Highlights The distal Ulna is an unusual site (0.45%–3.2%) for a primary bone GCT. The functional reconstruction of the defect after resection has been a challenge. Many surgeons try to retain the ulna and perform the only curettage and packing with polymethylmethacrylate. Unfortunately, there is a high recurrence rate of up to 40% when treated in such a manner. Wide resection of the distal ulna with or without reconstruction or stabilization of the ulnar stump is the recommended treatment for GCTs in such locations. We present two patients with GCT of the distal ulna, all of them treated by wide resection of the distal ulna followed by stabilization of the remaining ulna using one half of the extensor carpi ulnaris (ECU) tendon. All the patient satisfied with the treatment.

BACKGROUND: Gout is a condition characterized by abnormally elevated levels of uric crystals (gouty tophi). It is often to detect in the foot and ankle. Occasionally such tophus is found at rare sites and makes a challenge to the clinician where diagnosis and treatment are concerned. CASE REPORT: We present a patient who presented to our oncology department with pain on her right hip. It was diagnosed as a benign tumor by the clinical and radiological assessment but intraoperatively turned out to be gouty tophi. Excision surgery has performed, in the 1-year follow-up; there is no relapse of pain. CONCLUSIONS: Tophaceous gout in the hip joint is a rare case, which clinical and radiology assessments can detect erroneous diagnose. Tophaceous gout in the hip joint mimicked the bone tumor characteristics. It requires a better application and diagnosed for the mimicked tophaceous gout.
