| 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 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) |
| anterior epithelium of cornea | The stratified squamous epithelium covering the outer surface of the cornea; it is smooth, consists usually of five layers of cells, and contains numerous free nerve endings. Synonym: epithelium anterius corneae. (05 Mar 2000) |
| Barrett's epithelium | Columnar oesophageal epithelium seen in Barrett's syndrome. (05 Mar 2000) |
| germinal epithelium | A cuboidal layer of peritoneal epithelium covering the gonads, once thought to be the source of germ cells. (05 Mar 2000) |
| reduced enamel epithelium | The several layers of the enamel organ remaining on the enamel surface after formation of enamel is completed. Synonym: reduced enamel epithelium. (05 Mar 2000) |
| gingival epithelium | A stratified squamous epithelium that undergoes some degree of keratinization and covers the free and attached gingiva. (05 Mar 2000) |
| glandular epithelium | Epithelium composed of secretory cells. (05 Mar 2000) |
| pavement epithelium | Epithelium composed of a single layer of flattened scalelike cells, such as mesothelium, endothelium, and that in the pulmonary alveoli. Synonym: pavement epithelium. (05 Mar 2000) |
| respiratory epithelium | The pseudostratified ciliated epithelium that lines the conducting portion of the airway, including part of the nasal cavity and larynx, the trachea, and bronchi. (05 Mar 2000) |
| mesenchymal epithelium | The flat epithelium derived from mesenchymal cells found lining certain connective tissue spaces such as the anterior chamber of eye, perilymph spaces in the ear, and subdural and subarachnoid spaces. (05 Mar 2000) |
| ciliated epithelium | Any epithelium having motile cilia on the free surface. (05 Mar 2000) |
