Renal cancer

A rare case of renal squamous cell carcinoma presenting with psoas sign

“…Renal cancer is a relatively common form of cancer. However, squamous cell carcinoma (SCC) of the kidney is extremely rare, accounting for only 0.5 % to 0.8 % of malignant renal tumors [ 3 ], whereas the renal cell carcinoma (RCC) accounts for about 85 % of renal tumors [ 2 ]. Furthermore, when compared to transitional cell carcinoma, squamous cell carcinoma tends to be more invasive.…”

“…Renal cell carcinomas are known to present with a classic triad of symptoms, which include hematuria, renal angle pain, and a palpable mass. Other potential symptoms may include weight loss or fever [ 3 , 12 ]. In contrast, SCC has a wider range of atypical presentations, encompassing clinical features such as flank or abdominal masses, weight loss, hematuria, lumbago, and paraneoplastic syndromes.…”

“…Adenocarcinoma of the renal cortex is the most common type of renal cancer, comprising over 85 % of diagnosed renal cancer cases. Remaining type of malignancies are transitional cell carcinoma, sarcoma, Wilms' tumor, squamous cell carcinoma and metastatic deposits [ 3 , 4 ]. Squamous cell carcinoma (SCC) of the renal pelvis is rare, accounting for only 0.5 % to 0.8 % of malignant renal tumors [ 4 ].…”
