Phyllodes tumour of the urinary bladder: A report of a unique case

Abstract

Phyllodes tumours (PT) of the male urogenital tract are rare; to date, fewer than one hundred cases have been described in the prostate, and under fifteen in the seminal vesicle.(1) They display histologic features and clinical behaviour similar to PTs of the female breast; the lesions may be cured by surgical resection, but a large proportion exhibit local recurrence, and cases of direct invasion into adjacent organs and widespread metastasis have been reported.(2) Although no single morphologic feature is reliably predictive of prognosis, a combined assessment may be used for grading and prognostication, as in the breast.(2) We encountered a primary urinary bladder PT which, to our knowledge, is the first such case described in a human.
