Incidence of Multiple Mammary Tumors and Fibroadenoma in Pathological Study of Udder Affections in Camel (Camelus dromedarius)

Abstract

Aims of the Study: To investigate the general histopathological pictures found in the udder tissue of camel (Camelus dromedarius) with emphasis on different types of tumors. Place and Duration of Study: The study was undertaken in the Department of Pathology, Central Veterinary Research Laboratory, Ministry of Animal Resource and Fisheries, Khartoum, Sudan in 2009. Study Design: 150 samples of camel udder tissues were obtained from Tumbool abattoir in         Al-Gazeera State, gross and histopathological pictures were studied. Methodology: The macroscopic pictures of samples were reviewed and described, then histopathological lesions were studied using H&E stain. Lastly immunohistochemical staining was done using estrogen and progesterone antibodies in one sample showing mixed tumors. Results: Out of 150 samples studied, 45(30%) showed neoplastic masses, 23(51.11%) of them were benign and 22(48.89%) were malignant. Different pathological pictures were reported, but only one showed multiple mammary neoplasms contain papillary carcinoma and fibroadenoma.  Conclusion: Mammary tumors were detected for the first time in Sudanese camel and completely confirmed by using histopathological methods.
