title: Tophaceous gout of the patella: a report of two cases.
abstract: Introduction. Tophaceous gout of the patella is rare and may masquerade as a tumour or tumour-like condition. Cases. We report two patients with gout involving the patella, one complicated by a pathological fracture and the other occurring in a bipartite patella in a young adult. Discussion. Typical imaging appearances and measurement of serum urate will usually confirm the diagnosis but, occasionally, the serum urate level may be normal in active gout and in such cases, a biopsy will be required. Conclusion. Gout of the patella may masquerade as a tumour or tumour-like condition and it is important to consider gout in the differential diagnosis.
