Renal adenomas are benign parenchymal tumors mostly detected incidentally at autopsy. Renal adenomatosis is rare and defined as presence of multiple tubular adenomas in the kidney. Nine renal adenomatosis cases have been reported up to date. Herein, a 20-year-old male patient who had a complaint of discharge from the lomber region skin is presented. In this patient, a retroperitoneal abscess which was fistulized from left lomber region to skin and multiple kidney stones in a nonfunctional kidney were detected after physical examination and imaging, and he was diagnosed with renal adenomatosis following nephrectomy. In immunohistochemical study EMA and low and high molecular weight keratins were positive while CD15, AMACR and RCC marker were negative. Clinical and pathologic characteristics of these tumors, that have histopathologic similarities with low grade (type 1) papillary renal cell carcinoma, with obscure etiology are discussed in the light of literature.
