The tumor started as a small ulcerated mass failed to respond to antibiotics treatment and reached 15 cm in diameter. The mass was removed surgically and histopathologically diagnosed as a squamous cell carcinoma. To the best of our knowledge, this is the first report of a SCC in the fatty tail of an Awassi sheep in Jordan in the veterinary literature.

AN UNUSUAL PRESENTATION OF LOCALY INVASIVE SQUAMOUS CELL CARCINOMA IN THE FATTY TAIL OF AWASSI SHEEP. Mirror of Research in Veterinary Sciences and Animals . MRVSA 1(1),13-16. INTRODUCTION Cutaneous Squamous cell carcinoma in sheep has been reported in different countries throughout the world (Hawkins et al., 1981, TiLbrook, 1992, Foreyt et al., 1991, Tustin et al.,1982; Ramadan et al., 1991). This neoplasm has been described in different breeds of sheep and in different locations throughout the body (Foreyt et al., 1991, Mendez et al., 1997 and Ramadan et al., 1991). There are different factors associated with the induction of the neoplasm such as, solar radiation, papillomavirus, genetics and other undetermined factors (Vanselow and Spradbrow, 1982, Hawkins et al., 1981and Uzal et al., 2000). In this report, clinical and pathological findings of the SCC in Awassi sheep are described.
