Metastatic invasive mole in the urinary bladder.

We report an unusual case of invasive mole metastasized to the urinary bladder. The patient presented with hematuria one month after evacuation of a molar pregnancy. The serum chorionic gonadotropin levels regressed spontaneously following transurethral cystoscopic resection of the tumour. Metastasis of an invasive mole to the urinary bladder has not been previously reported.
