Unilateral Luteoma in the Ovary of a Dog

Öz

In this case, ovarial luteoma in the left ovary in a 13-year-old Terrier was defined both macroscopically and microscopically. The dog had a history of vomiting and anorexia for a week. In palpation, sensitivity observed on the left abdominal region of the animal. Ultrasonographically a hypoechoic, round mass with homogeny architecture, 13 x 11 cm in size, located in the left abdominal region was found. The both ovary with tumoural mass and uterus were taken by operation and masses were referred to pathology laboratory for histopathological examination. Macroscopically, the left ovarial mass, 13 x 11 x 8 cm in size, was moderately firm, round, multilobulated and encapsulated and the cut surface had a yellowish appearance. There were focal areas of hemorrhages and necrosis. In microscopical examination, neoplastic cells were arranged in irregular shaped solid sheet. The nuclei were small, round to oval and had coarsely stippled chromatin. The amount of cytoplasm varied from scant to moderate and was faintly eosinophilic and finely granular or vacuolated. Luteinized cells had prominent eosinophilic cytoplasm and pale staining nuclei. Few mitotic figures were seen in the sections. The left ovary was completely invaded by neoplastic cells and the normal histological architecture was not observed. However in the right ovary and uterus was not found pathological lesion by histological examination. In the light of the macroscopical and microscopical findings the tumour was found compatible with ovarial luteoma.

Bir Köpekte Tek Taraflı Luteoma Olgusu

Öz

      Bu olguda, Terrier ırkı, dişi, 13 yaşlı köpeğin sol ovaryumunda nadir olarak şekillenen luteomanın makroskobik ve mikroskobik özellikleri tanımlanmıştır. Klinik olarak bir haftadan beri süren iştahsızlık ve kusma bulguları ile Veteriner Fakültesi Kliniklerine getirilen hayvanın ultrasonografik muayenesinde batın içerisinde 13x11 cm boyutlarında tamamen hipoekoik ve yer yer normal dokulara göre farklı ekojenitede homojen yapı gösteren kitleye rastlandı. Yapılan operasyonda tümöral kitle ile beraber ovaryum ve uterus, makroskobik ve histopatolojik inceleme için patoloji laboratuvarına gönderildi.  Makroskobik muayenesinde kitlenin 13x 11x 8 cm boyutlarında, orta sert kıvamlı, kesit yüzü krem renkte ve yer yer kanama alanları içerdiği görüldü. Histopatolojik incelemede, sol ovaryumun tamamen tümöral doku ile kaplanmış olduğu ve normal ovaryum yapısına ait hiçbir histolojik doku içermediği dikkati çekti. Tümörün hücre sınırları belirgin, eozinofilik sitoplazmalı, sitoplazmasında yağ vakuolleri olan, açık veziküler çekirdekli, belirgin çekirdekçiğe sahip, yer yer ince bağ doku kordonları ile birbirinden ayrılan poligonal hücre kümelerinden oluştuğu dikkati çekti.  Tümöral dokuda yer yer mitotik figürlere rastlandı. Bazı alanlarda nekroz ve kanama görüldü. Bu olayda, makroskobik ve histopatolojik inceleme sonucunda sol ovaryumda nadir görülen luteoma olgusu tanımlanmıştır.
