Pulmonary sequestration and bronchogenic cyst in a calf

İki günlük Simental ırkı bir buzağıda boyun bölgesinin alt kesimlerinde deri altında orta hat boyunca yerleşim gösteren kitle cerrahi olarak uzaklaştırıldı. Histolojik özellikleri bakımından kitlenin bronkojenik kist içeren ve gelişimini tamamlamamış bir akciğer dokusundan oluştuğu ortaya kondu. Bronşların hipoplastik oldukları ve kıkırdak içermedikleri, bronşçukların sayıca aşırı miktarda oldukları saptandı. Bu olgu sunumuyla ön bağırsak yapılış bozukluğu olarak buzağılarda akciğer sekestrasyonuyla birlikte bronkojenik kist olgusu bir arada ilk kez ortaya konmuş olup, bu bulgu akciğer sekestrasyonu ve bronkojenik kist oluşumunun benzer bir mekanizmaya dayandığını da göstermesi bakımından önemli bulundu.

Bir buzağıda rastlanan akciğer sekestrasyonu ve bronkojenik kist olgusu

Two-day-old, Simmental calf was presented with a pedinculated subcutaneous mass arising from midline of lower cervical region. The mass covered by the skin was removed surgically. Histological features of the mass were of underdeveloped lung tissue containing bronchogenic cyst. The bronchioles had excessive in number and the bronchi were hypoplastic and had no cartilagonous ring. The concurrent occurrence of a subcutaneous pulmonary sequestration and a bronchogenic cyst was noted as bronchopulmonary foregut malformation in a calf. As a result, this case report indicated that pulmonary sequestration and bronchonic cyst have common embryonic pathogenesis
