Giant cell tumour of EHL tendon sheath in young: a rare case report and review of the literature.

Giant cell tumour of tendon sheath also known as benign synovioma is a slow-growing benign tumour originating from tendon sheath, ligaments or bursa. We present a case of swelling over the left foot of 7-month duration in 11-year-old boy diagnosed as giant cell tumour of tendon sheath. There was an extensive pressure effect of tumour mass on the second metatarsal evident by scalloping. Local excision was planned and executed, and reduction in scalloping was evident at 26-month follow-up with no recurrence. We conclude that en bloc resection of tumour with a hydrogen peroxide lavage may result in a favourable prognosis without recurrence.
