Zusammenfassung:An 11-year-old female terrier brought to our clinic was diagnosed with chondroma located on the caudolateral side of the right distal humerus. During the clinical examination of the dog, swelling and lameness were observed on right forelimb. Following the operation, the subject had no lameness after removing the mass. Postoperative follow-up was done by phone with the owner of the patient in 6th and 12th months, and no lameness and swelling in the region was reported. The tumoral mass was removed easily from underlying tissue without any attachment during the operation. The tissue sample from the specimen was routinely processed and stained with Hematoxylin-Eosin for histopathological examination. The tumoral mass was 5 x 3.4 x 1.9 cm in size, 25 g in weight and hard in texture. Cross sections of the mass were white and had a multilobulated appearance surrounded by connective tissue. The histological examination showed that the tumoral mass was divided into lobules by a thin fibrous stroma. The neoplastic cells were uniform in shape and size, and they were composed of well-differentiated mature chondrocytes. While the tumoral mass was poorly vascularized with a few foci of necrotic areas, mitosis was not observed within the tumoral cells. 11 yaşlı Terrier ırkı dişi bir köpekte kiliniklerimizde sağ distal humerusunun kaudolateraline lokalize olan kondroma teşhisi kondu. Köpeğin klinik muayenesinde sağ ön ekstremitesinde şişkinlik ve topallık izlendi. Olgunun operasyonundan sonra kitlenin çıkarılmasını takiben topallık kalmadı. Postoperatif izleme döneminde hasta sahibi ile 6. ve 12. aylarda telefon bağlantısı yapıldı, olguda herhangi bir topallık ve bölgesel şişkinlik olmadığı bildirildi. Operasyon sırasında tümoral kitle, alt dokularla bağlantısı olmaksızın kolayca çıkarıldı. Tümöral kitlenin cerrahi olarak uzaklaştırılmasından sonra örneklerden alınan dokular rutin doku takibinden sonra histopatolojik muayene için Hematoksilen-eosin ile boyandı. Tümöral kitle sert kıvamda, 25 g ağırlığında ve 5 x 3,4 x 1,9 cm boyutlarındaydı. Kitlenin kesit yüzü beyaz renkte ve konnektif bir doku ile çevrili multilobüler bir görünüme sahipti. Histolojik muayenede tümöral kitlenin, ince fibröz bir doku ile lobüllere bölündüğü gözlendi. Neoplastik hücreler üniform şekil ve büyüklükte, iyi differensiye olgun kondrositlerden oluşmuştu. Tümöral kitle damarlardan yoksun, birkaç nekrotik bölgeye sahip iken tümör hücrelerinde mitozis gözlenmedi.
