“…The clinical presentation of malignant AV shunting caused by osseous metastasis is not well described in the literature, but has been reported as pulsatile tumours in the sternum15 and proximal tibia 16. Howlett and Caranasos13 reported a case of RCC secondaries in the patella and iliac bones generating extensive AV shunting and lower limb ischaemia. Osseous RCC metastasis presenting as deep venous thrombosis has also been described 17…”

Renal cell carcinoma is reported to have potent angiogenic activity with a high microvascular density in both primary and metastatic sites compared with other adenocarcinomas. Angiogenesis can lead to the formation of abnormal arteriovenous shunts that can, in patients with peripheral vascular disease, result in worsening of the degree of ischaemia by producing a vascular steal-like phenomena. Nevertheless, steal phenomena secondary to malignancies are extremely rare. We report a case of distal critical limb ischaemia in a patient with peripheral vascular disease exacerbated by massive arteriovenous shunting due to tibial metastases from renal cell carcinoma.

“…Metastatic sites in the extremities can cause reversal of blood flow and distal ischaemia [2]. AV fistulas from RCC are almost exclusively found in bone [3,4], despite the fact that the lung is a more common site of metastatic disease. This may be due to a microenvironment within bone that is particularly supportive of angiogenesis.…”

Arteriovenous (AV) fistulas are common in renal cell carcinoma. These are usually small and asymptomatic. Case reports have previously described symptomatic fistulas in primary renal cell tumour or, less commonly, bone metastases.The current study describes a patient with lung metastases from renal cell carcinoma who developed a symptomatic pulmonary AV fistula. The patient presented with debilitating progressive shortness of breath, which resolved after coiling of the pulmonary AV fistula. Supporting radiographs include a unique ventilation-perfusion finding of perfusion tracer in the kidney that is diagnostic of a pulmonary shunt. This is the first report of a pulmonary fistula from renal cell carcinoma. This rare complication of renal cell carcinoma reflects its diverse clinical presentations and unique tumour biology.

“…On occasion, soft blue cartilage was indicative of the pathological change. The radiographs of the chest, bronchoscope and thoracic multi-slice computed tomography were necessary for diagnosis of the primary lesion, since it was possible to easily identify a mass in the lobe (6,13,22,25). Excision biopsy was performed and the diagnosis was confirmed using pathological testing.…”

Abstract. Although bone tumors are frequently located in the knee area, primary tumors of the patella are rare and patellar metastases are even rarer. Knee pain is the most common complaint of patients with patellar metastases. Owing to the low incidence of patellar metastases, misdiagnosis is not unusual. The present review analyzes ~44 cases of patellar metastases originating from distinct primary sites. Reports of malignant tumors of the lung and kidney metastasizing to the patella were more common than those of other patellar metastases. Relative incidence, symptomatology, imaging features, histopathology and treatment options for these patellar metastatic lesions are described respectively along with a review of the literature. Despite numerous experiments demonstrating the reasons for implantation of tumor in patella, the answer to this question has not yet been revealed. In the light of the increasing attention on the diagnosis and the treatment of these lesions, the availability of the integrated information regarding metastases in the patella becomes more relevant.
