A sarcomatoid component can occur in all histologic subtypes of renal cell carcinoma (RCC) and indicates an aggressive tumor. It is reported in literature that the sarcomatoid component can resemble fibrosarcoma, malignant fibrous histiocytoma or rhabdomyosarcoma. We describe the case of a 59-years old patient diagnosed with a chromophobe renal cell carcinoma, presenting a very rare osteosarcom...

Renal tumors are the third most common malignancies after prostate and bladder cancers amongst the urologic neoplasms [1]. Renal cell carcinomas (RCCs) account for 85% of all renal epithelial tumors. Clear cell is the most common subtype of RCC, papillary and chromophobe subtypes are the other common histologic subtypes. Here in, we report a case of papillary RCC presenting with hematuria which...

Asians differ from Caucasians as photoageing tends to present with pigmentary changes as the main issue. Furthermore, with a higher epidermal melanin context, there is a greater risk of complications especially postinflammatory hyperpigmentation and such high epidermal melanin context also acts as a competing chromophobe for the underlying target. In this review article, recent advances in the ...

Renal cell carcinoma associated with fused ectopic kidneys has rarely been reported in the literature. Here we report the first case of robot-assisted heminephrectomy for chromophobe renal cell carcinoma in an L-shaped fused ectopic kidney. The present case report highlights the importance of three-dimensional vision and enhanced maneuverability with the EndoWrist technology of the robotic surg...
