Background
Aneurysmal bone cyst (ABC) secondary to Giant Cell Tumor of bone (GCT) is a rare lesion, of which the incidence is about 0.011 to 0.053 per 100,000 every year. There are only a few previous case reports, and most of them occur in the spine, long bones or flat bones.
Case presentation
We report one case of a patient who complained of “progressive enlargement of the mass on right-hand fifth finger for 5 years with ulceration for 6 months”. After the imaging examination in our hospital, it was diagnosed as a “huge bone tumor on the proximal phalanx of the right-hand fifth finger”, then wide excision and amputation of the fifth finger were made. The pathological examination diagnosed the mass as aneurysmal bone cyst secondary to giant cell tumor, 13 × 8 × 6 cm3, with no local infiltration observed. No recurrence and metastasis occurred 18 months after the operation, and the patient recovered well.
Conclusion
In this report, we discuss the etiology, diagnosis, differentiation, and management of Aneurysmal bone Cyst secondary to Giant Cell Tumor of bone, and review previous case studies.
