998) |
| heterocyclic compounds, bridged-ring | A class of organic compounds which contain two rings that share a pair of bridgehead carbon atoms. (12 Dec 1998) |
