Adenomiose uterina em gata associada à piometra / Uterine adenomyosis in a queen associated to pyometra

Adenomyosis, a non-neoplastic myometrial proliferation, is a rare pathologic condition in domestic animals, of unknown etiology. There is a lack of information about the clinical and pathological features of this disease in cats, therefore just a few reports in that species. The study describes a case of adenomyosis in a feline female. A cat, six years old, undefined breed, not spayed, had abdominal swelling history and vaginal discharge. Clinically, upon abdominal palpation, a diffuse increase suggesting a uterine change was found. The vulva had sanguine-purulent exudates. The choice was for the neutering surgical. Uterine macroscopy revealed cystic endometrial hyperplasia/pyometra in uterine horns, and the presence of a diffuse mass on uterine corpus. Fragments of the mass were sent for histopathological analysis, which revealed adenomyosis of the uterine corpus. The patient exhibited adequate post-operative recovery. The adenomyosis should be considered as a differential diagnosis of uterine neoformation in domestic cats.(AU)

Patología uterina y su impacto en la fertilidad / Impact of uterine diseases on fertility

El útero es un órgano fundamental dentro del proceso reproductivo y participa en eventos claves, como el transporte espermático, la implantación y la nutrición fetal. Los miomas uterinos, las anomalías congénitas, los pólipos endometriales y las sinequias uterinas son las principales patologías uterinas en mujeres en edad reproductiva, y pueden ser causa de infertilidad, aborto recurrente o parto prematuro. De acuerdo a la evidencia, el tratamiento quirúrgico de miomas uterinos submucosos e intramurales (que distorsionan la cavidad uterina), pólipos endometriales y sinequias se asocia a un aumento significativo en las tasas de embarazo. El tratamiento quirúrgico del septum uterino disminuye significativamente la probabilidad de aborto a repetición y puede incrementar la probabilidad de embarazo en pacientes sin otra causa aparente de infertilidad. El tratamiento quirúrgico de miomas intramurales y subserosos (que no comprometen la cavidad endometrial) es controvertido y su indicación depende de la evaluación de cada caso en particular.

The uterus exerts an important role in the reproductive process and participates in key events, including sperm migration, embryo implantation and fetal nourishment. Uterine myomas, congenital anomalies, endometrial polyps and uterine synechia are the main diseases affecting women in reproductive age, and display a significant impact as asource of infertility, recurrent abortion or preterm labour. According to evidence, surgical treatment of submucous and intramural myomas (associated to uterine cavity distortion), endometrial polyps and uterine adhesions significantly improves pregnancy rates. Surgical treatment of uterine septum significantly decreases recurrent miscarriage rate and can increase odds of pregnancy in patients with no apparent cause of infertility. Surgical treatment in patients with intramural and subserous myomas (without endometrial cavity distortion) is controversial and treatment should be based on an individual basis.
