Schistosomus reflexus in a dog and a cat

Background: Schistosomus reflexus (SR) is a congenital anomaly, that the animal presents exposed abdominal and thoracic organs. The alterations includes limbs malformation, abnormal spinal column, liver and diaphragm hypoplasia, genitourinary and gastrointestinal changes, on this way, the fetus can not survive. The aim of this study was to report the first SR case in dog and cat in Brazil, and describe anatomical, pathological and radiographic changes. Case: The puppy had ventral midline defect in the abdominal and thoracic wall extending from the sternum to the pubis with viscera exposition, including the heart, lung, liver, stomach, intestine, spleen, kidneys, moreover right army was abnormal, however no spinal column was present. It was performed radiography to evaluate bone abnormalities, and was diagnosed agenesis of carpal, metacarpal and phalange bones. The kitten had ventral midline defect measuring 4 x 2 cm, in the abdominal wall and exposition of liver, stomach, intestine and spleen, as well as tibiotarsal joint arthrogryposis on both lags. It was performed fetus radiography and no spinal column change was diagnosed. Discussion: Schistosomus reflexus is a congenital abnormality common in ruminants. Although it was few reported in dogs and cats. The two cases in this study are the firsts reposts in Brazil in these especies. In our case, the dog had exposition of abdominal and thoracic organs and died one hour after born, similar to this, another author reported a case where the thoracic and abdominal evisceration and the puppy died ten minutes after born. However, in another case with abdominal evisceration only, the puppy survived for eight days. Probably it happened because respiratore function was not compromised. The kitten had abdominal opening only, in turn, other authors reported a case whose abdominal viscera exposition was by pelvic fissure, and another case, what presented thoracic and abdominal evisceration, like our dog case...

Ocorrência de adenocarcinoma endometrial em Oryctolagus cuniculus (Linnaeus, 1758): Relato de caso / Occurrence of endometrial adenocarcinoma in Oryctolagus cuniculus (Linnaeus, 1758): Case report

Endometrial adenocarcinoma is often view in rabbits at older age, disabling them for reproduction. Thepresente work aim to report the occurrence of endometrial adenocarcinoma in Oryctolagus cuniculus, in the cityof Belém, Pará. The animal come to death and it was referred for the performance of its necropsy, thereproductive tract was fixed in formaldehyde to continue the histopathological examination. Grossly, it wasverified that the uterine horn exhibited a dilated segment, vascularised and with friable tissue. Microscopicallyit was noticed tubular pattern formation with luminal expansion, anisocytosis, anisonucleosis and low mitoticrates. Then, due to the pathological characteristics, it suggests an occurrence of endometrial adenocarcinomain rabbits.(AU)
