      We read with great interest the excellent and informative case report by Tevlin et al describing a case of Erdheim-Chester disease (ECD), a form of non Langerhans cell histiocytosis, of the gastrointestinal tract. 1 In the case presented by the authors, a laporotomy was required for definitive diagnosis, as percutaneous biopsy of the retroperitoneal adenopathy was non diagnostic. We would like to share a similar case of this rare disorder, encountered recently in our institution, where a different approach was utilized by performing a percutaneous renal biopsy allowing for the correct diagnosis to be made without the need for laporotomy.
