Background: Malignant peripheral nerve sheath tumors are neurogenic neoplasms that originate from cells that surroundthe axons of peripheral nerves. Surgery is the treatment of choice for peripheral nerve sheath tumors. They have a betterprognosis when the lesion is in the extremity of a limb and the surgeon leaves wide peripheral margins after resection.However, this procedure makes local treatment a challenge due to difficult wound healing in this region. This report describes a successful case involving the use of a meshed skin graft immediately after resection of a neurofibrosarcoma inthe distal region of the radius bone of a dog.Case: A 6-year-old Boxer bitch weighing 40 kg was admitted with a history of a round, firm, non-ulcerated skin noduleattached to the lateral side of the distal region of the right radius bone, which had been present for about 40 days. Fineneedle aspiration cytology of the lesion showed the presence of mesenchymal cells, suggesting a sarcoma. Thus, the decision was made for an incisional biopsy to confirm the diagnosis and for the preparation of a subdermal pattern tubular flapfor subsequent rotation and transposition to close the wound that would be formed after the complete removal of the lesion.After the 7th postoperative day, the diagnosis of low-grade neurofibrosarcoma was confirmed and due to the presence ofnecrotic onset in the middle portion of the tubular flap, further surgical intervention was scheduled for the resection of thetube flap, en bloc removal of the neoplastic lesion with peripheral margins of 2 cm, and wound closure with a free skingraft. A mesh skin graft was made with a portion of the right flank skin. The mesh graft was carefully implanted on therecipient bed using simple interrupted sutures with a 3-0 non-absorbable monofilament suture material. A dressing madewith water-based sterile lubricating solution and...(AU)
