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.<\/jats:p>","DOI":"10.1136\/bcr-2018-229023","type":"journal-article","created":{"date-parts":[[2019,5,25]],"date-time":"2019-05-25T06:05:53Z","timestamp":1558764353000},"page":"e229023","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Squamous cell carcinoma of skin due to prolonged indwelling percutaneous nephrostomy catheter"],"prefix":"10.1136","volume":"12","author":[{"given":"Ashish","family":"Sharma","sequence":"first","affiliation":[{"name":"Department of Urology, King George\u2019s Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vishwajeet","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Urology, King George\u2019s Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rahul Janak","family":"Sinha","sequence":"additional","affiliation":[{"name":"Department of Urology, King George\u2019s Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1390-6488","authenticated-orcid":false,"given":"Samarth","family":"Agarwal","sequence":"additional","affiliation":[{"name":"Department of Urology, King George\u2019s Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,5,24]]},"reference":[{"key":"2025082701335591000_12.5.e229023.1","doi-asserted-by":"crossref","unstructured":"Goodwin WE , Casey WC , Woolf W , et al . needle) nephrostomy in hydronephrosis.
