Introduction:
This case report describes the third documented example of primary esophageal carcinoma metastasizing to the patella and the first documented example of esophageal carcinoma metastasizing to synovium.
Case Report:
A 67-year-old man with a history of metastatic esophageal carcinoma presents with right knee pain and an aggressive, destructive lesion involving the superior patella. Biopsy revealed esophageal carcinoma. After ineffective radiation, he underwent resection of the tumor-filled bone and quadricep advancement. Two months later, a recurrent tumor involving the entire patella and significant knee synovitis was observed. He underwent a total patellectomy with a radical anterior synovectomy. Further assessment showed that the entire synovium was replaced with metastatic carcinoma.
Conclusion:
This report describes an atypical presentation of metastasis with patella and synovium involvement.
