Resumo
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...(AU)
