| pigmented purpuric lichenoid dermatosis | An eruption comprised of lichenoid papules variously pigmented from the haemosiderin of the associated purpura; found on the legs, usually in men over 40 years of age. Synonym: Gougerot and Blum disease. (05 Mar 2000) |
| pigmented retinal epithelium | Layer of unusual phagocytic epithelial cells lying below the photoreceptors of the vertebrate eye. The dorsal surface of the PRE cell is closely apposed to the ends of the rods and as discs are shed from the rod outer segment they are internalised and digested by the PRE. Do not have desmosomes or cytokeratins in some species. (18 Nov 1997) |
| pigmented villonodular synovitis | <radiology> Monoarthritis, young adults, erosions on BOTH sides of joint (!), probably inflammatory, haemosiderin deposited in synovium, articular cartilage preserved (despite extensive marginal erosions; similar to gout), NO calcification Differential diagnosis: TB (associated atrophy of muscle and bone), rheumatoid arthritis (symmetrical), synovial sarcoma (with or without calcified; outside joint), synovial osteochondromatosis (12 Dec 1998) |
| congenital giant pigmented nevus | These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (27 Sep 1997) |
| nevus, pigmented | A nevus containing melanin. The term is usually restricted to nevocytic nevi (round or oval collections of melanin-containing nevus cells occurring at the dermoepidermal junction of the skin or in the dermis proper) or moles, but may be applied to other pigmented nevi. (12 Dec 1998) |
| synovitis, pigmented villonodular | Outgrowths of synovial membrane composed of villi and fibrous nodules characterised histologically by haemosiderin- and lipid-containing macrophages and multinucleated giant cells. It usually occurs in the knee. (12 Dec 1998) |
| acute idiopathic polyneuritis | <neurology, syndrome> Acute infective polyneuritis that results in a form of peripheral neuropathy with temporary loss of movement and sensation due to inflammation of multiple nerves and loss of myelin. The exact cause is unknown but has been associated with an abnormal immune response to viral infection, particularly cytomegalovirus infection, in which there is cell-mediated immunity to a component of myelin. The disease may be autoimmune in origin and complete recovery can take up to six months. Synonym: Guillain-Barre syndrome (12 Jul 2000) |
| chronic idiopathic jaundice | <syndrome> An inherited disorder (autosomal recessive) that is characterised by long-standing mild jaundice. This occurs secondary to an abnormality in the transport of bilirubin from the liver to the biliary system. This leads to an accumulation of bilirubin in the liver. Avoidance of alcohol and medications which can affect the liver is important. Inheritance: autosomal recessive. (27 Sep 1997) |
| chronic idiopathic xanthomatosis | Vague or indefinite term for inherited abnormalities of lipid metabolism leading to xanthoma formation (e.g., primary familial xanthomatosis). (05 Mar 2000) |
| primary idiopathic macular atrophy | 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) |
| purpura, thrombocytopenic, idiopathic | Thrombocytopenia occurring in the absence of toxic exposure or a disease associated with decreased platelets. It is mediated by immune mechanisms, in most cases IgG autoantibodies which attach to platelets and subsequently undergo destruction by macrophages. The disease is seen in acute (affecting children) and chronic (adult) forms. (12 Dec 1998) |
| hyperostosis, diffuse idiopathic skeletal | A disease of elderly men characterised by large osteophytes that bridge vertebrae and ossification of ligaments and tendon insertions. (12 Dec 1998) |
| diffuse idiopathic skeletal hyperostosis | A form of degenerative arthritis characteristically associated with flowing calcification along the sides of the vertebrae of the spine and commonly with inflammation (tendinitis) and calcification of the tendons at their attachments points to bone. Because areas of the spine and tendons can become inflamed, antiinflammatory medications (NSAIDs), such ibuprofen, can be helpful in both relieving pain and inflammation. Also called Forestier's disease. (12 Dec 1998) |
| idiopathic | Of the nature of an idiopathy, self originated, of unknown causation. (18 Nov 1997) |
