Solitary Metastasis of the Patella in the Differential Diagnosis of Anterior Knee Pain
INTRODUCTION
The patella is a sesamoid bone and, because of poor vascular
supply, it is considered that metastases are not usual (1).
Only about 30 cases of patellar metastasis originating from
different primary tumours, mostly lung and breast have been
reported in the literature (2β15). In only eight cases was
patellar metastasis the only sign of distant tumour (16β20).
Here, we present a unique case of patellar metastasis of
lung adenosquamous carcinoma, with the anterior knee pain
as the first and only sign of the disease
