Sarcoide em equinos - tratamento com associação de Aciclovir e excisão cirúrgica / Equine sarcoids - treatment with a combination of Acyclovir and surgical excision

Background: Sarcoids are the most frequent skin tumors among horses, causing serious lesions due to their different shapes, sizes, degree of invasiveness and distribution on the body. The pathogenesis of sarcoids is multifactorial, with genetic, viral and environmental involvement, making their treatment complex. The aggressiveness and high rate of recurrence of sarcoids makes it difficult to use an effective treatment, which is why there are several therapeutic routes described in the literature. Aiming to describe and expand sarcoid treatments, this paper reports on the use of acyclovir in the treatment of this type of tumor. Cases: Four horses sent to the Large Animal Veterinary Hospital of the Federal University of Lavras - UFLA were diagnosed and treated for sarcoids. Case 1. Lesions on the right ear, region of the masseter muscle of the right side of the face, neck, vulva and medial aspect of the left pelvic limb. Case 2. Lesion in the left groin region. Case 3. Lesions on the face, masseter muscle region on the left side, mandibular region and right ear pinna. Case 4. Lesion in the lateral region of the left pelvic limb, close to the tarsometatarsal joint. All horses had a diagnosis of sarcoid, which was confirmed by histopathological examination of material collected after surgical excision. Macroscopically, the neoplastic lesions were classified as fibroblastic, verrucous and nodular. The tumors exhibited irregular surfaces, keratinization, and a firm consistency. Their surfaces were alopecic, slightly rough, some of them were ulcerated, and their color ranged from greyish to rosy and reddish. All the tumor masses were surgically excised from the 4 horses, and one sarcoid was treated by thermal cauterization with liquid nitrogen due to the lesion's depth and size. In most cases, the sarcoid removal sites were closed with sutures. Only 2 lesions were not sutured due to the impossibility of bringing the edges of tissue close together, or due to proximity to the tarsometatarsal joint. The surgical wounds were cleaned twice a day with sterile saline solution followed by the topical application of Acyclovir. One of the animals received complementary therapy with Cimetidine. Discussion: The equines recovered completely from their sarcoid treatment, and no recurrences were reported a year later. Thus, the combination of treatments employed for the extirpation of sarcoids proved to have greater chances of success. First, all the tumors were surgically removed with the largest possible margins of safety in order to ensure the elimination of neoplastic cells. In the postoperative period, all the animals received topical treatment of the lesions with acyclovir after surgical resection of the tumors. The drug aided the complete healing of post-surgical wounds, and healing time varied according to the size and depth of the lesion. One tumor was treated with liquid nitrogen after surgical excision of the sarcoid. Another horse was treated with cimetidine over a 3-month period after surgical excision of the neoplasm in order to reduce the sarcoid and prevent its evolution. Surgical excision of the sarcoid associated with topical application of acyclovir ointment showed satisfactory results. Moreover, the combination of surgical excision and administration of liquid nitrogen on the lesion and topical application of acyclovir ointment in the postoperative period also provided good results. Given the complexity of sarcoid treatment and the high recurrence rate of these tumors, the use of combined treatments should be taken into account.

Penectomia parcial em equino com sarcoide de glande / Partial equine penectomy withglans sarcoid / Penectomía parcial en equino con sarcoide de glande

O sarcoide é a neoplasia cutânea mais frequente em equinos, independentemente da raça e coloração da pelagem. Há evidências consideráveis que o fator mais importante da oncogênese do sarcoide equino é a infecção pelo papilomavírus bovino (BPV) tipo 1 e 2, sendo o contato direto de equinos com bovinos a rota mais comum de transmissão. É uma neoplasia localmente invasiva e não metastática, clinicamente parecida com outras doenças, como carcinoma de células escamosas e habronemose, sendo o diagnóstico definitivo realizado através da biópsia e exame histopatológico. O prognóstico depende do lugar e do tipo de tratamentoe, em muitos casos, a excisão cirúrgica é a única opção viável para o tratamento do sarcoide. Um equino, macho, não castrado, da raça Crioula, de cinco anos de idade e 410 kg de peso, foi atendido no Setor de Grandes Animais do Hospital de Clínicas Veterinárias da UFRGS, apresentando aumento de volume na região da glande, com aspecto nodular e presença de miíase. O diagnóstico do sarcoide foi realizado através do exame histopatológico e o animal foi submetido a cirurgia de penectomia parcial, onde a neoplasia pôde ser retirada completamente. Descreveu-se a técnica cirúrgica utilizada e acompanhou-se o pós-cirúrgico do paciente, o qual não apresentou complicações e pôde retornar à suas atividades em um curto período de tempo.

The sarcoid is the most common cutaneous neoplasm in horses, no matter the breed and coat coloring. There are considerable evidence that the most important facto r in equine sarcoid oncogenesis is the bovine papillomavirus infection (BPI). type 1 and 2, in which the direct contact of horses with cattle the most common route of transmission. It is a locally invasive and non-metastatic neoplasm, clinically similar with other diseases, such as squamous cell carcinoma and habronema. with the definitive diagnosis being made through the biopsy and histopathological examination. The prognosis depends on the place and the kind of treatment and, in many cases, a surgical excision is the only viable option for the treatment of sarcoid. A horse, male, non-castrated, Criollo breed, five years old and weighting 410 kg, was attended at the Large Animais Sector of the Hospital of Veterinary Clinics of UFRGS, presenting an increase in volume in the glans region, with nodular appearance and presence of myiasis. The diagnosis of the sarcoid was made through histopathological examination, and the animal underwent partial penectomy surgery, where the neoplasm could be completely removed. The surgical technique was described and the patient's postoperative period was followed, which presented no complications and was able to return to its activities in a short period of time.

