Granulosa-cell tumor associated with pyometra in a seven months old cat
ABSTRACT Ovarian neoplasias in cats are rare, and are associated with advanced ages, as well as non-iatrogenic pyometra. The objective of the present study was to report a case of a young cat showing signs of a rare neoplasia, the granulosa-cell tumor, associated with complex cystic endometrial hyperplasia/pyometra (HECP). The animal was attended in the Animal Reproduction and Veterinary Obstetrics sector of a Teaching Veterinary Hospital with a history of natural breeding, anorexia, emesis, polydipsia, polyuria, and purulent vaginal discharge. During clinical examination, apathy, icterus, swelling of the abdomen, and purulent vaginal discharge were observed. On the ultrasonographic exam, an echogenic content inside the uterus was observed, leading to diagnosis of HECP and an echogenic structure in the abdominal cavity, in ovarian region, confirmed by histopathology as being of granulosa cells. The therapeutic conduct adopted was salpingo-oophorectomy and hysterectomy surgery (OSH).
