VesicleThe principal diseases in which vesicles are found, and their chief features, are: - Eczema; in patches, minute and closely aggregated, and rupturing in a day or two, except where the epidermis is very thick.
- Dermatitis multiformis; Lesions of larger size and greater duration, and frequently accompanied with other lesions of a pustular character.
- Erysipelas; Lesion situated on a diffused inflamed base, usually on the face.
- Erythema multiforme; Associated with macules and patches of erythema.
- Herpes; One or more groups of three or four vesicles of moderate size, and not packed together so closely as in eczema. They usually last a few days, and dry down into a small scale or crust, except on the genitals, where they rupture promptly.
- Impetigo contagiosa; Medium-sized vesicles, lasting a few dayi and drying down to form crusts, occurring on any part of the body.
- Scabies; Small, pointed vesicles, usually met with on the hands and fingers.
- Sodamina; Minute, disseminated vesicles, corresponding to the sudoriparous ducts.
- Varicella; Vesicles of medium size, which may or may not be umbilicated.
- Variola; Umbilicated vesicles succeeding papules.
- Zoster; Vesicles of good size, seated on inflamed patches, and following the course of a nerve-trunk.
