Renal cell carcinoma (RCC) accounts for approximately 3% of all adult malignancies. True gastrointestinal metastases, specifically to gastric wall, have been rarely observed. Herein we describe a case of delayed metastasis to gastric wall occurring more than a decade after previously curative nephrectomy for RCC. A 67-year-old male with history of right radical nephrectomy in 2001 for RCC was f...

We present an unusual case of a metastatic renal cell carcinoma (RCC) mimicking trigeminal schwannoma. The patient, with no prior history of RCC, presented with clinical symptoms and imaging consistent with trigeminal neuralgia secondary to trigeminal schwannoma. Magnetic resonance imaging of the brain showed a large bilobed cystic/solid mass primarily in the cerebellopontine angle cistern, wit...

Renal cell carcinoma (RCC), the fifth leading malignant condition for men and tenth for women, accounts for 3% of all malignancies in Canada. It is a heterogeneous epithelial malignancy with different subtypes and varied tumour biology. Although most cases of RCC are sporadic, up to 4% of patients have an inherited predisposition for the disease. In this article, we review the current molecular...

Over the past decade, our understanding of the biology and pathophysiology of renal cell carcinoma (RCC) has improved significantly. Insight into the disease process has helped us in developing newer therapeutic approaches toward RCC. In this article, we review the various genetic and immune-related mechanisms involved in the pathogenesis and development of this cancer and how that knowledge is...

Renal cell carcinoma has a widespread and unpredictable metastatic potential and it can metastasize virtually to any site,1 even after a very long time from removal of the primary tumor.2 The most common sites for RCC metastasis are lungs, lymph nodes, liver, bones and adrenal glands.2,5 Skeletal muscle metastasis from RCC are extremely rare accounting 0.4% of all RCC metastasis.1e3 A limited n...

Rapid cooling contracture (RCC) was observed in frog toe muscles pretreated with caffeine, chlorpromazine (CPZ), or haloperidol (HPD). During rapid cooling contracture in the presence of caffeine (caffeine-RCC) tension developed to more than 0.8 of the maximum tetanic tension (P0). CPZ inhibited twitch but induced rapid cooling contracture (CPZ-RCC) between 50 and 150 microM; the tension satura...

Clear cell (cc) renal cell carcinoma (RCC) is the most common type of cancer found in the kidney accounting for ~90% of all kidney cancers. In 2012, there were ~337,000 new cases of RCC diagnosed worldwide with an estimated 143,000 deaths, with the highest incidence and mortality in Western countries. Despite improvements in cancer control achieved with VEGF- and mTOR-targeted therapy for RCC, ...

BACKGROUND EGFR and VEGFR2 protein expressions are hallmarks of clear cell renal cancer (RCC) with questionable prognostic impact. The skeletal system is one of the most common metastatic sites of RCC. Unfortunately, there are no data for EGFR and VEGFR2 protein expression in such lesions. MATERIALS AND METHODS Twenty cases of bone metastatic clear cell RCC were analyzed. EGFR and VEGFR2 prot...

Intramedullary spinal cord metastasis (ISCM) from renal cell carcinoma (RCC) is rare manifestation and most of them are treated by adjuvant treatment modalities like radiotherapy. Despite the radio-resistance of RCC itself, focal radiotherapy has been preferred as the first-line treatment modality of ISCM from RCC and only a few cases underwent surgical treatment. We describe a case of ISCM fro...
