Summary
Patellar metastases, rare bone tumors, can be the initial sign of lung cancer. This case highlights a patient whose first lung cancer symptom was a patellar metastasis.
Area of Science:
- Oncology
- Orthopedic Oncology
- Radiology
Background:
- Patellar metastases are exceptionally rare, with limited documented cases.
- Lung carcinoma is an uncommon primary source for bone metastases, particularly in the patella.
- Early detection of metastatic disease is crucial for patient outcomes.
Observation:
- A 33-year smoker presented with patellar metastasis.
- The patellar metastasis was the initial clinical manifestation of lung epidermoid carcinoma.
- Literature review identified only a few prior reports of patellar metastasis from lung cancer.
Findings:
- This case adds to the scarce literature on patellar metastases.
- It underscores the possibility of lung cancer presenting initially as a patellar lesion.
- The patient's smoking history is a significant risk factor for lung cancer.
Implications:
- Increased awareness of rare metastatic sites like the patella is necessary for clinicians.
- Consideration of lung malignancy in patients with unexplained patellar lesions, especially those with risk factors.
- Further research into the patterns and mechanisms of rare bone metastases is warranted.