Sarcoid associated with infection by Habronema spp. in equines in Brazil / Sarcoide associado à infecção por Habronema spp. em equinos no Brasil

Background: Equine sarcoid, supposed to be caused by infection with bovine papillomavirus type 1 or 2, is usually observed in previously traumatized skin areas, including lesions of habronemosis due to inoculation of third stage larvae in ulcerated wounds by Musca domestica or Stomoxys calcitrans. Little is known about the occurrence of diseases associated with equine sarcoid, mainly because limitations on clinical diagnosis, due to the different skin diseases that have to be considered as differential diagnoses. This report aimed to describe three cases of equine sarcoid associated with habronemosis in horses in the semiarid region of Northeastern Brazil. Cases: Three cases of sarcoid associated with habronemosis in equines were diagnosed at the Animal Pathology Laboratory of the Veterinary Hospital of the Federal University of Campina Grande, Patos, Paraíba. Case 1. A 5-year-old female showed in the ventral branch of the mandible a nodule of 3 cm in diameter, partially covered with skin and hair intercepted by areas of irregular surface with yellow-red ulcerations.

Bovine papillomavirus type 13 DNA in equine sarcoids.

Equine sarcoids are locally aggressive fibroblastic neoplasms considered to be the most common skin tumors of horses worldwide. Bovine papillomavirus types 1 and 2 have typically been associated with sarcoids in equids. Investigations aiming to identify papillomavirus strains, aside from bovine papillomaviruses 1 and 2, which might be associated with sarcoid lesions, have been lacking. The aim of this article is to report the identification of a third bovine papillomavirus type, bovine papillomavirus 13, associated with equine sarcoids. Six sarcoid lesions were collected from diverse anatomical sites on two horses from southern Brazil. To detect a broad spectrum of papillomavirus strains, eight degenerate primer pairs designed to detect conserved regions on the L1 and E1 genes were tested on the DNA samples. Direct sequencing was then performed on the obtained amplicons, and sequence identities were compared with sequences from all bovine papillomavirus types. The FAP59/FAP64, MY09/MY11, and AR-E1F2/AR-E1R4 sequences generated from the sarcoids were shown to present 99 to 100% identity with bovine papillomavirus 13, a new bovine papillomavirus type previously described in cattle. The results from this study suggest that there is a need to identify bovine papillomavirus type 13 and other papillomavirus strains that might be associated with sarcoids in diverse geographical areas; such investigations might establish the frequency of occurrence of this viral type in these common tumors of equids.

Mycobacterium DNA detection in liver and skin of a horse with generalized sarcoidosis.

Sarcoidosis is a rare equine skin disease characterized primarily by an exfoliative and granulomatous dermatitis but also presenting granulomatous inflammation of multiple systems. The current report presents the clinical and histopathological findings of sarcoidosis in a 16-year-old American Quarter Horse gelding with nested polymerase chain reaction Mycobacterium spp. DNA detection within hepatic and skin samples. Mycobacterium spp. may play a role in the pathogenesis of equine sarcoidosis as has been proposed for human sarcoidosis.

Co-infection of Bovine Papillomavirus and feline-associated Papillomavirus in bovine cutaneous warts.

The diversity of papillomavirus (PV) found in bovine cutaneous warts from Brazilian cattle was evaluated using the PCR technique with the utilization of consensus primers MY09/11 and by PCR using Bovine Papillomavirus (BPV) type-specific primers followed by sequencing. Eleven cutaneous warts from 6 cattle herds were selected. Six warts were positive for the presence of PV. The presence of BPV types 1, 2, 3, 6 and feline sarcoid-associated PV (FeSarPV) in cutaneous wart lesions, as well as the presence of co-infections, was found. To the best of our knowledge, this is the first time that FeSarPV is described co-infecting a cutaneous wart in Brazil. The present study confirms the previous finding of FeSarPV infecting cattle. These results show the necessity of more studies to investigate the diversity of PV in cattle, its diversity and the possibility of co-infection in cattle and other animals.

Aspectos epidemiológicos e distribuição anatômica das diferentes formas clínicas do sarcoide equino no Rio Grande do Sul: 40 casos / Epidemiological aspects and anatomic distribuition of equine sarcoid in the state of Rio Grande do Sul, Brazil: 40 cases

The files of histopathological exams carried out by the Laboratório de Patologia Veterinária of the Universidade Federal de Santa Maria (LPV-UFSM), between January 2000 and March 2010, were reviewed in search of cases of equine sarcoid. Forty cases were selected to determine epidemiological aspects and anatomical distribution of the various clinical forms of these neoplasms in horses from Rio Grande do Sul. Out of the cases in which the ages were registered in the histopathological reports, 73.0 percent (27/37) were 1 to 5-year-old horses. Multiple sarcoids were observed in most of the affected horses (29/40 [72.5 percent]). The fibroblastic form was most frequently observed and occurred in 42.2 percent (27/64) of the cases. In more than half of the cases (22/40 [55.0 percent]), sarcoids had a multifocal distribution. Twenty two (55 percent) out of the 40 horses evaluated had the tumors in the limbs.
