Squamous cell carcinoma of skin due to prolonged indwelling percutaneous nephrostomy catheter.

Percutaneous nephrostomy (PCN) catheter placement is a commonly performed procedure in the urological practice for various indications like percutaneous nephrolithotomy, pyonephrosis, infected hydronephrosis and after failed attempt of ureteric stenting. The nephrostomy catheter is usually associated with low complication and morbidity rate, but prolonged indwelling nephrostomy tube may be hazardous in some cases. We hereby report a case of squamous cell carcinoma of skin around the PCN, which was attributed to chronic inflammation and persistent irritation from a long-term neglected indwelling nephrostomy catheter for last 3 years. The patient was managed with wide local excision of skin carcinoma and ureterocalicostomy for pelviureteric junction stricture. The authors report the first documented case with aforementioned presentation. © BMJ Publishing Group Limited 2019. No commercial re-use. See rights and permissions. Published by BMJ.
