Introduction:
Giant cell tumor of the tendon sheath (GCTTS) is a benign tumor, originating from proliferation of the synovial cells of a tendon sheath. It is very rare within the pediatric population.
Case report:
In this case presentation, we describe two cases of GCTTS in the hand, in a 7-year-old female and a 6-year-old male.
Conclusion:
GCTTS occurs very uncommonly in children. It is difficult to accurately diagnose on clinical examination and radiological investigation alone, and thorough and complete excision is important to avoid recurrence of the lesion. The two cases presented in this report help further define this condition, in terms of diagnosis and management, in the pediatric population.
