Introduction
Adamantinoma is a very rare, low-grade, malignant bone tumour that accounts for approximately 0.4% of all primary bone tumours. Radiographically, adamantinomas vary in length, have a clearly defined outline, with a bubbly appearance and increase the width of the bone. Histologically, epithelial cells, endothelial cells synovial cells have been implicated as cells of origin.
Case presentation
We present a case of adamantinoma of the tibia, in which a resection of the whole tibia and reconstruction with a total tibia allograft was necessary.
Discussion
The histological diagnosis is sophisticated. It is often difficult to distinguish an adamantinoma from other tumours. The most frequent described method to treat adamantinoma is wide resection and the use of an allograft. The most common complication is fracture presented similarly in our patient.
Conclusion
A total tibia allograft as presented in our case is not described in the literature. It fractured due the first year after implantation. Using a prosthesis system instead of the allograft might have saved the limb of our patient.
