Vesicle

An elevation of the skin or mucous membrane containing a watery fluid and less than 5 mm in diameter.


Small bladder or cavity.


A small blister-like elevation of the skin containing clear fluid.


A small watery lesion produced by the skin.


A small pouch, sac, or hollow organ, usually filled with fluid; examples include blisters and the seminal vesicles (located behind the bladder in males) contribute fluid to the ejaculate. A s kin vesicle is generally less than half a centimeter (a quarter of an inch) in diameter.


A very small blister in the skin, often no bigger than a pinpoint, that contains a clear fluid (serum). Vesicles occur in a variety of skin disorders, including eczema and herpes.


A small blister-like elevation on the skin containing serous fluid. Vesicles may vary in diameter from a few millimeters to a centimeter. They may be round, transparent, opaque, or dark elevations of the skin, sometimes containing seropurulent or bloody fluid. In sudamina, they result from sweat that cannot escape from the skin; in herpes, they are mounted on an inflammatory base, having no tendency to rupture but associated with burning pain. In herpes zoster, they follow dermatomes. In dermatitis venenata, they result from contact with poison ivy or oak and are accompanied by great itching. They are also seen in dermatitis herpetiformis or multiformis. In impetigo contagiosa, they occur, esp. in children, in discrete form, flat and umbilicated, filled with straw-colored fluid, with no tendency to break. They dry up, forming yellow crusts with little itching. They are also seen in vesicular eczema, molluscum contagiosum, miliaria (prickly heat or heat rash), chickenpox, smallpox, and scabies.


Small blister or sac containing clear fluid, lying within or just beneath the epidermis.


A tiny bubble, often containing transparent fluid, that develops at a location of skin injury. The term is also employed to denote any diminutive sac-like structure within the body.


A diminutive pouch, particularly one filled with fluid; a vesicle on the skin, akin to that observed in varicella (chickenpox).


A vesicle refers to a small fluid-filled sac or bladder, commonly known as a blister, which is typically observed in conditions such as chickenpox.
