   Case Report Top


A 35-year-old female presented with history of continu­ous, dull ache on the right side of abdomen for 2 years. She also noticed a slowly increasing mass on the right side 4 months back. She had undergone right-sided pyelo­lithotomy twice, 5 years and 2 years earlier.

On examination a firm, bimanually palpable lump, ex­tending from the right hypochondrium to the right iliac fossa was noticed. No other significant finding was noted. X-ray KUB region showed a 1 cm radio-opaque density in the right renal region. On ultrasonography a cystic, sep­tate mass, 12 x 20 cm in size extending from the liver to the iliac fossa was seen with no obvious renal tissue. Con­trast enhanced computerized tomography of the abdomen and pelvis confirmed a non-enhancing 12 x 15 x 20 cm cystic mass, extending from the liver to the right iliac fossa eroding the iliac crest.

The retroperitoneal mass was explored through a 11 th rib bed incision. It was cystic, adherent on all sides and it ruptured during mobilization with a gush of almost 1 1 of gelatinous material coming out. The mass was removed completely. Gross examination revealed a kidney with a dilated, thin walled pelvicalyceal system and cystic spaces filled with mucinous material [Figure - 1]. Histopathological examination revealed a mucin secreting glandular epithe­lium with large hyperchromatic nuclei without fibrotic reaction suggestive of mucinous cystadenocarcinoma of the renal pelvis [Figure - 2].

Mutinous cystadenocarcinoma of the renal pelvis is a very rare condition with only 95 cases reported so far. [1]

Mucinous cystadenocarcinoma of the renal pelvis is a very rare tumour comprising less than 0.3% of total renal pelvic tumours. [2] The etiology is thought to be due to the unique ability of transitional epithelium to respond with a glandular metaplastic change due to chronic infection or irritation; this metaplasia may occasionally initiate glan­dular tumours. Terris et al reported a case of mucinous adenocarcinoma of the renal pelvis and ureter presenting as chronic flank pain, calculus and hydronephrosis in an immigrant from India. They report a literature review sug­gesting a high frequency of this otherwise rare tumour in India with an inflammatory, environmental or dietary etiology. [3]

Usual features of this tumour include long duration of symptoms, association with calculi and hydronephrosis and a preoperative appearance of an inflammatory condi­tion. The occurrence of this tumour, though rare, should be kept in mind especially if a renal mass lesion is associ­ated with recurrent calculus disease. [2]

This tumour is classically treated by radical excision with postoperative chemotherapy. However, it has a very poor prognosis.
