A 4 year-old gelding Quarter horse was presented for evaluation of an incompletely healed wound. Three weeks previously the horse had sustained several skin lacerations while in the pasture. Topical ointment had been applied. The wound on the medial aspect of the left tarsus was forming a small walnut-sized granulation tissue mass. Associated with this was mild generalized soft tissue swelling. The horse was not currently lame and lameness had not been noted initially. A second wound on the right lateral metacarpus was healed. Radiographs of the tarsus were taken.
