Abstract:
Clinical, epidemiological and pathological aspects of equine sarcoid diagnosed at the the Laboratory of Animal Pathology of the UFCG. Describes the frequency of equine sarcoid diagnosed in horses through retrospective study
of biopsies performed by the Animal Pathology Laboratory of the Federal University of
Campina Grande (LPA-UFCG) during the period from January 2003 to August 2014 forms
were analyzed clinical, epidemiological and histopathological aspects. The definitive
diagnosis was made by the macroscopic findings and histopathology. During the period
were diagnosed 33 cases of equine sarcoid, and of these, 25 were on horses, donkeys and 7
in 1 in mule. There was no significant difference between the sexes of animals and the
most commonly affected age group was between 1-5 years old with 75.76% (25/33) of
cases. The most affected animals were mongrel, totaling 22 cases. Most tumors were
present in the head (33.93%) and members (19.64%), and were mostly sarcoid-type
fibroblast 46.47% (26/56). The verrucous sarcoid is constantly reported as often noted in
12 cases. It is suggested that the anatomic predilection tumor is related to areas more prone
to trauma and where the animal can not discount the vectors of the site. Histologically the
proliferation of fibroblasts in the superficial and deep dermis and the presence of pseudo-
epitelimatosa epidermal hyperplasia were the most common findings. Many cases had
secondary infection and in three cases there was an association of equine sarcoid with
habronemose. With this study it is shown that the equine sarcoid is a neoplasm often
diagnosed in horses in northeastern Brazil, and further studies in this area are carried out to
better understand the causal behavior that this tumor has.
