"The reported incidence of MCRNLMPs is 1-2% of all renal tumours 2,3. They are typically encountered in middle-aged adults 5. There is a slight male predilection 5."
"The prognosis of these tumours is excellent. There are no reported cases of metastatic spread or local recurrence/growth 5."
"As these tumours are slow-growing and have an indolent natural history they are usually asymptomatic and are found incidentally when imaging of the kidneys is carried out for other indications 5. Occasionally, if the tumour is large it can present with mass effect, haematuria or flank pain 5."
