Abstract:
Primary mucinous cystic neoplasms are rare tumours of the kidney, with a very few case reports in
the literature. They arise from metaplasia of renal pelvic urothelium. We describe here a 45-year-old
male who presented with pain in the abdomen and a lump in the left iliac fossa for two months.
Ultrasound and CT scan showed a large, complex, heterogenous mass in the central abdomen and
left iliac fossa, suggesting the possibility of dermoid cyst. Excision of the mass showed an enlarged
multicystic kidney fi lled with mucin, destruction of renal parenchyma and a small viable area of
grey white tumour. Histopathology revealed a peripherally located mucinous cystadenocarcinoma
arising in the background of chronic pyelonephritis and mucinous metaplasia. We report this case
for the rarity of the lesion and the associated clinical and radiological diagnostic dilemma.
