Vesicle vs. Papule — What's the Difference?

(Cytology) A membrane-bound structure within a cell in which materials such as enzymes are transported or stored.

A papule is a circumscribed, solid elevation of skin with no visible fluid, varying in area from a pinhead to 1 cm. Papules can be brown, purple, pink or red in color, and can cluster into a papular rash.

(Anatomy) A sac or cyst, especially one containing fluid.

A small pimple or swelling on the skin, often forming part of a rash.

(Medicine) A blister of the skin.

A small, solid, usually inflammatory elevation of the skin that does not contain pus.

(Geology) A cavity formed in volcanic rock by entrapment of a gas bubble during solidification.

A small, inflammatory, irritated spot on the skin, similar in appearance to a pimple, but not containing pus.

(cytology) A membrane-bound compartment found in a cell.

Same as Papula.

A small bladder-like cell or cavity, as:

A small inflamed elevation of skin that is nonsuppurative (as in chicken pox)

(botany) A small sac filled with juice, one of many constituting the pulp of a fruit such as an orange, lemon, or grapefruit.

A small sac or cyst or vacuole, especially one containing fluid. A blister formed in or beneath the skin, containing serum. A bleb.

(anatomy) A pocket of embryonic tissue that is the beginning of an organ.

(geology) A small cavity formed in volcanic rock by entrapment of a gas bubble during solidification.

A bladderlike vessel; a membranous cavity; a cyst; a cell.

A small bladderlike body in the substance of a vegetable, or upon the surface of a leaf.

A small, and more or less circular, elevation of the cuticle, containing a clear watery fluid.

A cavity or sac, especially one filled with fluid; as, the umbilical vesicle.

A small convex hollow prominence on the surface of a shell or a coral.

A small cavity, nearly spherical in form, and usually of the size of a pea or smaller, such as are common in some volcanic rocks. They are produced by the liberation of watery vapor in the molten mass.

A small anatomically normal sac or bladderlike structure (especially one containing fluid)
