“…6 In fact, urolithiasis was reported in 7 cases. 1,[5][6][7][8][9] In contrast, Liwnicz and colleagues suggested that the formation of stones may be secondary to the mucin secretion from the cystic tumour. 10 They proposed that the secreted mucin may have caused neoplastic formations after fusing with sodium and calcium.…”

“…[1][2][3][4][5][6][7][8][9] Some authors have postulated that the development of mucinous cystadenoma with an intestinal phenotype in the kidney involves urolithiasis, infections, or both, and these events may induce intestinal metaplasia. 6 In fact, urolithiasis was reported in 7 cases.…”

Original research E30Cite as: Can Urol Assoc J 2015;9(1-2):E30-2. http://dx.doi.org/10.5489/cuaj.2211 Published online January 12, 2015. AbstractA 45-year-old man complained of a palpable mass in his left abdomen. Computed tomography showed a horseshoe kidney with a Bosniak type II complicated cyst from a left segment. Three years after his initial examination, due to the growing cystic lesion and the compression imposed on the urinary collecting system and surrounding organs, we performed a left heminephrectomy. The diagnosis was mucinous cystadenoma of the kidney. No recurrence was observed 6 months after surgery. The histopathology was unique since the inner surface of the cyst was covered by a mucin-positive columnar epithelium connected to a urothelium, with continuous transition between the two. This suggests that the mucinous tumour may have originated from a sequestered segment of the renal pelvic epithelium in the renal parenchyma.

“…Tumors of the renal pelvis are uncommon, and the most common neoplasms are urothelial in origin. Mucinous cystic neoplasms of kidney are exceedingly rare primary renal neoplasm, with only 22 cases of mucinous cystadenoma and 5 cases of mucinous cystadenocarcinomas have been reported in English literature 1,2 . Mucinous cystadenocarcinomas of renal pelvis was first described in 1956 by Arcadi et al 3 .…”

Primary mucinous cystic tumors occurring in the renal pelvis or the entire pelvicaliceal system are uncommon. Most are mucinous cystadenoma and less frequently mucinous cystadenocarcinomas. In fact, the publications on these neoplasms are limited to a few cases. Because mucinous cystadenomas of kidney are exceedingly rare, little is known about their natural history, pathogenesis and clinicopathologic features. Herein, we describe a case of mucinous cystadenoma arising from the renal pelvis, which resembled hydronephrosis. The patient presented with a history of intermittent dull pain on the left loin for 6 months. He had no history of removing urinary calculus or long- standing chronic infection in urinary system. The histopathology was unique since the inner surface of the cyst was covered by a mucinous epithelium connected to a urothelium, a transition from non- neoplastic urothelium to mucinous epithelium. This suggests that mucinous cystadenoma of renal pelvis, like its malignant counterpart, may arise in foci of metaplastic mucinous areas. Faridpur Med. Coll. J. Jul 2019;14(2): 104-106
