Abstract
The aim of this case report was to give information about histopathological diagnosis, operative process and postoperative process of facial subcutaneous leiomyosarcoma in a cat. A 3-year-old chinchilla breed female cat was brought to our clinic with a complaint of a nut-sized mass under the right ear in the head area. A clinical examination of the case found a mass under the right ear with a diameter of about 2.5 cm, elastic consistency, hemorrhagic foci in places. In the postoperative follow-up of the case, it was found that recurrence was observed approximately in the 4th month, but the general condition of the cat was good and had kittens. The sections prepared from the tissue samples were dyed with hematoxylene-eosin and Masson's trichrome staining technique. Histopathological examinations showed atypical muscle cells in the form of oval or spindle shaped novelties that made bands or vortices that gave arms in various directions. In Masson's trichrome painting, it was noted that these cells were painted red. As a result of all these assessments, the mass was histomorphologically identified as leiomyosarcoma. This presentation shows that leiomyosarcoma can be seen in cats, although rare, and cases may relapse in the postoperative period.

Abstract
Bu olgu sunumu ile bir kedideki fasiyal subkutanöz leomiyosarkomun operatif işlemi histopatolojik tanısı ve postoperatif süreci hakkında bilgi verilmesi amaçlandı. Olgumuzu kliniğimize baş bölgesinde sağ kulağın altında fındık büyüklüğünde bir kitle şikâyeti ile getirilen 3 yaşında, chinchilla ırkı bir dişi kedi oluşturdu. Kitlenin sağ kulağın altında yaklaşık 2,5 cm çapında, elastik kıvamlı, yer yer hemorajik odakların olduğu bir kitle tespit edildi. Genel anestezi altında kitle total olarak eksize edildi. Olgunun postoperatif takibinde yaklaşık 4. ayda nüks olduğu ancak kedinin genel durumunun iyi olduğu ve yavruladığı bilgisine ulaşıldı. Alınan doku örneklerinden hazırlanan kesitler histopatolojik incelemeler amacıyla hematoksilen-eozin ve Masson’un trikrom boyaması ile boyandı. Histopatolojik olarak yapılan incelemelerde, çeşitli yönlere kollar veren bantlar veya girdaplar yapmış oval veya iğ şeklinde görünüşlü atipik kas hücreleri görüldü. Yapılan Masson’un trikrom boyamasında bu hücrelerin kırmızı renkte boyandığı dikkati çekti. Kitle histomorfolojik olarak leomiyosarkom olarak tanımlandı. Leomiyosarkom olgularıyla kedilerde nadirde olsa karşılaşılabileceği postoperatif dönemde nüks olabileceği görüldü.
