AIMS/BACKGROUND: Giant cell tumour of the tendon sheath (GCTTS) is regarded as the most common neoplasm of the hand that can recur after excision. The objective of this study was to review a series of cases in our department and to determine any clinical or pathological features that might predict the likelihood of recurrence. METHODS: Clinical data, obtained from pathology request forms and in patient notes, along with the gross and microscopic appearances of 71 cases of GCTTS were evaluated. RESULTS: Clinical features and pathological features identified were similar to those of previous studies. In comparison with previous studies a higher mitotic count (range, 1-21 mitoses/10 high power fields (HPF); mean, 5/10 HPF) was noted in all cases, irrespective of recurrence and numerous apoptotic bodies (up to 30/10 HPF), mainly formed from osteoclast-like giant cells, were present. CONCLUSIONS: GCTTS is a relatively rare soft tissue tumour of uncertain histiogenesis. Mitotic and apoptotic figures are a common feature and do not indicate clinical behaviour. Complete local excision is the treatment of choice.

A 21-year-old Arab gelding with clinical signs of acute peritonitis had a perforating ulcer on the mesenteric border of the jejunum which resulted in localised contamination of the abdomen with ingesta. The affected segment of jejunum was resected and the abdomen was lavaged extensively. Postoperatively, the gelding was treated with broad-spectrum antibiotics, non-steroidal anti-inflammatory drugs and intravenous fluids, but after four days it became acutely non-weight bearing on its right hindlimb, and a tendonitis of the lateral digital flexor tendon within the tarsal sheath was identified ultrasonographically. The septic tendonitis was treated with broad-spectrum antibiotics but progressed proximodistally within the tendon until it involved both the tarsal sheath and the associated tarsocrural joint, necessitating the euthanasia of the gelding.
