Mycetyoma in a horse—curtains

Abstract

The case report describes a highly malignant fibrosarcoma in a 15 year old Himalayan female cat presented to the clinic with a history of uterine hemorrhage and body weight loss. Physical examination revealed a large round mass of about 2-3 cm in the regions of the posterior abdomen. Radiographic examination confirmed the presence of a round mass which appeared to be associated with the uterus. At necropsy an irregular relatively firm single intramural mass of 2 to 3 cm diameter was detected in the mid-portion of the left horn of the uterus. Metastases were present in the lungs, thoracic pleura, diaphragm and mesenterium. The diagnosis of uterine fibrosarcoma was based on the histological mesenchymal spindle cell appearance of the tumor cells and the results of the immunohistochemical findings. Based on the negative results of Smooth Muscle Actin (SMA) antigen for the tumor cells, a final diagnosis of fibrosarcoma was made. To the best knowledge of the authors this is the first diagnosis of a spontaneous uterine fibrosarcoma in a cat without signs of uterine inflammation or pyometra and with widespread metastases. http://www.ijvm.org.il/node/340 Israel Journal of Veterinary Medicine, December 2013 68(4) 246-251 Case Report: Contagious Ecthyma Deviations in the Anatomical Appearance of Lesions in an Outbreak in Lambs in Israel Bouznach A, Hahn S, Stram Y, Menasherov S, Edery N, Shicaht N, Kenigswald G, Perl S 1 Department of Pathology, Kimron Veterinary Institute, 50250 Bet Dagan, Israel. 2 Department of Virology, Kimron Veterinary Institute, 50250 Bet Dagan, Israel. 3 “Hachaklait” Veterinary Services POB 3039, 38900 Caesaria, Israel. * Corresponding author: Prof. S.
