Resumo:
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.
