Introduction:
Enchondroma is a cartilaginous benign tumor of bone with the most common involvement of tubular bones of hands and feet. The triquetrum and pisiform are carpal bones and the enchondroma of the triquetrum and pisiform has not been reported in the literature to the best of our knowledge.
Case Report:
A 26-year-old male presented with swelling over his right wrist with painful terminal motion. Based on magnetic resonance imaging findings, diagnosis of enchondroma of triquetrum and pisiform was made. Bone excision and curettage were performed, and histopathology confirmed the diagnosis. After 2 years of follow-up, the patient has gained pain-free wrist movements post excision, and there are no signs of recurrence. The Modified Mayo Wrist Score of 75 (fair) improved to 100 (excellent).
Conclusion:
The surgeon should always keep in mind the possibility of a tumor at the rare site and accurately diagnose the tumor with the help of imaging modalities and biopsy.
