RT Journal Article SR Electronic T1 A young woman with endometriosis of kidney JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 244 OP 246 VO 27 IS 2 A1 Pinaki Dutta A1 Mohammad H. Bhat A1 Anil Bhansali A1 Vijay Kumar YR 2006 UL http://smj.org.sa/content/27/2/244.abstract AB Endometriosis of kidney is a rare manifestation of a relatively common disease. We report a case in which ovarian and renal endometriosis were diagnosed concurrently. The disease was probably silent for a long time due to coexistent thyrotoxicosis modifying estrogen metabolism. Fine needle aspiration cytology clinched the diagnosis of endometriosis and avoided unnecessary nephrectomy.
