[Squamous cells carcinoma of the renal pelvis discovered due to parietal and skin invasion: an uncommon manifestation].

We here report a rare case of squamous cells carcinoma of the renal pelvis with abdominal wall skin invasion in a patient with a history of recurrent upper urinary tract infections due to kidney stones. A right lumbar skin lesion was the reason for consultation. Uroscanner showed right renal mass extended to the adjacent soft tissues. Biopsy showed squamous cell carcinoma of the renal pelvis. After having conducted a literature review we can say that this is the first case of squamous cell carcinoma of the renal pelvis detected due to skin invasion.
