Aneurysmal cyst of the thumb in young adults: about an exceptional case

The aneurysmal bone cyst is a benign, locally aggressive tumour. It affects children and young adults with a preference for the long bones and the vertebrae, rarely the hand. Involvement of the thumb is exceptional, the author reports an observation in a young 18-year-old patient, complaining of a painful swelling of the right thumb. The positive diagnosis is evoked on radiography, confirmed by the histology after surgical biopsy. Radical excision was opted for our patient, who, unlike conservative treatments, seems to avoid recurrence.
