The treatment of lower extremity defects with severe proliferative tissue using an adjustable horizontal mattress suture in a Tosa dog

A 2-year-old male Tosa was admitted for treatment of a non-healing wound on the right forelimb. Skin tests were unremarkable; however, the lesion contained severe proliferative tissue. Surgical treatment was conducted due to the extensive skin defect and granulation tissue present. Following removal of the proliferative tissue, the wound was closed using the adjustable horizontal mattress suture method with multiple punctate relaxing incisions. The proliferative tissue healed completely after the surgical treatment. This technique can be considered an alternative treatment for the proliferative tissue when conditions require a skin graft or flap after surgical treatment.
