Introduction: Giant cell tumour (GCT) in distal ulna is a rare site. GCT is a benign and locally aggressive tumour. Generally occurs in adults between the ages of 20 and 40 years. This is very unusual, with a reported incidence of 0.45 to 3.2%. A few cases of GCT distal ulna have been described in the literature.  Here, we report a case of GCT at unusual site.

Case Presentation: A 17-year-old female presented with a painful swelling of the right wrist with painful wrist movement. That case was diagnosed as GCT of distal ulna after proper investigation. The tumor was treated with marginal resection with chemical cauterization and restoration and fixation of TFCC to distal end of radius with help of ethibond and k-wire, below elbow pop slab was given and K-wire was removed after 6 weeks.

Conclusions: GCT of distal ulna is a rare occurrence. This tumour may have a good prognosis if it is diagnosed early and radically treated. Excision of mass gave us excellent result. Excision biopsy confirmed the diagnosis.
