VAGINAL HEMANGIOMA IN A WHITE RHINOCEROS (CERATOTHERIUM-SIMUM-SIMUM)

A female white rhinoceros (Ceratotherium simum simum) had repeated episodes of vaginal hemorrhage beginning in February 1981 and continuing until January 1991 with no apparent clinical effects. The vaginal hemorrhage became a daily event in January 1991; therefore, the rhinoceros was immobilized and examined. A nodular mass was palpated and biopsied in the cranioventral vagina. A second immobilization and endoscopic exam was performed on 23 January 1991. Although no clinical effects of the hemangioma were evident, the reproductive effects of the hemangioma are unknown.
