(n.) A contagious affection of the skin due to the presence of a vegetable parasite, and forming ring-shaped discolored patches covered with vesicles or powdery scales. It occurs either on the body, the face, or the scalp. Different varieties are distinguished as Tinea circinata, Tinea tonsurans, etc., but all are caused by the same parasite (a species of Trichophyton).

Vesicle
Definition:
(n.) A bladderlike vessel; a membranous cavity; a cyst; a cell.
(n.) A small bladderlike body in the substance of vegetable, or upon the surface of a leaf.
(n.) A small, and more or less circular, elevation of the cuticle, containing a clear watery fluid.
(n.) A cavity or sac, especially one filled with fluid; as, the umbilical vesicle.
(n.) A small convex hollow prominence on the surface of a shell or a coral.
(n.) 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.
Example Sentences:
