Exérese de fibrossarcoma em membro torácico direito e reconstrução com enxerto autólogo de espessura completa em cão / Excision of a fibrosarcoma in the right forelimb and reconstruction with full-thickness autologous graft in a dog

Background: Fibrosarcomas are malignant neoplasms originating from fibroblasts that are normally located in the skin, subcutaneous tissue and adjacent to bones. The main treatment for fibrosarcoma is surgery. The removal of large neoplasms from dogs’ limbs usually leads to the formation of large skin defects, often preventing primary occlusion and thus requiring reconstructive surgery to close the wound. This paper reports on the surgical procedure and postoperative complications pursuant to the excision of a fibrosarcoma in the right forelimb and reconstruction with a full-thickness autologous graft in a dog. Case: A 12-year-old Brazilian mastiff presenting a nodule located in the distal segment of the right forelimb, which had grown over a 2-year period, was referred for clinical evaluation. Blood and imaging tests were performed, which showed no changes and excluded the possibility of metastasis. The cytological examination was suggestive of a mesenchymal neoplasm. The patient underwent tumor excision surgery followed by reconstructive surgery with a full-thickness autologous graft to close the defect. The neoplasm was excised by means of a circular geometric figure incision using a 3 cm margin. The defect resulting from removal of the tumor was kept constantly moistened and wrapped in surgical compresses until grafting was performed. The graft was harvested from the region of the right flank based on a surgical field mold taken from the recipient bed. After harvesting the graft, all the subcutaneous tissue was removed until the hair follicles were visible. Fenestrations were then made throughout the entire graft and it was placed in the recipient bed and...

Encefalite parasitária em cadela / Parasitic encephalitis in a bitch

Background: Encephalitis is common in most inflammatory and infectious diseases of the central nervous system, andbacterial and viral pathogens, protozoa, fungi, and erythematous parasites are recognized as etiological agents. Clinicalsigns vary according to the anatomical location and severity of the inflammation. Some parasites may undergo aberrantmigration into the brain of dogs and cats, which is are considered a rare clinical phenomenon. This case report describesthe occurrence of parasitic encephalitis in a mixed breed bitch about 4 year-old.Case: A mixed breed bitch, about 4 year-old, rescued from the street with weakness of the pelvic limbs, was treated at theVeterinary Hospital of the Federal University of Piauí - UFPI. After A clinical and neurological examination, the patientwas hospitalized for diagnosis, treatment, confirmation and follow-up of her clinical evolution. Complementary tests wereperformed to evaluate her general condition, given her unknown history because she was a rescue dog. Complete blood count(CBC), hemoparasite screening, biochemical function (urea, creatinine, ALT, alkaline phosphatase, total protein, albuminand globulin), abdominal and pelvic ultrasound, serological and parasitological tests for leishmaniasis, distemper antigenand ehrlichiosis antibody detection tests were performed, and cerebrospinal fluid (CSF) was collected for analysis. TheCBC revealed normocytic hypochromic anemia and thrombocytopenia. Biochemical functions were within normal limits,except for alanine aminotransferase (ALT), which was slightly low. The ultrasound examination showed splenomegaly.The canine distemper, ehrlichiosis and leishmaniasis tests were negative. The results of the CSF analysis revealed the presence of spherical structures compatible with parasitic cysts, suggestive of Echinococcus granulosus. After the laboratorydiagnosis of parasitic encephalitis, the animal was treated with prednisolone...
