Adenocarcinoma Papilar Ovárico E Hiperplasia Endometrial Quística.

Abstract

A 6-year-old female mixed-breed dog was presented to Vetermedicas veterinary clinic for ultrasound examination. The primary finding was a mass in the dorsal mesogastrium, which led to a referral for exploratory laparotomy. Initial physical examination revealed abdominal distension compatible with ascites and panting. A complete blood count and biochemical profile were performed as preoperative tests, which revealed no abnormalities. However, a repeat ultrasound and chest x-ray were performed, revealing fluid in the right and left hemithorax. Two days later, free fluid was collected, draining a total of 500 ml, consistent with transudate. Fine needle puncture (FNA) of the reactive thoracic lymph nodes was performed, followed by surgery, revealing a mass located in the right ovary. The uterus and ovary were removed, and an incisional biopsy was performed for histopathology. The patient presented no changes after surgery. Ultrasound checks were performed, which found an absence of fluid in both hemithorax’s. After a week, the patient was discharged. At this check-up, the pathology results were announced, which were papillary ovarian adenocarcinoma, cystic endometrial disease, and polycystic ovary disease. An ultrasound check-up was also performed, revealing a mass occupying the right kidney. An appointment was scheduled with the oncology department twenty days later to initiate treatment. Blood tests and imaging were performed. However, the owners, due to financial limitations, decided not to undergo clinical testing. It is concluded that adenocarcinoma is a highly invasive disease, with an asymptomatic presentation and difficult diagnosis, which leads to late treatment and low survival rates.
