Intracystic Papillary Carcinoma in the Mammary Gland of She-Camel (Camelus dromedaries), Sudan

Aims of the Study: Survey of udder disorders over one year to investigate the histopathological lesions of tumors in camel (Camelus dromedarius).

Place of Study: The study was undertaken in the Department of Pathology, Central Veterinary Research Laboratory, Ministry of Animal Resource and Fisheries, Khartoum, Sudan.

Study Design: 45 tumors of camel udder tissues were obtained from Tumbool abattoir Al-Gazeera State; the gross and histopathological lesions 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, progesterone antibodies and CytoKeratin 5/6.

Results: A survey over a one year was done, 45 tumours were diagnosed, of which 23 were malignant. Only one tumour had features suggestive of intracystic papillary carcinoma (IPC).

Conclusion: To the best of our knowledge this may be the first intra cystic papillary carcinoma reported in the udder of a dromedary worldwide.
