An eruption of deep-seated vesicles on an erythematous base; the term embraces two distinct affections; h. simplex and h. zoster.

A vesicular skin disease.

A skin disease consisting of clustered eruptions.

A vesicular disease, which, in most of its forms, passes through a regular course of increase, maturation, decline, and termination, in from 10 to 14 days. The vesicles arise in distinct, but irregular clusters, which commonly appear in quick succession, and near together, on an inflamed base; generally attended with heat, pain, and considerable constitutional disorder. The term, like all others which refer to cutaneous diseases, has not been accurately defined. Bateman has the following varieties: 1. Herpes Phlyctaesnodes, Herpes miliaris, Ecphlysis Herpes Miliaris, Nirles, (F.) Dartre phlyctenoide, in which the vesicles are milletsized; pellucid; clusters commencing on an uncertain part of the body, and being progressively strewed over the rest of the surface; succeeded by fresh crops. 2. Herpes Zoster, Zoster, Zona ignea seu serpiginosa, Ignis Persicus, Cinzilla, Cingulum, Sacer ignis, Ecphlysis Herpes zoster, Herpes periscelis, Erysipelas zoster seu phlyctaenoides seu pustulosa, Zona, Circinus, Perizoma, (F.) Ceinture, C. dartrense, Feu Persique, erysipele pustuleux, Shingles, (Prov.) Gruels, in which the vesicles are pearl-sized; the clusters spreading round the body like a girdle; at times confluent, and occasionally preceded by constitutional irritation. 3. Herpes Circinatus, Formica ambulatoria, Annulus repens, Herpes Serpigo, Serpigo, Ecphlysis Herpes Circinatus, Ringworm, Vesicular Ringworm, consisting of vesicles with a reddish base, uniting in rings; the area of the rings slightly discoloured, often followed by fresh crops. 4. Herpes Labialis, and 5. Herpes Praeputialis, Aphthae praeputii, Ulcuscula proeputii, appearing, respectively, on the lips and prepuce. 6. Herpes Iris, Iris, Rain-how-warm, occurring in small circular patches, each of which is composed of concentric rings of different colours. To these may be added, Herpes Exedens, H. esthiomenus seu depascens seu ferus seu estiomenus seu ferox, Ecphlysis Herpes exedens, Darta excoriativa seu maligna, Lupus non exedens, Formica corrosiva, Formix, Papula fera, Ulcerative Ringworm, Agria, (F.) Dartre rongeante, in which the vesicles are hard; clusters thronged; fluid dense, yellow or reddish, hot, acrid, corroding the subjacent skin, and spreading in serpentine trails. All the varieties demand simply an antiphlogistic treatment, when attended with febrile irritation. The herpes circinatus, alone, requires the use of astringent applications which have the power of repressing the eruption.

Skin-disease marked by clusters of small vesicles.

A general term to signify grouped lesions of the skin, usually vesicular, on an erythematous base. Probably due to a trophic disturbance of terminal nerve filaments.

A cutaneous inflammation.
