Ringworm \Ring"worm"\, n. (Med.)
   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}).
