Testicular metastasis from renal cell carcinoma is very rare. Herein we report a case of left-side renal cell carcinoma initially diagnosed to be clinically stage II, which developed left-side testicular metastases 2 months following radical nephrectomy. High inguinal orchiectomy was carried out. The patient was asymptomatic 2 months later. Although renal vein involvement in renal cell carcinom...

BACKGROUND Vascular endothelial growth factor (VEGF) protein plays important role in renal cell carcinoma (RCC) development and progression. VEGF gene polymorphisms can alter the protein concentrations and might be associated with renal cell carcinoma risk. However, the results of studies investigating the association between VEGF polymorphisms and renal cell carcinoma risk are inconsistent. Th...

PURPOSE Localized renal cell carcinoma is usually curable by nephrectomy. However, a large fraction of patients already present with metastatic disease, which results in a poor outcome. Currently no clinically relevant screening assay is available to detect early stage renal cell carcinoma. We investigated whether urinary extracellular matrix (ECM) proteins and/or matrix metalloproteinase (MMP)...

OBJECTIVES To report a new case of late renal cell carcinoma recurrence. METHODS Renal cell carcinoma represents approximately 3% of all adult malignancies. The most frequent metastatic sites are lung (76%), regional lymph nodes (66%), bone (42%), and liver (41%), and it is the third most common infraclavicular neoplasm to metastasize to head and neck. RESULTS 73 year-old man with a 1 week ...

Renal cell carcinoma is the most common renal tumor in adults. Clear cell carcinoma represents 85% of all histological subtypes. In February 2012 a 72-year-old woman came to our department due to the appearance of massive hemoptysis and pharyngodinia. Previously, this patient was diagnosed with a renal cell carcinoma treated with left nephrectomy. We observed an exophytic, grayish, and ulcerate...

BACKGROUND Renal cell carcinoma is associated with a wide spectrum of para-neoplastic syndromes, which may be precursors of primary or recurrent disease. Non-metastatic hepatic dysfunction in patients suffering from renal cell carcinoma is known as Stauffer's syndrome. It is associated with the production of cytokines by the tumour, and several biochemical abnormalities, including elevated seru...

Diverse chemokines and their receptors have been associated with tumor growth, tumor dissemination, and local immune escape. In different tumor entities, the level of chemokine receptor CXCR4 expression has been linked with tumor progression and decreased survival. The aim of this study was to evaluate the influence of CXCR4 expression on the progression of human renal cell carcinoma. CXCR4 exp...

BACKGROUND Renal cell carcinoma developing metastases in the bladder is rare. Bladder metastasis due to a papillary type of renal cell carcinoma is rarer. Such metastases could be synchronous or metachronous. CASE PRESENTATION Here we present a 55-year-old female patient with haematuria who underwent left nephro-ureterectomy for a suspected urothelial tumour. Histopathology revealed it to be ...

A 49-year-old lady presented with multiple recurring painful lesions over her thighs, arms, and back. Past medical history included a left sided nephrectomy for renal cell carcinoma and a hysterectomy for multiple uterine fibroids (leiomyomas). Histopathological examination revealed changes consistent with pilar leiomyomas. Gene mutation analysis confirmed a diagnosis of hereditary leiomyomatos...
