Objective: Here we describe a case of an ABC of the trapezium that, to our knowledge, has been mentioned in the literature only twice.
Case description: We describe the case of a solid variant of juxtacortical aneurysmatic bone cyst affecting the trapezium in a 38-year-old healthy male patient complaining about pain and reduction of range of motion. The excision, after completion of diagnostic workup with advanced imaging (CT scan and MRI), led to complete regression of symptoms within two weeks and a recurrence free period of five years.
Conclusion: Aneurysmatic bone cysts are rare, benign bone tumors representing 2% of all bone tumors. Only 3-5% of cases occur in the hand, the carpal bones being the least affected. The knowledge of this rare tumor is important to properly address treatment and postoperative care.
