Bir çinçilada tesadüfen karşılaşılan akciğer trofoblast embolisi
Abstract
This case study presents the pathomorphological description of a pulmonary trophoblastic embolism in a female chinchilla, which died due to respiratory distress. Routine necropsy examination revealed the presence of multiple small and grey coloured foci, which presented with a hyperaemic and multifocal appearance on the surface of the lungs. Samples taken from the lung tissue were subjected to routine tissue processing and stained with haematoxylin-eosin (HE) and periodic acid-Schiff (PAS) reagents. Histopathological examination demonstrated one or more giant cells with rather large nuclei and a broad cytoplasm in the alveolar capillaries, which appeared as multifocal areas. These cellular structures were positive for PAS staining. And also, lymphocytic and histiocytic inflammatory cells infiltration were observed around the alveoli and bronchi-bronchioles

Incidental pulmonary trophoblastic embolism in a chinchilla
Abstract
Bu olguda, dişi bir çinçilanın akciğerlerinde trofoblastik emboli olgusu patomorfolojik olarak tanımlandı. Klinik olarak iştahsızlık ve solunum güçlüğü görüldüğü ve tedaviye yanıt vermeyerek öldüğü bildirildi. Yapılan rutin nekropsi yöntemi sonucu akciğerlerin solgun renkte yer yer hiperemik manzarada olduğu dikkati çekti. Yüzeyinde ise kimi alanlarda çok sayıda küçük ve kırmızı renkte odakların olduğu görüldü. Akciğerlerden alınan doku örnekleri rutin doku takibine alınarak Hematoksilen-eosin (HxE) ve Periodic acid-schiff (PAS) boyamaları yapıldı. Histopatolojik olarak, multifokal alanlar halinde alveoler kapillalarda tek veya birkaç büyük çekirdekli ve geniş sitoplazmalı trofoblast hücreleri gözlendi. Bu yapıların PAS boyamasında pozitif oldukları dikkati çekti. Ayrıca, alveoller ve bronş-bronşiollerin çevresinde lenfosit ve histiyositlerden oluşan yangısal hücre infiltrasyonları görüldü
