Hiperplasia prostática benigna em um cão com quatro anos e identificação de Leishmania sp. na próstata de cães.

Abstract

The objective of these studies were to report an occurrence of benign prostatic hyperplasia in a young dog with advanced clinical signs, unusual for the age group and the identification of Leishmania sp. in the prostate of dogs by the techniques of cytology, immunohistochemistry (IHq) and histopathology and to show the effectiveness of each one. In the chapter I, a canine, dachshund, male, four-year-old was reported at the Veterinary Hospital (VH) of the Federal University of Campina Grande (FUCG), with a volume increase in the perineal region for 15 days, tenesmus and episodes of soft stools. On physical examination, there was an increase in volume in the left dorsal perineal region. Abdominal ultrasound examination revealed a discrete heterogeneous echotexture, measuring 3.76 x 3.75 cm², herniated content with a hypoechoic and echogenic aspect in the perineal region. After the diagnosis of perineal hernia secondary to a BPH, the animal was referred to the surgery department where the surgical correction of the hernia and the orchiectomy of the dog were done. The animal was followed up for two months after surgery, where it was confirmed the reduction of the initial volume of the prostate through the ultrasound, thus successful in the treatment of this type of prostatopathy. Although BPH is a common disorder in elderly dogs, the clinician should not investigate this condition when a patient has tenesmus and/or cystitis even though they do not belong to the risk age group. For chapter II, 25 male dogs, with no predilection for breed, previously diagnosed with Leishmaniosis, were treated at the Small Animals Medical Clinic of the FUCG VH. After euthanasia, fine-needle aspiration (FNA) of the prostate was performed and fragments of the prostate were collected for imprinting and for IHq examination. In cytology, the presence of amastigote forms was observed in 56% of prostate samples. From this total was observed positivity in 100% blades made by FNAB and in 4% by imprint. The IHq of the 25 samples analyzed, 4% showed positive immuno-marking, as well as in the base blades made stained with HE. It was concluded that the reproductive apparatus of dogs can be a reservoir for infecting forms, evidencing the epidemiological importance of this finding, in the association of programs to eliminate the vector as the only method of controlling this pathology.
