Alpha-fetoprotein production by rhabdomyosarcoma of the urinary bladder.

Alpha-fetoprotein has emerged as a useful diagnostic tool for hepatic tumour and tumours of germ cell origin. However, isolated case reports of association of this tumour marker with tumours of the lung and non-germ cell tumours of the ovary are reported. We present a case of a Rhabdomyosarcoma, a generally non-secretory tumour that showed raised levels of AFP in serum and reacted positively for the same in a PAP technique for AFP. Cross striations were visible in many cells on II & E stained sections.
