Abstract
Renal myopericytoma is an extremely rare entity with just 11 cases reported in the literature. We report the case of a 57 year old Caucasian man who was found to have a renal myopericytoma following nephrectomy for suspected renal cell carcinoma. Renal myopericytoma has a distinct morphological overlap with other pericytic tumours and significant histological variation has been noted between cases reported to date. Further characterising this novel tumour is vital to identify subtypes within this spectrum, understand its behaviour and to identify imaging trends which may lead to pre-operative diagnosis in order to potentially avoid radical treatment.
