| PICD | primary irritant contact dermatitis |
| nummular dermatitis | <dermatology> A form of eczema that is characterised by coin-shaped patches of inflamed skin. The cause is unknown but is related to a hypersensitivity reaction. A family history for allergies or atopic dermatitis is common in affected individuals. (13 Nov 1997) |

| deficiency dermatitis and diarrhoea, zinc | A genetic disease called acrodermatitis enteropathica is characterised by the simultaneous occurrence of skin inflammation (dermatitis) and diarrhoea. The skin on the cheeks, elbows and knees and tissue about the mouth and anus are inflammed. There is also balding of the scalp, eyebrows and lashes, delayed wound healing and recurrent bacterial and fungal infections due to immune deficiency. The key laboratory finding is an abnormally low blood zinc level reflecting impaired zinc uptake. Oral treatment with zinc is curative. (12 Dec 1998) |
| dermatitis | <pathology> Inflammation of the skin. (18 Nov 1997) |
| dermatitis aestivalis | Eczema recurring during the summer. (05 Mar 2000) |
| dermatitis, allergic contact | A contact dermatitis due to allergic sensitization to various substances. These substances subsequently produce inflammatory reactions in the skin of those who have acquired hypersensitivity to them as a result of prior exposure. (12 Dec 1998) |
| dermatitis ambustionis | Inflammation of the skin resulting from the action of heat. Synonym: dermatitis calorica, uritis. (05 Mar 2000) |
| dermatitis artefacta | Self-induced skin lesions resulting from habitual rubbing, scratching or hair-pulling, malingering, or mental disturbance. Synonym: dermatitis autophytica, factitial dermatitis, feigned eruption. (05 Mar 2000) |
| dermatitis-arthritis-tenosynovitis syndrome | <syndrome> Disseminated infection with Neisseria gonorrhoeae, causing skin lesions (often pustular or necrotic), plus synovitis of major joints (such as knee, ankle, elbow), and tendon sheaths. (05 Mar 2000) |
| dermatitis, atopic | A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema. (12 Dec 1998) |
| dermatitis atrophicans | A diffuse idiopathic atrophy of the skin involving the appendages. (05 Mar 2000) |
| dermatitis autophytica | Self-induced skin lesions resulting from habitual rubbing, scratching or hair-pulling, malingering, or mental disturbance. Synonym: dermatitis autophytica, factitial dermatitis, feigned eruption. (05 Mar 2000) |
| dermatitis calorica | Inflammation of the skin resulting from the action of heat. Synonym: dermatitis calorica, uritis. (05 Mar 2000) |
| dermatitis combustionis | Inflammation of the skin following a burn. (05 Mar 2000) |
| dermatitis congelationis | A cold injury that is accompanied by pallor, numbness and a loss of cold sensation. (27 Sep 1997) |
| dermatitis, contact | A type of acute or chronic skin reaction in which sensitivity is manifested by reactivity to materials or substances coming in contact with the skin. It may involve allergic or non-allergic mechanisms. (12 Dec 1998) |
