Large fibrosarcoma of the equine distal limb treated by surgical excision using a harmonic scalpel

An 18-year-old Warmblood gelding was presented for investigation of a large, firm mass over the medial and plantar aspect left distal metatarsal fetlock region. The first identified 4 months prior to referral, following traumatic incident, had time gradually increased in size. Clinical examination diagnostic imaging revealed large soft tissue adjacent metatarsophalangeal joint digital flexor tendon sheath, with no overt involvement underlying bone. surgically excised under general anaesthesia using harmonic scalpel limited margins avoid compromise anatomical structures. Following histology, diagnosed as fibrosarcoma. Twelve after surgical resection, signs recurrence were evident. This report demonstrates that fibrosarcoma equine limb may be successfully managed excision. use should considered an alternative sharp excision when treating or other infiltrative tumours, particularly those located regions where only achieved.
