Any commentary, article, text, image, and so on, useful for this Web site is welcome. We would very much appreciate it if you give us your comments, criticism, and suggestions.

Inside this renal pathology website you will find case discussion, literature monitor, links, and a good renal pathology textbook and atlas: the "Tutorial", that is being continuously updated and improved. The English version of the Tutorial has now the first 18 chapters, in the next months will progressively appear the other 5 chapters. We invite you to visit this Tutorial and to see the many links to complement the information.

I beg all those that visit this site, that if there be anything in it that pleases them, they thank the authors of the texts that we study, to our colleagues who teach us so much, and to the patients from who we learn. But if there be anything that displeases them, I beg them also to impute it to my incompetence, and not to my will, for gladly would have done everything better than I can (adapted from G. Chaucer: The Canterbury Tales).

These pages are edited in Medellín, Colombia, and this work is a product of PRYT group (Renal and Transplantation Pathology [Patología Renal y de Trasplantes]).
