Renal endometriosis: A benign disease with malignant presentation

Abstract

Endometriosis is a common gynecological disorder in which endometrial tissue is located outside the uterine cavity. Urinary tract involvement by endometriosis is uncommon. Renal endometriosis is a rare disorder and is not evident on imaging. It may be misdiagnosed as malignant disease and patients may undergo invasive procedures for it. We report a case of a young lady who presented with symptoms typical for renal mass, and was diagnosed as a tumor on imaging. Patient underwent radical surgery and histology revealed renal endometriosis.
